Top MBBR Wastewater Treatment System Supplier | Custom OEM/ODM

As an mbbr wastewater treatment system supplier, Qingdao Jinwantong provides customized MBBR sewage treatment systems for projects that need compact layout, stable operation and flexible biological treatment performance. MBBR stands for Moving Bed Biofilm Reactor, a biofilm-based process using suspended carriers inside an aerated reactor. Microorganisms grow on the carrier surface and form active biofilm, which helps degrade organic pollutants in wastewater.

A complete MBBR wastewater treatment system usually includes pretreatment equipment, equalization tank, MBBR biological reactor, suspended biofilm media, aeration pipes or diffusers, blower, sedimentation tank or lamella clarifier, sludge discharge system, disinfection unit and electric control cabinet. According to actual wastewater conditions, the system can also be combined with DAF dissolved air flotation machines, CPI oil water separators, automatic dosing systems, filtration units or sludge dewatering equipment.

The basic process flow is:

Before wastewater enters the MBBR reactor, large solids and floating materials should be removed by a mechanical grille or screen. Equalization helps balance flow rate and pollutant concentration, reducing the risk of shock loading. In the MBBR reactor, aeration supplies oxygen and keeps the biofilm carriers moving. The biofilm contacts wastewater continuously and removes COD, BOD and, under proper design, ammonia nitrogen. After biological treatment, suspended solids and excess biofilm particles are separated through sedimentation or clarification.

For B2B buyers, choosing the right MBBR system is not only about daily capacity. Important selection factors include peak flow, inlet COD, BOD, SS, ammonia nitrogen, oil content, pH, temperature, discharge standard, available installation space, automation requirements and local operating conditions. For industrial wastewater, pretreatment may be necessary if the influent contains oil, grease, toxic chemicals, high salinity or high suspended solids.

MBBR systems are widely used in domestic sewage treatment, decentralized wastewater projects, small municipal sewage plants, hotels, schools, hospitals, residential communities, factories and construction camps. They are also suitable for upgrading existing biological treatment systems where additional treatment capacity is needed but site space is limited.
Qingdao Jinwantong can provide single MBBR equipment or complete wastewater treatment systems according to project requirements. To get a suitable proposal, customers can share the wastewater source, treatment capacity, inlet water quality, required outlet standard, project location and site layout. Our team will help evaluate the process configuration and provide practical equipment selection support.
