NextGen Sewage Treatment Plants with MBBR Technology – Achieving compact, efficient, and sustainable wastewater purification for high-quality reuse and regulatory compliance.
What It Does
Sarvo’s NextGen Sewage Treatment Plants leverage Moving Bed Biofilm Reactor MBBR) technology, a state-of-the-art biological treatment process designed for effective sewage and wastewater management in municipal, commercial, and industrial settings. MBBR operates by utilizing thousands of specialized polyethylene biofilm carriers that float freely within an aerated reactor tank. These carriers provide a large surface area for the growth of diverse microbial communities, including bacteria, fungi, and protozoa, which form a protective biofilm. As wastewater flows through the tank, the constant motion of the carriers—driven by aeration or mechanical mixing—ensures optimal contact between the pollutants and the biofilm. This facilitates the breakdown of organic matter, nutrients (like nitrogen and phosphorus), and contaminants through processes such as nitrification and denitrification.
Unlike traditional activated sludge systems, MBBR does not require sludge recycling, making it more resilient to shock loads, temperature fluctuations, and toxic inflows. The system integrates seamlessly with pre-treatment (e.g., screening and grit removal) and post-treatment (e.g., disinfection via UV or chlorination) stages, producing high-quality effluent suitable for reuse in irrigation, cooling, or non-potable applications. Sarvo’s implementation emphasizes low-energy aeration and modular design, allowing for easy scalability and retrofitting into existing plants.
This results in reduced sludge production, minimal chemical usage, and enhanced treatment efficiency, achieving over 95% removal of BOD and COD while complying with stringent environmental standards like those from India’s CPCB or international guidelines. Overall, it transforms sewage into a valuable resource, promoting water security and circular economy principles in water-stressed regions.
