Caustic Soda = Volatile Price & Volatile Chemistry

CAUSTIC SODA = CHEMICAL VOLATILITY AND PROCESS UPSET

Caustic Soda is a HIGHLY CORROSIVE CHEMICAL listed on the Special Health Hazard Substance List. Caustic Soda on contact can burn the skin and the eyes and can cause permanent lung damage through inhalation. Caustic soda in contact with water can create enough heat to ignite combustibles and the resulting fire will produce poisonous gases. THIOGUARD and THIOGUARD ΩMEGA-S technical grade magnesium hydroxide is an effective, non-hazardous alternative to Caustic Soda. By converting to THIOGUARD, wastewater utilities are able to eliminate hundreds of hazardous bulk tanker truck deliveries, thereby reducing insurance costs.

In addition, Caustic Soda freezes at a temperature of 52 degrees, rendering it useless for water treatment purposes, and creating additional hazards by creating increased pressure at valves with the potential unexpected eruptions or spills. When it comes to safety, Thioguard and Thioguard Omega-S technical grade magnesium hydroxide is clearly superior.

  • Caustic Soda (Sodium Hydroxide) is hazardous to use, detrimental to personnel safety and biological processes
  • Sodium addition to wastewater upsets flocculation, settling, clarification and dewatering processes, driving up needs for polymer or metal salt use.

CAUSTIC SODA = PRICE VOLATILITY

Caustic Soda is pricing is subject to a variety of pressures, from basic supply and demand issues to market manipulation – even international trade can cause price fluctuations. THIOGUARD technical grade magnesium hydroxide offers greater “price reliability,” and delivers a safe and effective alternative to Caustic Soda.

  • Budget Uncertainty
  • Challenging Contract Management when driven to force majeure re-pricing


THIOGUARD Takes the Cake… and Makes it Better.

For a nearly one million gallon a day plant in Lambertville, NJ the good news just kept on coming. First, they started using Thioguard  to condition their primary sludge to reduce odors from the plant. This worked so well, they began to ask, “Where else can Thioguard be applied?”

As the winds whipped in early Spring, it was discovered that a significant amount of odor was coming from the nearly quarter million gallon sludge holding tank at their site. Since Thioguard worked to reduce the primary sludge odors, they wondered if it would work for stored sludge waiting to be pressed.

After establishing a stable pH range of 7.5-8.0 s.u., with just a couple of gallons a day, odors were reduced to satisfactory levels… and then something very interesting happened. Not only were odors in the press building reduced, but the press cake was drier. On average nearly 20-40% drier.

Why? Thioguard is technical grade magnesium hydroxide: a buffered source of alkalinity that is used to increase pH. Elevated pH promotes better polymer performance. Not only that, but due to divalent cation bridging, the press supernatant quality can be clearer as well. Any remaining alkalinity is then returned in the supernatant to the headworks of the plant.

The Lambertville results were recently verified on a much larger scale through bench testing at a treatment plant in Newark, Ohio. The chart below illustrates expected typical annual cost savings in hauling and tipping after the addition of Thioguard at a 100 MGD plant. The bottom line? For every 1% improvement in cake solids, the plant would save approximately $214K in hauling and tipping costs. In multiple tests, the use of Thioguard consistently resulted in 5% to 13% improvement in cake solids with greatly reduced water weight. Drier cake solids means less to haul, and fewer loads translates directly into operational savings.

Nurturing the Brain with Magnesium

Magnesium is everywhere – it does not occur free in nature, only in combination with other elements, but it is the eighth most abundant chemical element in the Earth’s crust and the third most abundant element in seawater; it is even the ninth most abundant in the Milky Way. In the human body, magnesium is the fourth most abundant ion and the eleventh most abundant element by mass, being stored in bones, muscles, and soft tissues.

Magnesium is fundamental for health: it is essential to all cells and to the function of hundreds of enzymes, including enzymes that synthesize DNA and RNA, and enzymes involved in cellular energy metabolism, many of which are vital. Magnesium is involved in virtually every major metabolic and biochemical process in our cells and it plays a critical role in the physiology of basically every single organ.

Low plasma levels of magnesium are common and are mostly due to poor dietary intake, which has lowered significantly in the last decades. Magnesium can be found in high quantities in foods containing dietary fiber, including green leafy vegetables, legumes, nuts, seeds, and whole grains. But although magnesium is widely distributed in vegetable and animal foods, some types of food processing can lower magnesium content up to 90%. Also, the soil used for conventional agriculture is becoming increasingly deprived of essential minerals. In the last 60 years, the magnesium content in fruit and vegetables has decreased by around 20 to 30%.

Symptomatic magnesium deficiency due to low dietary intake in healthy people is not very frequent, but a consistently poor dietary supply of magnesium has insidious effects. Magnesium deficiency alters biochemical pathways and increases the risk of a wide range of diseases over time, namely hypertension and cardiovascular diseases, metabolic diseases, osteoporosis, and migraine headaches, for example.

In the brain, magnesium is an important regulator of neurotransmitter signaling, particularly glutamate and GABA, the main neurotransmitters by modulating the activation of NMDA glutamate receptors and GABAA receptors. It also contributes to the maintenance of adequate calcium levels in the cell through the regulation of calcium channels’ activity.

These physiological roles make magnesium an essential element in important neuronal processes. Magnesium participates in the mechanisms of synaptic transmission, neuronal plasticity, and consequently, learning and memory. Accordingly, increased levels of magnesium in the brain have been shown to promote multiple mechanisms of synaptic plasticity that enhance different forms of learning and memory, and delay age-related cognitive decline. Increased levels of magnesium in the brain have also been linked to an increased proliferation of neural stem cells, indicating that it may promote the generation of new neurons (neurogenesis) in adulthood. This is an important feature because neurogenesis is a key mechanism in the brain’s structural and functional adaptability, in cognitive flexibility, and in mood regulation.

Magnesium supplementation has also been shown to modulate the neuroendocrine system and to improve sleep quality by promoting slow wave (deep) sleep, which, among many other functions, is also important for cognition and memory consolidation.

Furthermore, magnesium may enhance the beneficial effects of exercise in the brain, since it has been shown to increase the availability of glucose in the blood, muscle, and brain, and diminish the accumulation of lactate in the blood and muscles during exercise.

But just as increasing magnesium levels can be beneficial, magnesium deficiency can have serious harmful effects.

Magnesium has important roles in the regulation of oxidative stress, inflammatory processes and modulation of brain blood flow. In circumstances of magnesium deficiency, all of these functions can potentially be dysregulated, laying ground for neurological disorders. Also, in a context of low magnesium availability in the brain, NMDA glutamate receptors, which are excitatory, may become excessively activated, and GABAA receptors, which are inhibitory, may become insufficiently activated; this can lead to neuronal hyperactivity and to a condition known as glutamate excitotoxicity. This causes an excessive accumulation of calcium in neurons, which in turn leads to the production of toxic reactive oxygen species and, ultimately, to neuronal cell death.

Magnesium deficiency has been associated with several neurological and psychiatric diseases, including migraine, epilepsy, depression, schizophrenia, bipolar disorder, stress, and neurodegenerative diseases. Magnesium supplementation has shown beneficial effects on many of these conditions, as well as in post-stroke, post-traumatic brain injury, and post-spinal cord injury therapies. This therapeutic action is likely due to its action in blocking NMDA glutamate receptors and decreasing excitotoxicity, in reducing oxidative stress and inflammation, and in increasing blood flow to the brain, all of which are determinant in the outcome of these conditions.

There are multiple benefits to be obtained from magnesium, both from a health promotion, and from a disease prevention and management perspective. The recommended daily intake of magnesium is of 320mg for females and 420mg for males. Too much magnesium from food sources has no associated health risks in healthy individuals because the kidneys readily eliminate the excess. However, there is a recommended upper intake level for supplemental magnesium, since it can cause gastrointestinal side effects. So, keep it below 350mg/day.

The Solution to Your F.O.G. Problem is Thioguard



The accumulation of fats, oils, and grease can be dramatically reduced through the use of THIOGUARD technical grade magnesium hydroxide. THIOGUARD is a strong base, and a moderate pH adjuster, which adds non-carbonate alkalinity to the wastewater. As pH increases, fats, oils, and grease become more soluble. The practical effect on municipal wastewater systems is a rapid, dramatic reduction in fat, oils, and grease buildup within the collection, transport and treatment structures.

 THIOGUARD does NOT
transfer F.O.G. problems “downstream,”
only to reappear in your plant.

THIOGUARD eliminates the problem, by improving the immediate environment, allowing “good bacteria” to perform their function. By the time the wastewater reaches your reclamation facility, the majority of the F.O.G. has been either consumed or reduced to simpler organics.


The addition of THIOGUARD boosts pH levels, THROUGHOUT your system, PREVENTING the conditions that encourage the deposition of grease, which can clog lines, and accumulate on the surface of pump stations and your treatment plant.
With improved pH, solubility is increased significantly, by a factor of 10x in some cases. THIOGUARD is typically added through a single Feed Unit, and provides multiple benefits throughout your system, from source to discharge.

THIOGUARD provides the greatest power to neutralize acid over long infrastructure distances, while providing additional benefits to your waste water treatment plant’s biological treatment processes. The chart below compares alkalinity per gallon, illustrating the superiority of THIOGUARD against other commonly used treatment options.

THIOGUARD Cuts through F.O.G. and Delivers
Multiple System-Wide Benefits

The benefits of adding THIOGUARD to your treatment processes are not limited to the prevention or reduction of F.O.G., through sustainable and balanced pH levels. THIOGUARD also prevents corrosion and dramatically reduces the formation of sludge – significantly reducing your handling and transportation costs. The benefits are numerous and system-wide, making THIOGUARD the best and most practical choice for your system.

Thioguard vs. Nitrates Do Nitrates Do More Harm Than Good?

Nitrates

Calcium Nitrate products are commonly used in many of the nation’s wastewater collection systems, and they supposedly do one thing – prevent H2S odors. Unfortunately, there are multiple costly and problematic unintended consequences of the use of nitrate products. In addition, while nitrate use may temporarily address H2S odor problems, nitrate products are of little or no use in combating corrosion, which is a tremendous problem both in-plant and throughout every segment of wastewater treatment infrastructure.

NITRATE USE ENCOURAGES UNWANTED BIOCHEMICAL REACTIONS…
where you don’t want them to occur.
Think denitrification…which consumes organics, and produces nitrogen gas N2 and carbon dioxide CO2, all seemingly innocuous by-products of Calcium Nitrate’s intended use as an odor control technology…but let’s take a closer look…

1. Nitrates contribute to the formation of F.O.G.
The addition of nitrates contributes to the accumulation of an odorous film, often referred to as a F.O.G. (Fats, Oils and Grease) mat in pumping stations and at your plant. Blockages associated with F.O.G. have been shown to be the greatest contributors to O&M costs including energy consumption, maintenance costs, and Sanitary Sewer Overflows (SSOs).

2. Nitrates contribute to Gas Binding in the Collection System
The transfer of wastewater can result in the release of gases such as O2 – Oxygen, CO2 – Carbon Dioxide, N2 – Nitrogen Gas, H2S – Hydrogen Sulfide, CH4 – Methane, VOCs – Volatile Organic Compounds, and VOSCs – Volatile Organic Sulfur Compounds, among others. Some of these gases are drawn into the system through pumping and ventilation, while others are generated within the system either chemically or biologically. These gases can result in the development of gas binding in the system, and are dramatically exacerbated with the utilization of calcium nitrate.

3. Nitrates upset the Bio-P process at your plant
The use of nitrates in the collection system alter the chemical and biological conditions of the collection system, which would otherwise facilitate the formation and transport of VFAs to the treatment plant, where they can be used by PAOs in Bio-P processes.

As VFAs (Volatile Fatty Acids) are eliminated with calcium nitrate addition, VFAs are therefore not available for PAOs (phosphorus accumulating organisms) for phosphate removal at the wastewater treatment plant.

4. Nitrates negatively impact Primary and Secondary Clarification
The addition of nitrates is not an exact science, and unfortunately, every step along the way there are costly unintended consequences. Add too little, and you’re facing odor problems. Add too much, and you’re faced with the formation of unwanted bubble-forming gases (N2 and CO2 from denitrification) in your settling tank, exactly where you DON’T WANT IT, continuing the formation of F.O.G. mat, (as well as creating an environment unfavorable to your biological processes). This often results in increased metal salts usage or increased polymer usage and associated increases in costs.

NITRATE ADDITION REQUIRES MULTIPLE FEED LOCATIONS,
THIOGUARD ONLY REQUIRES ONE
Calcium Nitrate has a short half-life in sewers, and therefore many addition locations are required to achieve adequate system-wide control. This requires several addition locations, and corresponding higher costs and operational oversight. In contrast, a single THIOGUARD Feed Unit can often replace several nitrate feed stations, and maintain a relatively constant pH level throughout.

THIOGUARD HELPS PREVENT CORROSION
Maintaining a constant surface pH of 6-8 can reduce the rate of corrosion by as much as 100X. The cost of simply ignoring this problem is monumental and THIOGUARD is the only commonly used product that has a direct mechanism to increase surface pH and prevent corrosion.

CHOOSING THIOGUARD OVER CALCIUM NITRATE WILL: 

  • Decrease maintenance costs
  • Decrease operating power costs
  • Decrease F.O.G. related SSOs and ARV malfunction
  • Improve efficiency due to reduced discharge pressure in manifolded force mains
  • Improve Biosolids
  • Save money and improve plant performance ACROSS THE BOARD!

Enhance Phosphate Treatment with THIOGUARD

In plants currently using metal salts, the addition of
THIOGUARD® technical grade magnesium hydroxide can
REDUCE METAL SALT USAGE BY UP TO 50%

Increased regulation of total phosphorus limits are a fact of life, and another challenge for WWT plant operators and engineers. In most treatment plants, metal salts (ferrous/ferric or aluminum) are added for the treatment of phosphates.

Adding THIOGUARD technical grade magnesium hydroxide will:

  • Minimize or eliminate the addition of metal salts
  • Enhance biological phosphorus uptake in bioreactors
  • Reduce the amount of metal-laden sludge
  • Increase agricultural phosphate recovery
  • Reduce dewatering, handling and transportation costs
  • Eliminate the need for expensive plant upgrades

THIOGUARD is specifically formulated for maximum alkalinity
and magnesium utilization in biological processes, enhancing the
performance of metal salts in removing phosphates chemically –
while simultaneously improving biological uptake in bioreactors.

THIOGUARD improves plant performance
Improved plant performance =
Significant Savings

Thioguard is engineered to provide maximum magnesium hydroxide and sustained alkaline utilization, enhancing the formation of metal hydroxide precipitate and increasing the adsorption of soluble phosphorus.

The benefits of adding THIOGUARD to your treatment processes are not limited to enhanced phosphorus treatment and management. In addition, THIOGUARD is the ONLY commonly used product that has a direct mechanism to prevent corrosion through sustainable and balanced pH levels. You will also benefit from a reduction in the formation of metal-laden sludge – significantly reducing your handling and transportation costs. The benefits are numerous and system-wide, making THIOGUARD
the practical choice for your entire system.

Magnesium’s Impact on Vitamin D Intake

The influence that magnesium has on the way our bodies process vitamin D has big implications for bone health. The studies suggest that taking a magnesium supplement can help people reach their desired level of vitamin D faster. Not only can they reach that level faster, but magnesium may also more effectively facilitate the actions of vitamin D on bone health. An additional 200 mg of magnesium is all it should take to get the average person up to an adequate intake.13% improvement in cake solids with greatly reduced water weight. Drier cake solids means less to haul, and fewer loads translates directly into operational savings.

  • Magnesium is important in regulating levels of vitamin D.

  • Many Americans fail to get enough magnesium as well
    as vitamin D in their diet.

  • Improving levels of both minerals could improve bone strength
    and lower risk of cancer and heart disease.

Don’t Be Blindsided by Lime’s Hidden Consequences

DON’T GET YOURSELF IN DEEP SLUDGE
It’s easy enough to do theoretical calculations and provide exact alkaline equivalents between Lime and Technical Grade Magnesium Hydroxide. However, field and trial experience tells us a more complete story. The amount of high-grade Thioguard – technical grade magnesium hydroxide required to achieve equivalent buffering / performance benefits in the biological reactors tends to be much lower than the calculations would suggest.

Often overlooked are the hidden consequences of lime use, such as softening and pH spikes, and confusion about what standard total alkalinity tests are telling us. An easy way to find out the extent of softening that is taking place in your facility is to filter your sample with a 0.45 micron filter before titration. This will remove the insoluble CaCO3 – calcium carbonate particles that are not “biologically available.” Another significant, yet overlooked impact is the EPA documented sludge production associated with Lime.

POUND FOR POUND, AND IN EVERY STEP OF YOUR PROCESS, THIOGUARD IS SUPERIOR
Compared to Lime, Thioguard is capable of supplying significantly more alkalinity in a bio-available form to a microbial waste-water system without adversely affecting pH.

AVOID A “TRIPLE” NEGATIVE CONSEQUENCE
When you add Lime to your basins, it’s likely you are creating detrimental “Hot Zones” which have the triple negative effect of:

  1. converting soluble alkalinity into an unusable form of alkalinity,
  2. creating an environment hostile to healthy bacteria, killing them off entirely or significantly reducing their ability to function efficiently
  3. converted soluble alkalinity takes up capacity in reactors and increases the inert, inorganic fraction of the operational MLSS

LIME SOFTENING = ALKALINITY REMOVAL
Lime is commonly used in potable water to “soften,”or remove hardness minerals, such as calcium and magnesium from drinking water, in an effort to minimize the effects of potential scaling in the water distribution system. However, in the softening process, calcium and magnesium are removed from water in the form of calcium carbonate (CaCO3) and magnesium carbonate (MgCO3) which are also forms of alkalinity. Removing hardness from water also removes alkalinity. In wastewater, Lime is often considered as an alkalinity supplement. However, the effects of Lime softening can have undesirable consequences to the biological system, e.g., removal of alkalinity, creation of CaCO3 – calcium carbonate sludge, and the potential for bio-upsetting pH spikes.

TRANSPORT SAVINGS
The use of Lime generates significant amounts of sludge in wastewater collections and treatment. On a chemical basis, one ton of Lime can generate as much as 11.5 to 15.5 tons of 20% sludge cake to remove or dispose. In contrast, Thioguard reactions in wastewater produce only water and water soluble products as TDS with NO added sludge. In fact, customers using Thioguard have reported reductions of 15% – 25% in total solids/sludge produced, due to a combination of improved biological performance and reduced inorganic solids loading.

The use of Lime generates significant amounts of sludge in wastewater collection systems and treatment plants. On a chemical basis, one ton of Lime can generate as much as 5 tons of 20% sludge cake to remove or dispose. In contrast, Thioguard reactions in wastewater produce only water and water-soluble products as TDS with NO added sludge. In fact, customers using Thioguard have reported reductions of 15%-25% in total solids/sludge produced, due to a combination of improved biological performance, divalent cation bridging of floc matrix, and reduced inorganic solids loading.

Most wastewater treatment plant operators understand that their wastewater treatment plants function best at some ideal pH and that a minimum amount of alkalinity is required to keep microorganisms happy. But too often, the values of pH and alkalinity are incorrectly used interchangeably, and a thorough understanding of each parameter’s true relationship to biological stability and optimal performance – gets lost in the translation.

Most often this error in terminology stems from the use of common alkaline pH modifiers and alkalinity supplements, such as hydrated Lime. It’s use may successfully meet pH targets, but will likely fall short in supplying adequate alkalinity requirements without adversely elevating pH beyond biologically healthy limits. And often, maintaining pH stability and uniformity across entire treatment basins remains a virtual impossibility.

Unfiltered testing, may cause plant operators to errantly believe there is sufficient soluble alkalinity, or true pH buffering capacity, in the aqueous system. In filtered alkalinity tests, you are removing most, if not all of the insoluble alkalinity, resulting in a much more accurate representation of pH buffering capacity. Better information leads to better decisions. Better decisions lead to improved plant performance.
