Magnesium Hydroxide
Magnesium hydroxide provides a fast and easy to use way to stabilize anaerobic digesters in the event they go sour or are accepting acid waste streams. This product is helpful if an anaerobic digester goes sour and the pH needs to be neutralized.

Product Details
pH Control and Alkalinity Buffer for Anaerobic Systems
Magnesium Hydroxide is a highly effective alkalinity supplement designed to stabilize pH and support optimal conditions for anaerobic digestion in municipal and industrial wastewater treatment systems. It provides a slow-releasing, sustained source of alkalinity that helps buffer against sudden pH drops, protecting sensitive methanogenic bacteria and promoting consistent biogas production.
Compared to quick-reacting chemicals like caustic soda, Magnesium Hydroxide offers a safer, longer-lasting solution for managing acidic loads, particularly in anaerobic digesters and high-strength waste streams. Its gradual release minimizes the risk of overcorrection, supporting a balanced microbial environment and reducing the likelihood of process upset or toxicity events.
This product is ideal for facilities that experience frequent organic loading spikes, low influent alkalinity, or difficulty maintaining stable pH. It also supplies essential magnesium, a key nutrient for microbial growth, helping improve sludge quality and overall system efficiency. Compatible with a wide range of biological processes, Magnesium Hydroxide is easy to dose and integrates seamlessly into standard operational protocols.
For reliable pH control, improved anaerobic stability, and long-term protection of biological systems, Magnesium Hydroxide is the preferred buffering solution trusted by wastewater professionals.

Exact Dosing Bench Test
- Prepare Chemicals: Make a slurry mixture of 50g of magnesium hydroxide and 1000 mL of distilled water. Add the slurry to a bottle with a cover so it can be shaken up regularly.
- Prepare Sample to Be Tested: Collect 500 mL of well-mixed (if possible) anaerobic digester sample in a 1000 mL beaker. Place the beaker on a mixing plate with a magnetic stir or put in a 1000 mL beaker with mixing.
- Add Magnesium Hydroxide Until Desired pH is Achieved: Test and record the initial pH, then add 5 mL portions of magnesium hydroxide. After each 5 mL magnesium hydroxide addition, mix the digester sample for 3 minutes and then test and record the pH and add another 5 mL until the pH is at 7. Magnesium hydroxide should be shaken or mixed before each 5 mL addition.
- Calculate Dose Required for Full Scale Treatment: Once the pH reaches 7, the dose of 5 mL equates to 210# of magnesium hydroxide per 100,000 gallons digester volume. This means you will need to add 210 pounds of Boost N Lock per 100,000 gallons digester volume or other solid pH adjuster for each 5 mL added to the beaker.
