BWG Bio-Cleaning Agent
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.
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.
Case : Project in Another Textie Printing & Dyeing Plant
This company use reactive dye for cotton yarn dyeing.
Before Use Introduction
After biological treatment, COD about 300mg/l, ammonia nitrogen around 10mg/l, deep purple red, and then through the decolorizing agent treatment (dosage 150ppm, cost 1.35 yuan/ton of waste water), COD about 180mg/l, ammonia nitrogen around 11mg/l, lavender red, sludge 2~3 tons/day, local discharge standard is COD less than 200mg/l, ammonia nitrogen less than 20mg/l, colority less than 80times.
Target of the plant for aerobic biological treatment, treated water: COD <150 mg/l, to leave a safe margin with discharge standard, reduce colority, reduce the amount of decolorizing agent (or without decolorization agent).
After Use Introduction
After using BWG-204, in the first seven days, ammonia nitrogen daily slowly reduced from 12mg/l, on the seventh day, dropped to 2mg/l;
After using BWG-204, the discharge of the COD value dropped from the 300mg/l to less than 130mg/l, the dissolved oxygen situation has not improved, limited by the hardware, if increase capacity of the blower, increase aeration diffuser,, it would increase dissolved oxygen, then COD have a certainty down to 80mg/l or less.
The plant improves the hardware to increase dissolved oxygen, After using BWG-204 for two weeks, then COD dropped from the original 300mg/l to 70mg/l.
