the COD of inflow is about 1,000 ppm, the wastewater deal by settling tank ,activated sludge tank(MBBR/first and second aerotion tank) ,DAF and sand filter, the COD of effluents is below 100 ppm,the process for COD remove is all right;the NH3-N of inflow is about 20~30 ppm,the NH3-N reduction rate deal by aerotion tank is not stable, and the NO2-N and NO3-N generate in the aerotion tank is not normal. I guess the DO may be a factor, but I do not know why we lower the DO in the second aerotion tank, and the NO2-N is decreased and NO3-N is increased.

Most commonly BOD / COD are measured and calculated on carbonaceous bases, and few ones on nitrogen which is more reactive

the wastewater come from the units of Epichlorohydrin, vinyl chloride, polyvinyl chloride etc.,and the flow rate of this wastewater is about 15,000~20,000 M3/D.

we can offer our zero emission AOP solution to re-purify or treat your wastewater meeting legal discharge standards at low operating costs
to consider retrofit of your WWTP a basic engineering analysis must be done based on the influent-effluent qualities, HRT and basic stream parameters.
