Microporous bubble diffuser aerators
Its main functions are:
- (1)aeration, transporting the oxygen in the air into the mixed liquid to meet the respiration requirements of microorganisms in the activated sludge
- (2) stirring and mixing. Since the mixed liquid in the aeration tank is vigorously mixed, the activated sludge, dissolved oxygen and organic substances in the sewage are fully contacted, and sludge precipitation is prevented at the same time.
Usually,aeration is an expensive part of a biochemical wastewater treatment operation, but aerators are being upgraded. Now let’s talk about the advantages and disadvantages of microporous bubble diffuser aerators aerators.
The microporous bubble diffuser has good performance and reliable performance, it is not easy to block the pores, the sewage does not return, the circumferential pressure is uniform, the service life is long, the installation and maintenance are convenient, and the system price is low. The film adopts ternary EPDM, which has high temperature resistance, ozone resistance, acid and alkali resistance and good chemical stability. Compared with the general rubber film, its service life is greatly improved.
The ventilation hole is a straight long hole with good expansion and instant closure. During ventilation, microbubbles with a diameter of less than 3 mm can be released, and the oxygen utilization rate can reach 35-42%. The supporting pipe adopts ABS or PVC material. The air duct is made of engineering plastic ABS, which can be filled with water in a hollow space, and greatly reduces the buoyancy of the aeration system in water.
Injecting oxygen into the sewage can reduce the pollution degree of sewage and industrial wastewater to a certain extent, meet the discharge standard, reduce the repeated pollution of water resources, and achieve the purpose of environmental protection. The machine is easy to operate, and the equipment itself will not cause any pollution to the environment. In addition, for different environments and sewage treatment objects, there are different types of aerators on the market, which can meet the requirements of different industries and objects for sewage treatment, and are suitable for environmental treatment and various industries that require sewage treatment.
