BWG Bio-Cleaning Agent
Product Introduction
BWG is a special product developed according to the unique characteristics of the organism when it grows. It has special high efficiency for various types of industrial wastewater, especially for textile wastewater, we got very good treatment results.
We have been continuously improving this product in the past five years, successfully overcome various problems in the actual operation of common micro-organisms, it can be used as biological strengthening technology in the biological aeration tank, to ensure that the treated water to be discharged at higher standard or be reused at higher quality. Solve the problem of biological treatment in short time and get better removal of COD, BOD, NH3-N and TN.
This product is suitable for activated sludge process.
PACKAGE:20KG PP WOVEN BAGS.
Case 7: Project in a Poyester Dyeing And Printing Plant
Wastewater Information
The palnt is a polyester dyeing and printing enterprises mainly use disperse dye. The waste water mainly comes from the dyeing & printing workshop. The water temperature is 120~130ºC.

Before Using BWG
Before, after the Aerobic biological process, the COD was 200mg/l, ammonia nitrogen was 16mg/l, light purple color, sludge amount 1.5 tons per day.
The plant's target is that treated water should be COD <100mg/L, ammonia nitrogen <5mg/L, colorless transparent clear and can be recycled after treatment.
After Using BWG-204 Introduction
- After using BWG-204, the ammonia nitrogen reduced slowly every day from 16 mg/L, and dropprd to 0.48 mg/L on the seventh day.
- COD reduced from the original 200mg/L to 78mg/L, and it maintained stable.
- The wastewater color is reduced from dark purple to slight red color,and can be decolorized by the decolorizing agent.
The Advantages Of BWG Bio-Cleaning Agent
- There are a lot of organism carriers in biological system, it can increase biological tank treatment capacity, greatly improve the shock resistance of biological system;
- Solve sludge bulking problem that easily occurs in biological tank;
- Increase the COD removal rate to 90% in biological system, remove 50% of TN, NH3-N can drop to almost Zero;
- Withstand 4% high salinity environment;
- Suitable for all kinds of wastewater, especially for difficult chemical industrial wastewater;
- When WWTP has breakdown of biological system because of shock loading or other reasons, BWG can be used as stabilizer to restructure biological system and ensure the stable operation of the system in short time (in one week).
- Depending on our application cases' datas from leather wastewater, printing & dyeing wastewater, chemical wastewater, show that when the biological system is running stably, it can reduce usage of other coagulants with WWTP or stop using coagulants, reduce generation of sludge, and greatly reduce the comprehensive cost.
