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

THIOGUARD® is a leading supplier of technical grade magnesium hydroxide and magnesium oxide to the wastewater treatment industry. Thioguard’s Total System Treatment is a non-hazardous application with no required reportable quantities, and is owned, mined and produced in the USA. Thioguard provides more alkalinity than any other additive, it is effective at treating odors, corrosion and FOG (fats, oils and grease), and also provides positive plant benefits for nitrification, biosolids production, digester performance, and chlorination. Thioguard is a division of Premier Magnesia, LLC. For more information, visit http://www.thioguard.com.

Thioguard® is Superior to Lime Slurry and Caustic Soda

ONE OF THE MOST COMMONLY ASKED QUESTIONS IS:
“IF I”M USING X GALLONS OF LIME SLURRY OR CAUSTIC SODA,
HOW MUCH THIOGUARD® DO I NEED?

SOUNDS LIKE A SIMPLE QUESTION, RIGHT?

On the surface, it’s easy to do the theoretical calculations and provide exact alkaline equivalents. However, field and trial experience tells us something different. The amount of high grade Thioguard® – magnesium hydroxide required to achieve equivalent buffering/performance benefits in the biological reactors tends to be much lower than the calculations would suggest. Why?

Often overlooked are some of the side impacts 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 particles that are not “biologically available.” Another significant, yet overlooked impact is the EPA documented sludge production typically associated with lime.

EPA – wastewater technology fact sheet – chemical precipitation: “the addition of treatment chemicals, especially lime, may increase volume of waste sludge up to 50%.”

LIME SOFTENING

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.

Lime SofteningIn 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 sludge, and the potential for bio-upsetting pH spikes.

Hot Zones Temperate ZonesThe simple fact: Thioguard® and lime slurry have different physical and chemical properties that affect how each responds to and reacts with the systems to which they are added. And because of these differences in properties, the impacts they impart and the utility for their use are starkly different.

 DID YOU KNOW…

  • Because of the high solubility of both caustic soda and lime, pH often becomes
    biologically prohibitive before ideal alkalinity levels and process stability can
    be reached.
  • The use of lime in, or prior to, primary treatment can actually reduce alkalinity going into the secondary treatment processes by precipitating CaCO3 in the primary clarifiers
  • Lime produces calcium carbonate in wastewater which acts as a coagulant for hardness and particulate matter.
  • Lime is an effective phosphate removal agent, but results in a large sludge volume and the addition of treatment chemicals, especially lime, may increase the volume of waste sludge up to 50 percent.

Hydrated Lime added in collection systems increases O&M costs
related to formation of scale and accumulated solids/sludge.
In severe cases this leads to line blockages and SSO’s

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.
WHEN COMPARED TO CAUSTIC SODA OR LIME SLURRY
THIOGUARD® IS SUPERIOR

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 the most common alkaline pH modifiers and alkalinity supplements, caustic soda and lime, where their use may successfully meet pH demands, 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.

Compared to caustic soda or lime, Thioguard® is capable of supplying significantly more alkalinity in a bio-available form to a microbial wastewater system without adversely affecting pH. This creates a more suitable environment for bioremediation of BOD and nutrients like nitrogen and phosphorus. Moreover, because magnesium supplies a light-weight, divalent cation, unlike the monovalent sodium in caustic, and heavier calcium in lime, Thioguard® helps to generate a denser, more easily dewatered sludge, with a higher percentage of cake solids.

Lb.s Alkalinity Per Gallon

DID YOU KNOW…

  • It takes 100+ mg/L of Thioguard® to raise a water sample to pH 8.8.
  • This same 100 mg/L of Thioguard® has the same neutralizing power as 138 mg/L of caustic soda and 135 mg/L of lime and would be the equivalent of, though significantly more reactive than, adding 172 mg/ L calcium carbonate alkalinity on a CaCO3 basis, assuming 100% bicarbonate conversion.
