Through the analysis of the process flow and water quality situation, the following microbial strains are added into the wastewater: BIOFORM®CW bacteria agent, BIOFORM®CO bacteria agent, Bio-Form®cracking, Bio-Form® nitrogen removal, Bio-Form® nitrification, Bio-Form® decontamination, and NBAAmmonia nitrogen removal bacteria agent. After a month of debugging, the following is the inlet and outlet water quality contrast:

The following is  the effluent water quality data record (two weeks) of Xinfa Pharmaceutical Co., Ltd. The line chart shows that effluent COD is stable under 40 mg/L, ammonia nitrogen is stable under 5 mg/L, proving that Bio-Form's green microbial agents can help the water of system up to standard.
