All wastewater treatment COD, BOD, NH3-N and TN reducing by activated sludge bio-treatment
Waste water bacteria microbial treatment

1. BWG-204, is a mixture of different bacterie, we have already tested in many plants in Chinese market.
2. Aerobic bacteria agent has good degradation function on organic matter in water. Because of spore bacteria has extremely strong resistance to harmful factors of outside world. It can make the sewage treatment system has higher ability of resist impact load, and has strong handling capacity , the system can run properly when the sewage concentration changing dramatically ,ensure effluent discharge stability.
3. Aerobic bacteria agent can remove BOD, COD and TTS effectively. Improve the solid settling capacity in sedimentation basin significantly, increase the number and diversity of protozoa.
4. Start and Recovery System quickly, improve processing capacity and impact resistant ability of the system ,reduce the amount of residual sludge generated effectively ,reduce the use of chemicals such as flocculant ,save electricity.

Advantages Of BWG Bio-Cleaning Agent

1. 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;
2. Solve sludge bulking problem that easily occurs in biological tank;
3. Increase the COD removal rate to 90% in biological system, remove 50% of TN, NH3-N can drop to almost Zero;
4. Withstand 4% high salinity environment;
5. Suitable for all kinds of wastewater, especially for difficult chemical industrial wastewater;
6. 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.

1. According to water quality index into the biochemical system of industrial waste water:the first dosage is about 80-150 grams/cubic (according to volume calculation of the biochemical pond).
2. If it has too big impact on biochemical system caused by fluctuations feed water, the improved dosage is 30-50 grams/cubic (according to volume calculation of the biochemical pond).
3. The dosage of municipal waste water is 50-80 grams/cubic (according to volume calculation of the biochemical pond).
4. The test shows that the following physical and chemical parameters for bacteria growth is most effective:
5. PH: in the range of 5.5 and 9.5, most rapidly growth is between 6.6~7.8, the practice proved the best processing efficiency in PH 7.5.
6. Temperature: it will take effect between 8℃~60℃. Bacteria will die if the temperature is higher than 60℃. If it is lower than 8℃, it will not die ,but the growth of bacteria will be restricted a lot. The most suitable temperature is between 26~32℃.
7. Dissolved oxygen: the dissolved oxygen at least 2 mg/l in the aeration tank of waste water treatment ; the metabolism and degradation speed of high resilience bacteria to target substance will accelerate 5~7 times with enough oxygen.
8. Trace Elements : Proprietary bacterium group will need a lot of elements in its growth , such as potassium, iron, sulfur, magnesium, etc. Normally , it contains enough elements in soil and water
9. Salinity: It is applicable in salt water and fresh water ,the maximum tolerance of salinity is 6%
10. Poison resistance : can more effectively resist chemical toxic substances, including chloride, cyanide and heavy metals ,etc.

Notice: when the contaminated ares containing fungicides, should research the effect of them for microorganisms in advance.
