RMBR (Rotating Membrane Bio Reactor) is an advanced and energy-efficient wastewater treatment technology that combines biological treatment with continuously rotating membrane filtration. Used in modern STP and ETP systems, RMBR delivers crystal-clear treated water suitable for reuse in flushing, gardening, HVAC cooling, or industrial recycling.
1. What Is RMBR Technology?
RMBR is a membrane-based biological treatment process where the membrane modules rotate at a controlled speed to reduce fouling, increase oxygen transfer, and provide uninterrupted filtration. Unlike traditional MBR systems where fouling is high and cleaning is frequent, RMBR offers longer membrane life, lower energy consumption, and higher permeate quality. At SK Enviro Solutions, we design cutting-edge RMBR plants for high-rise residential towers, commercial complexes, hotels, hospitals, and industrial wastewater treatment where space-saving and high-quality output are essential.
2. How RMBR Works (Step-by-Step)
A) Screening & Primary Treatment: Incoming wastewater first passes through bar screens and chambers where floating solids, debris, hair, plastics, and grit are removed to protect downstream equipment.
B) Biological Aeration with Rotating Membrane System: Wastewater enters the aeration basin, where microorganisms break down BOD, COD, and organic pollutants. Inside the same basin, rotating membrane discs or cassettes continuously move, preventing sludge deposition and reducing fouling—one of the biggest advantages over traditional MBR.
C) Membrane Separation & Filtration: As the membranes rotate, treated water is pulled through ultra-fine pores (0.1–0.4 microns), ensuring removal of suspended solids, pathogens, bacteria, and turbidity. Filtration remains stable due to the self-cleaning effect of rotation.
D) Final Polishing & Disinfection: The filtered water undergoes tertiary polishing such as UV, ozone, or chlorination for safe reuse. The result is crystal-clear, odorless, and reusable water.
E) Sludge Handling & System Cycling: Excess sludge is periodically removed and sent for further dewatering. RMBR cycles continue automatically with PLC-based control—ensuring stable performance with minimal operator effort.
“RMBR offers the purity of MBR with lower fouling, less energy, and higher reliability—making it the future of premium wastewater treatment.”
3. Benefits of RMBR Technology
A) Superior Filtration Quality (Crystal Clear Water): RMBR produces water with extremely low turbidity due to fine membrane filtration—ideal for reuse applications.
B) Low Fouling Due to Rotation: Continuous rotation prevents solids from sticking to the membrane surface, reducing chemical cleaning frequency and increasing membrane lifespan.
C) Lower Energy Consumption: Compared to traditional MBR, RMBR uses optimized aeration and rotating motion, reducing blower and suction load significantly.
D) Compact & Space Efficient: RMBR units require less space due to integrated biological and membrane treatment, making them ideal for basements, rooftops & compact sites.
E) Long Membrane Life: The self-cleaning mechanism increases membrane durability, reducing O&M cost.
F) Stable Performance Under Load Variations: Even with fluctuating flow or pollutant load, RMBR maintains excellent treated water quality due to controlled biological and membrane processes.
