Engineered MBBR Sewage Treatment Solutions for Industrial & Institutional Applications
Plizma Technology designs, manufactures, and executes MBBR-based Sewage Treatment Plants as an MBBR sewage treatment plant manufacturer and MBBR STP manufacturer and service provider for industrial, commercial, and institutional applications across India and neighbouring countries. Every system is engineered after influent assessment and load study, aligned with CPCB / SPCB discharge or reuse norms as a CPCB compliant MBBR sewage treatment plant and SPCB approved MBBR STP system. The focus stays on predictable on-site performance, not drawing-based assumptions.
The MBBR process is configured to manage fluctuating loads in an industrial MBBR sewage treatment plant by keeping biofilm loading conservative, hydraulics practical, and aeration sized for peak oxygen demand. Where reuse is required, secondary treatment is stabilised first and tertiary polishing is added only where genuinely needed. Plants are commissioned and performance-validated in line with CPCB norms under normal and peak load conditions.
Execution strength remains strong in Eastern India as an MBBR sewage treatment plant Eastern India specialist, with projects across West Bengal, Odisha, Jharkhand, Bihar, Chhattisgarh, and the North-Eastern states. This regional experience helps account for local regulations, load variability, and real site constraints under an SPCB approved MBBR STP system.
MBBR Sewage Treatment Plant – Design Basis & Execution
Plizma Technology designs and executes industrial MBBR Sewage Treatment Plants as compliance-driven process systems, engineered to meet CPCB and respective State Pollution Control Board discharge or reuse standards. Our plants are designed for continuous operation under variable hydraulic and organic loading conditions typical of industrial facilities, with long-term O&M support for MBBR plants.
The MBBR process design is based on detailed influent characterization, including average and peak flow, BOD, COD, TSS, oil & grease, and nutrient load, as part of an attached growth biological sewage treatment system. Reactor volumes are calculated using required organic loading rates and effective biofilm surface area, with optimized media type and fill fraction to ensure stable attached biomass development. Aeration systems are designed to meet process oxygen demand and mixing requirements while maintaining energy efficiency and operational reliability, supported by long-term O&M support for MBBR plants.
Downstream clarification, filtration, and tertiary treatment units are engineered based on treated water reuse or discharge criteria within the attached growth biological sewage treatment system framework. Sludge generation rates are evaluated at the design stage to ensure adequate sludge handling, thickening, and dewatering provisions with minimal operational intervention and structured long-term O&M support for MBBR plants.
How Does Our MBBR Sewage Treatment Plant Work?
An MBBR Sewage Treatment Plant works on an attached-growth biological concept, where partially treated sewage enters an aeration tank filled with floating bio-carrier media made from high-density polyethylene, supported by turnkey MBBR STP project company execution and MBBR STP operation and maintenance support. These carriers usually occupy around 40–60% of the reactor volume, moving freely inside the tank. Their job is simple but critical, they offer a very large protected surface area where microorganisms grow as biofilm and stay retained even when load keeps changing. This attached biomass allows efficient breakdown of organic pollutants, giving consistent BOD and COD reduction, while also supporting nitrification when dissolved oxygen is maintained properly.
Aeration inside the reactor serves two purposes at once, it keeps the media in constant motion and supplies oxygen required for aerobic biological reactions. As the biofilm grows thicker, excess biomass naturally shears off due to media movement, which keeps the system balanced without any need for sludge recirculation. The biologically treated wastewater then flows into a secondary clarifier, where the detached solids settle by gravity. Clear treated water moves forward for discharge or reuse treatment, while low sludge generation, stable performance, and tolerance to hydraulic or organic load variations make MBBR systems especially suitable for compact sites and space-limited installations.
Sewage Inlet to MBBR Reactor
Pretreated sewage enters the aeration reactor after screening and grit removal, ensuring stable hydraulic conditions inside the tank.
Aeration Tank with Bio-Carrier Media
The reactor contains HDPE bio-carrier media occupying about 40–60% of tank volume, moving freely and providing large protected surface area for biofilm growth.
Biological Treatment (BOD, COD & Nitrification)
Microorganisms attached on the media biodegrade organic matter under controlled aeration, achieving consistent BOD and COD reduction and supporting nitrification.
Natural Biofilm Shearing & Process Stability
Continuous aeration keeps media in motion, excess biomass shears off naturally, maintaining biological balance without sludge recirculation.
Secondary Clarification & Effluent Outlet
Treated wastewater flows to the secondary clarifier where solids settle by gravity, producing clear effluent suitable for discharge or further reuse treatment.
