Historically, iron compounds have been added to anaerobic digesters for odor control. However, Iron is responsible for a multitude of unintended consequences in digesters. Premier Magnesia and Thioguard have been using magnesium hydroxide to improve operation of anaerobic digesters for over 30 years. Magnesium hydroxide is an alternative to iron that will actually improve the operation of the digester. The table below clearly illustrates the benefits and COST SAVINGS when magnesium hydroxide is substituted for iron in anaerobic digesters.

If the owner or operator is concerned with struvite formation, THIOGUARD has a model to predict struvite formation potential and has a proven solution that will prevent struvite formation, if predicted by the model. THIOGUARD Ī©MEGA-S actually prevents struvite formation. Do not let unwarranted concerns over possible struvite formation prevent your utility from reaping the benefits of magnesium hydroxide in your anaerobic digesters.
