Struvite formation

Struvite formation occurs when magnesium, ammonium and phosphate hexahydrate combine in the exact chemical formulation as expressed by the equation Mg2+ + NH4+ + HPO42- + 2H2O <---> MgNH4PO4•6H2O + H+ . This is the chemical term and formulation for struvite.

Why Struvite Forms

In laymen language struvite forms in anaerobic digester systems, which are found at wastewater treatment plants, when the elements of magnesium, ammonium and phosphate come together in a liquid solution whose temperature is cool to semi-warm with a high pH. Wastewater treatment plants, which are processing human waste containing the element urea, has a bountiful supply of ammonia because urea when broken down turns into ammonia.

How To Remove Struvite
Phosphates enter the wastewater treatment plant’s liquid solution through dishwasher soap and laundry detergent that citizens have contributed through their homes and businesses drains leading to the plant. Magnesium is an element found in soil, sea water and is an element found in our drinking water.

Struvite formation is especially difficult to prevent under normal conditions for plants utilizing the Biological Nutrient Removal process, better known as the BNR. Under this system the plant is mandated to remove “Total Nitrogen” and “Total Phosphate” before the wastewater is released back into the water, i.e., an ocean liner traveling from Point A to Point B.

Struvite Formation Locations

There are several locations in a wastewater treatment plant where struvite will form. The first location that may occur is from an accumulation in the piping, especially in the elbows where there is a great deal of turbulence. If there is the slightest build up and you attempt to remove the struvite unsuccessfully, struvite formation will occur within days on the small crystals still in the elbow. The same will hold true for the plant’s centrifuges, pumps, belts and other equipment where there is a high velocity of turbulence. Another secret hiding place for struvite is in the lining of the anaerobic digester.

Struvite Formation Tale Tell Signs

• A high pH is a warning for the potential to form struvite
• High conductivity increases the potential for formation
• Low temperatures foster the environment for formation
• Higher concentrations of ammonium, phosphate and magnesium

Prevent Struvite Formation with Proactive Actions

JS 9310 is a liquid formula manufactured by Jayne Products in Carson, California. It has proven time after time in wastewater treatment plants that the utilization of JS 9310 will prevent struvite formation. The application of JS 9310 on a daily basis with small doses of liquid has proven that the prevention of struvite on a consistent, daily basis is possible and also a certainty.
