BioGRO2®

BioGRO2® for Ammonia Reduction

The discharge of ammonia (NH3) from sewage treatment facilities results in creating oxygen deficient conditions in the receiving water body with detrimental consequences for the receiving streams or lakes. The removal of each kilogram of ammonia requires 4.6 kilograms of oxygen for the nitrification process.

Nitrifying bacteria (which convert ammonia into nitrates) require aerobic conditions.  BioGRO2® is the easiest and most efficient way to deliver high amounts of dissolved oxygen for the ammonia removal process.    

BioGRO2® transfers DO over 15 times more efficiently than conventional methods while utilizing 85% less energy.

BioGRO2® for Biosolids (sludge) Filtrate Treatment

In most conventional treatment plants the filtrate/supernatant from sludge handling facilities is returned to the front end of the plant.  Depending on the processes and the sludge characteristics the filtrate/supernatant is usually has high BOD and ammonia levels.  The BOD adds a significant load to the treatment facility and the ammonia often passes through the plant with minimal treatment making a major contribution to the overall ammonia levels in the plant effluent.

Optimal efficiency will be achieved when BioGRO2® aerates the filtrate streams from the sludge handling process before returning to the plant.
