|Main ingredients||bacillus & coccus which can grow spore(endospore)|
|Content of viable bacteria||≥200calculate/gram|
|Applicable field||municipal sewage, chemical sewage, printing & dyeing sewage,
landfill leachats, foodstuff sewage and other anaerobic system for
■ If the salt content in sewage reaches 10%(100000mg/l),the
bacteria will take acclimatiion and biofilm formation on
biochemical system quickly.
■Improve the efficiency of organic pollutant removal,to make sure
the BOD,COD&TSS content is OK for brine sewage.
■If the electric charge of sewage has large fluctuation,bacteria
will strengthen the settleability of sludge to improve the effluent
(calculated by biochemical pond),for industrial sewage,first dosage
should be 100-200 gram/m3;for municipal sewage,dosage should be 50-80 gram/m3.
The tests show that the following physical and chemical parameters
on bacteria growth is the most effective:
■ PH: average range between 5.5 to 9.5, it will grow most rapidly
between 6.6 -7.8 , and best ph value is 7.5.
■ Temperature: take effect between 8 ℃ - 60 ℃.Bacteria will die if
the temperature is higher than 60 ℃. If it is lower than 8 ℃ ,
bacteria will not die, but the growth of bacteria cell will
berestricted a lot. The most suitable temperature is between 26-32
■ Dissolved oxygen : aeration tank in sewage treament,dissolved
oxygen content is 2 mg/liter.The metabolic and regrade rate of
bacteria could speed up by 5-7times with fully oxygen.
■ Micro-elements: proprietary bacteria group will need a lot of
elements in its growth, such as potassium, iron, calcium, sulfur,
magnesium, etc., normally it contains enough mentioned elements in
soil and water.
■ Salinity: it is applicable in high salty water,the maximum
tolerance of salinity is 10%.
■ Poison resistance: can more effectively resist chemical toxic
substances,including chloride,cyanide and heavy metals,etc.
* When the contaminated area contains biocide,need to test the
sffect to bacteria.
