Integrated MBR wastewater treatment equipment is a highly efficient and environmentally friendly system that combines biological treatment with membrane separation. By utilizing Membrane Bioreactor (MBR) technology, it effectively removes suspended solids, organic pollutants, and microorganisms from wastewater while maintaining stable operation and low energy consumption.
Working Principle
The core technology of the system is the Membrane Bioreactor (MBR).
The process uses micro-porous membranes to filter the mixed liquor, retaining suspended solids and microorganisms on the membrane surface to achieve high-efficiency solid–liquid separation.
At the same time, microorganisms inside the bioreactor degrade and convert the organic pollutants, ensuring excellent effluent quality.
The working process is as follows:
Influent Pretreatment
Wastewater first enters the pretreatment section, where coarse screens and grit chambers remove large solids and inorganic sediments.
Biological Reaction Stage
Pre-treated wastewater flows into the bioreactor. Microorganisms degrade organic matter through aerobic biological processes.
Sludge Formation
Organic contaminants are converted and decomposed by microorganisms, generating biological sludge during the process.
Membrane Filtration
The mixture of water and sludge enters the membrane tank. Micro-porous membranes separate the clarified water from the mixed liquor, while solids
and biomass are fully retained in the reactor.
Disinfection and Reuse
The permeate, already clear and stable in quality, passes through a disinfection system. The treated water can be reused for irrigation, flushing, landscape water, or discharged safely.
Main Components of Integrated MBR Equipment
Screening and Grit Removal System
Removes coarse solids, fibers, sand, and other large particles to protect downstream units.
Bioreactor (Aeration & Biological Treatment Zone)
Equipped with an aeration system and biomass for effective degradation of organic pollutants.
Membrane Module
Consists of micro-porous membranes and membrane cassettes used to achieve high-efficiency solid–liquid separation.
Disinfection System
Ensures that the treated effluent meets reuse or discharge standards through UV or chemical disinfection.
Automatic Control System
Monitors and controls the entire treatment process, including aeration, membrane operation, pumps, sludge discharge, and safety alarms.
