Side channel blowers role of Sewage treatment

First.Easy MBR innovation: In the field of sewage treatment plants and water resources recycle, MBR, also called Membrane bio-reactor, is a new type of water treatment technology integrating triggered sludge approach and Membrane separation innovation. There are lots of kinds of membrane, according to the separation mechanism of the category, response membrane, ion exchange membrane, osmotic membrane, etc. According to the category of membranes, there are natural membranes (biofilms) and artificial membranes (natural membranes and inorganic membranes); According to the membrane structure type category, there are plate type, tube type, spiral type and hollow fiber type.

Process composition: The membrane - bioreactor is generally composed of membrane separation module and bioreactor. The commonly discussed membrane-bioreactor is actually the general term of three kinds of reactors: ① oxygenated membrane-bioreactor (AMBR); ② Extraction membrane-bioreactor (EMBR); ③ Solid-liquid separation membrane bioreactor (MBR).

Second. Attributes of MBR procedure: Compared to lots of traditional biological water treatment processes, MBR has the following primary qualities:
(1) high quality and stable effluent water quality
(2) little surplus sludge output
(3) small footprint, not restricted by setting events
(4) can get rid of ammonia nitrogen and refractory raw material
(5) practical operation and management, Easy to recognize automated control
(6) easy to change from the conventional procedure
(7) MBR membrane-bioreactor likewise has some shortcomings, mainly in the following aspects:
o membrane expense is high, so the membrane - bioreactor facilities financial investment is higher than the standard wastewater treatment procedure;
o film contamination is simple to appear, which brings hassle to operation and management;
o High energy intake.


Third, sewage treatment procedure: Sewage treatment the entire procedure for raw sewage through the coarse screen after sewage lift pump ascension through the grille or sand filter, then go into the grit chamber, after sand water separation of wastewater into the settling basin for the first time, more than for primary treatment (specifically physical treatment), the pond water into biological processing equipment, at the beginning of the triggered sludge and biological membrane method, (consisting of aeration tank reactor of triggered sludge method, oxidation ditch, etc, biological membrane approach consisting of biological filter, biological turning disc, biological contact oxidation and biological fluidized bed), biological treatment of effluent into the secondary sedimentation tank, the second pond, the water is decontaminated emissions or getting in tertiary treatment, main treatment to the end of the for secondary processing, The tertiary treatment consists of biological nitrogen and phosphorus elimination, coagulation and rainfall, sand filtering, activated carbon adsorption, ion exchange and electrodialysis. Part of the sludge in the secondary sedimentation tank is returned to the primary sedimentation tank or biological treatment equipment, and part goes into the sludge concentration tank, and then gets in the sludge digester. After dewatering and drying devices, the sludge is finally utilized.

The function of Dereike Side Channel Blower in sewage treatment.

(1) The primary function of the high-pressure fan in sewage treatment is to aerate into the water to improve the material of oxygen in the water, so regarding get rid of iron and manganese or promote the degradation of raw material by aerobic microbes, so as to achieve the function of eliminating oxidized precipitated substances;.

(2) Aeration can make water and air completely call to exchange gaseous substances to remove unstable compounds in water, such as getting rid of the odor of water or damaging gases such as carbon dioxide and hydrogen sulfide.

(3) The high-pressure fan does not need to be maintained, nor does it require to be oiled. So it conserves the employees time. In terms of cost, it can conserve one-third or even half of the procurement cost.
