Comparison of the advantages of MBR flat sheet membranes and hollow fiber membranes

The applicable mixed liquor suspended solids (MLSS) concentration range for MBR flat sheet membranes is 6000-10000 mg/L, which is significantly higher than that of hollow fiber membrane bioreactors. The MBR flat sheet membrane module structure is assembled from multiple membrane elements arranged in an array, achieving controllable inter-membrane gaps, facilitating online cleaning of the membrane surface with gas-liquid mixing, and exhibiting excellent antifouling performance.

Introduction to the characteristics of the MBR flat membrane device

The water device in the MBR membrane module has the function of a container, which can collect anaerobic pools, MBR bioreactors, sludge pools, equipment operation rooms, etc. In a larger box, the structure is compact, the process is simple, and the footprint is small, generally only 1/3-1/2 of traditional wastewater treatment equipment. In addition, it is convenient for later incremental expansion, high automation operation, and simple maintenance. It can be directly transported to the target location for direct large-scale processing.

Introduction to the advantages of integrated wastewater treatment equipment

Many wastewater treatment integrated equipment processes are currently used domestically and internationally, including activated sludge process and biofilm process. Common aeration methods, oxidation ditch methods, A/B methods, and A2/O methods belong to the former in China, while biological rotating disc methods and contact oxidation methods belong to the latter. Integrated wastewater treatment equipment integrates a primary sedimentation tank, a primary and secondary contact oxidation tank, a secondary sedimentation tank, and a sludge tank. Aeration is carried out in the primary and secondary contact oxidation tanks, making it a contact oxidation device. The effective combination of activated sludge process and biofilm process combines the advantages of both and overcomes their shortcomings.

Application fields of integrated wastewater treatment equipment

The main treatment method of integrated wastewater treatment equipment is the contact oxidation method of biological treatment technology. The design of integrated wastewater treatment equipment is mainly for the treatment of domestic sewage and similar industrial organic wastewater. Main components: 1, hydrolysis acidification pool; 2, contact oxidation pool; 3, impurity sedimentation pool; 4, disinfection treatment; 5, sludge aerobic digestion pool.

Some knowledge points about integrated wastewater treatment equipment

According to manufacturers of integrated wastewater treatment equipment, such equipment integrates a primary sedimentation tank, two-stage contact oxidation tanks, a secondary sedimentation tank, and a sludge tank. Aeration occurs in the two-stage contact oxidation tanks, effectively combining contact oxidation and activated sludge methods.

Some common sense about integrated wastewater treatment equipment

According to wastewater treatment equipment manufacturers, integrated wastewater treatment equipment is a highly integrated device with contact oxidation as its core. The activated sludge method can be integrated into bar screens, equalization tanks, anaerobic tanks, anoxic tanks, aerobic tanks, secondary sedimentation tanks, disinfection tanks, and sludge tanks. Integrated wastewater treatment equipment removes COD, BOD, NH3-N, SS, and total P. It is effective in treating domestic sewage and sewage with pollutants similar to domestic sewage.

Process and characteristics of integrated wastewater treatment equipment

According to wastewater treatment equipment manufacturers, integrated wastewater treatment equipment is a type of integrated wastewater treatment device. It integrates BOD5, COD, and NH3-N removal, and has advantages such as stable and reliable technical performance, good treatment effect, low investment, automatic operation, convenient maintenance and operation, small footprint, and no heating required.

Dry goods sharing, one minute to understand the process flow of water purification equipment

What is the process flow of water purification equipment? Let's take a brief look together. 1. Raw water tank. Stores raw water to allow large particulate matter and other settleable substances to settle out, and buffers the impact of unstable raw water pipe pressure on the water purification equipment system (e.g., pressure-sensitive reactions caused by low or high water pressure).
