Top MBR Wastewater Treatment System Supplier | Custom Solutions

As an mbr wastewater treatment system supplier, Qingdao Jinwantong provides membrane bioreactor equipment and integrated sewage treatment systems for projects requiring compact layout, stable operation and high-quality treated water. MBR stands for Membrane Bioreactor, a process that combines biological wastewater treatment with membrane separation.

In an MBR system, microorganisms degrade organic pollutants such as COD and BOD in the biological reactor. Under proper design conditions, the system can also support ammonia nitrogen removal through nitrification. After biological treatment, membrane modules separate treated water from activated sludge, suspended solids and many microorganisms. Compared with conventional biological treatment using secondary sedimentation, MBR can produce clearer effluent and reduce dependence on large clarifier tanks.

A complete MBR wastewater treatment system usually includes a mechanical screen or grille, equalization tank, biological reactor, membrane tank or submerged membrane modules, aeration system, blower, suction pump, backwash system, chemical cleaning unit, sludge discharge system and electric control cabinet. According to wastewater characteristics, the system can also be combined with DAF machines, CPI oil-water separators, automatic dosing systems, activated carbon filters, disinfection units or sludge dewatering equipment.

A typical process flow is:

For B2B buyers, selecting the right MBR system is not only about treatment capacity. Important design factors include daily flow rate, peak flow, wastewater source, inlet COD, BOD, SS, ammonia nitrogen, oil content, pH, temperature, discharge or reuse standard, available space and automation requirements. Membrane flux, aeration intensity, sludge conce

ntration, cleaning frequency and pretreatment quality also affect long-term operation.
MBR wastewater treatment systems are suitable for residential communities, hotels, schools, hospitals, office buildings, municipal wastewater stations, industrial parks and decentralized sewage treatment projects. They are especially useful where land is limited or where stable effluent quality is required for discharge or reuse.

However, MBR is not suitable for every wastewater without pretreatment. Wastewater containing high oil, grease, fibers, high suspended solids, toxic chemicals or high salinity may require screening, DAF, oil-water separation, dosing or other pretreatment before entering the biological and membrane system.

Qingdao Jinwantong can provide single MBR equipment or complete wastewater treatment systems. To receive a suitable proposal, buyers can send treatment capacity, inlet water quality, outlet standard, project location and site layout for technical evaluation and quotation.
