Reducing TKN from a small sewage sys.

Reducing TKN from a small sewage sys.

Reducing TKN from a small sewage sys.

I am looking for a way to reduce TKN from a small (300 m^3/month) sewage system. Water came from a kitchen some toilets and showers that serves around 50 persons per day. TKN max allowed value is 50 mg/l while the actual measured value is 80. I have heard about a biological solution – does anybody also hear and can provide some details?.

More test results: pH=7.5, Temp. =39 deg C. , TSS=56 mg/l, VSS=52 mg/l, COD=313 mgO2/lFe, BOD=90 mg/l, Cl- =105 mg/l, SO4 = 8 mg/l, Ca=27 mg/l, Fe= 1.7 mg/l, K = 20 mg/l, Mg=7 mg/l, Na=60 mg/l, P=8 mg/l, S=11 mg/l.
