ACHIEVING A HIGH-QUALITY EFFLUENT THROUGH THE USE OF LOW-COST MECHANICALLY SIMPLE TREATMENT TECHNOLOGY

Dual power multicellular (DPMC) aerated lagoons provide a low cost, low technology alternative to more complex waste treatment systems while not compromising the quality of effluent. Data from several DPMC aerated lagoons located in the Southeast demonstrate an ability to meet secondary effluent limits for a sustained period of time. When coupled with another low treatment technology, the intermittent sand filter (ISF), advanced treatment can be realized producing effluent ammonia-nitrogen results XXX 2 mg/l.Thus, the use of these “low technology” treatment alternatives produce similar quality effluents as compared to other processes for a fraction of the cost.
