MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611010244 A) filed by Trinity International, New Delhi, on Jan. 31, for 'system and method for phycoremediation of tannery wastewater effluent with low sludge generation.'
Inventor(s) include Sukhdev Singh; Sapan Anand; Haleema Naaz; and Piyush Parkhey.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an algal-based system and method (100) for treating chromium-containing tannery effluent and enabling safe discharge and reuse. The method comprises subjecting raw tannery effluent to pre-treatment using alum and lime to obtain a clarified effluent (101). The clarified effluent is then subjected to sequential biological treatment by dosing with a first algal culture (102), a second algal culture (103), a third algal culture (104), and a fourth algal culture (105), each at progressively reduced volumetric concentrations and increased retention times to enhance chromium uptake and stabilization. Following algal treatment, algal biomass is separated to obtain treated effluent (106). The treated effluent (107) exhibits significant reductions in total chromium, total dissolved solids, and chemical oxygen demand, with improved pH and color, and is suitable for discharge or reuse in tanning processes. The separated algal biomass (108) is enriched with sequestered chromium and is suitable for use as a fertilizer or soil conditioner. The invention provides an efficient, low-sludge, and environmentally sustainable solution for tannery effluent management."
