Question

Question 3 (30) a) Please name four anaerobic processes. b) Design an UASB treating wastewater from seafood processing industry. The wastewater flow rate was 10,000 m/day and the concentrations of COD, TKN and TP were 12,000 mg/L, 200 mg/L and 60 mg/L respectively. c) At the steady state, the ratio of COD: N: P should be maintained by 300:5:1 for the UASB. If the system achieve COD removal efficiency of 90%, estimate concentration of TKN and TP in the effluent of UASB. 1/2

Answer 1

Four examples of anerobic processes are as follows :

1) alcoholic fermentation

2) lactic acid fermentation

3)anerobic waste water treatment

4) 1st stage of cellular respiration
