MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202521056083 A) filed by Rathod, Ajit P, Nagpur, Maharashtra, on June 11, for 'a method for preparing cow dung ash membranes for efficient methylene blue dye removal.'
Inventor(s) include Rathod, Ajit P; and Ramteke, Pradeep Kumar.
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: "The present invention relates to a method for preparing ceramic membranes using Cow Dung Ash (CDA) for the efficient removal of Methylene Blue (MB) dye from wastewater. The membranes are fabricated by blending 80 wt% cow dung ash (CDA), 5 wt% calcium carbonate (CaCO3), 5 wt% anhydrous sodium carbonate (Na2CO3), 7 wt% sodium silicate nonahydrate (Na2SiO3 9H2O), 3 wt% boric acid (H3BO3), and 1 ml of distilled water followed by hydraulic pressing, drying, and sintering at temperatures ranging from 700 C to 900 C. The resulting ceramic membranes exhibit high porosity, mechanical strength, and water permeability, making them effective for dye separation. Characterization techniques such as FTIR, XRD, SEM, and water flux analysis confirm the structural integrity and functional performance of the membranes. Experimental studies demonstrate that the membranes achieve up to 99.65% MB dye removal at optimal conditions, with sustainable performance over multiple cycles."
