BER is a continuous-flow biosolids treatment process that sterilizes (beyond 503 requirements), stabilizes, and deodorizes the biosolid mass produced in a municipal wastewater treatment plant.

The BER process converts the biosolids to a Class A, enhanced "exceptional quality", nutrient-rich fertilizer, ready for market.

The BER process dramatically reduces the operator's solids handling costs by eliminating digestion and disposal.

This building at Payson, Arizona (Northern Gila County Sanitary District - NGCSD) houses the solids treatment stream, including dewatering, chemical sterilization-conversion, and drying-pelletizing.  It produces 2.0 + tons/day dry N:P:K fertilizer pellets.  This plant serves a population of 15,000+. 

The BER process takes little room relative to the served facility.  It simply requires a source of waste-activated sludge.

It eliminates digesters, lagoons, drying beds, composting, liming, hauling and disposal.

Solids enter the process as a 14 to 18% dewatered cake, and leave as a granular 95%+ dry fertilizer product in 1 ton bulk bags or 40-50 lb retail bags.  

Some of the fertilizers Produced Using The BER Process:

5-20-0 Using Ammonia and Phosphoric Acid

10-10-10 Using Sulfuric Acid, Phosphoric Acid, Ammonia and Sulfate of Potash

10-0-10 Using Sulfuric Acid, Ammonia and Sulfate of Potash

The entire process is accomplished in minutes.

The BER process is housed in the building adjacent to (above) the two clarifiers.

The BER process can be scaled to handle the solids of any size municipality.
