High Efficient Bateria Biological Treatment Agent Used in Aerobic Tank for COD BOD NH3-H Reducing
There are a lot of organism carriers in a biological system, it can increase biological tank treatment capacity, greatly improve the shock resistance of the biological system;
Solve sludge bulking problem that easily occurs in the biological tank;
Increase the COD removal rate to 90% in the 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 the breakdown of the biological system because of shock loading or other reasons, BWG can be used as a stabilizer to restructure biological system and ensure the stable operation of the system in short time (in one week).
Depending on our application cases’ data from leather wastewater, printing & dyeing wastewater, chemical wastewater, show that when the biological system is running stable, it can reduce usage of other coagulants with WWTP or stop using coagulants, reduce the generation of sludge, and greatly reduce the comprehensive cost
How to use it?
|1||BWG is added in aerobic biological tank directly.|
|2||1st day use BWG, the dosage is 0.1% of daily wastewater volume, for example, when daily wastewater treatment volume is 4000m3, the first time to add BWG is 4 tons(if biological water stay time is more than 12 hours, dosage is 0.1% of biological tank volume/m3);|
|3||After 1st day dosage, every day dosage of BWG is 0.01% of wastewater volume, such as the daily treatment of 4000 m3 of wastewater, the daily dosage is 400 kg|
|4||If used in chemical industrial wastewater, because the chemical wastewater organic matter is very single situation, need to add extra nutritional sources, such as glucose, flour and other easily degradable organic compounds as carbon resource;|
|5||biological conditions must be conducted under the normal biological conditions, such as: PH value to be maintained in the range of 6 to 9, the inlet water temperature not over 47°C, solution oxygen to be maintained in 2 to 5mg/l, sludge concentration to be controlled in around 5000mg/l, SV30 to be controlled over 30%.|
