MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202521057864 A) filed by Dkte Society's Textile And Engineering Institute; Dr. Mahesh Balasaheb Chougule; Mr. Ejazahmad M. Karimkhan; and Mr. Harshal Pandurang Bade, Ichalkaranji, Maharashtra, on June 16, for 'eco-friendly coagulation and multimedia filtration system for institutional kitchen wastewater treatment.'
Inventor(s) include Dr. Mahesh Balasaheb Chougule; Mr. Ejazahmad M. Karimkhan; and Mr. Harshal Pandurang Bade.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "Eco-Friendly Coagulation and Multimedia Filtration System for Institutional Kitchen Wastewater Treatment This invention describes an eco-friendly, gravity-operated institutional kitchen wastewater treatment system comprising a natural coagulation unit and a vertically aligned multimedia filtration assembly. The system utilizes plant-derived coagulants, specifically Moringa oleifera seed powder and banana pith powder, to destabilize and aggregate suspended and colloidal impurities through bio-flocculation. The clarified effluent is then conveyed via gravitational overflow into a stratified filtration column composed sequentially of coconut coir, coarse sand, activated carbon, fine sand, and aggregates. Each layer is engineered to target specific pollutant classes through physical entrapment, adsorption, and polishing. The integrated system effectively reduces turbidity, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), and microbial load. The treated water is rendered suitable for non-potable applications such as irrigation and sanitation. The invention provides a sustainable, low-cost, and energy-independent alternative to conventional chemical-based effluent treatment methods, particularly suited for decentralized institutional environments."
