Industrial Laundry Wastewater Treatment PE02 HDPE Filter Media

PE02 HDPE Filter Media Bio Carrier Media For Water Treatment In White

Product Description

Biofilm reactors are divided into fixed bed and flow bed. In the fixed bed, the biofilm carrier is fixed. In the traditional sewage treatment system, the main technology is the fixed bed biofilm technology. However, there are some problems in the traditional fixed bed biofilm process, such as less effective contact between microorganisms and sewage, easy blockage of filter material, periodic back washing, and difficult replacement of fixed packing and aeration equipment under packing. In recent years, the performance and stability of MBBR have been improved continuously, which has become an important technology of sewage treatment.

It not only integrates the advantages of activated sludge process and biofilm process, but also overcomes the disadvantages of both. It has the advantages of high processing capacity, low energy consumption, no blockage, compact structure, no sludge reflux, simple maintenance and management.

Film hanging method - mud discharge method

The methods of membrane hanging include free membrane hanging, inoculation and rapid mud discharge.

The rapid sludge discharge method generally adopts activated sludge inoculation. After the sewage to be treated contacts with the inoculated sludge for a period of time without aeration, the sludge water mixture is discharged, and then the continuous small flow of water enters and aerates at the same time until the stable operation.

The influence of packing characteristics on film hanging

The factors of biofilm adhesion are closely related to the surface roughness, specific surface area, hydrophilicity, structure and so on. The surface roughness is large, the microorganism is easy to attach and grow on the surface of the packing, and the film hanging speed is fast; the larger the specific surface area of the packing, the easier the microorganism attaches, and the faster the biofilm grows; the microorganism itself belongs to the hydrophilic particle, so the hydrophilic packing is easy to promote the formation of the biofilm; the structure of the packing itself determines its adaptability to the hydraulic shear force in the aerobic environment . The structure of MBBR packing, the biofilm formed in the early stage of membrane hanging, can better resist the hydraulic erosion.

Disadvantages of low price fillers

As we all know, filler is the core of MBBR Process. Therefore, the performance of the filler directly affects the difficulty of membrane hanging, the amount of biomass in the reactor and the treatment effect of the reactor.

For low-cost fillers, the factory may use recycled materials, or the wall thickness is very thin, or add fillers such as calcium carbonate. During the operation, with the passage of time, the agitator stirs, the fillers may be broken in the reaction tank. However, the filler is a kind of non degradable material, which is difficult to clean in the reaction tank, but becomes a kind of pollution.

Jiangsu Huisen Environmental Protection Technology Co.,Ltd.was founded in 2006 and located in the Environmental Protection Industrial Park,Yixing City,Jiangsu Province,China.The company specializes in the production of various kinds of fillers,aerator and environmental protection equipment,etc.The company focuses on researching and developing all kinds of novel sewage treatment filler and aerator system.
