MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202311077220 A) filed by G. B. Pant University Of Agriculture & Technology, Pantnagar, Uttarakhand, on Nov. 13, 2023, for 'wastewater treatment through immobilized fungus and diatomaceous earth based formulation..'
Inventor(s) include Monika Chhimwal; and R. K. Srivastava.
The application for the patent was published on June 13, under issue no. 24/2025.
According to the abstract released by the Intellectual Property India: "Industrial wastewater has many toxic metals. Cadmium (Cd) is one of the major heavy metal found in wastewater releases from the battery manufacturing industries. Cd is highly toxic and has the potential to disturb the ecosystem. There is an advanced expensive wastewater treatment system available that can remove the toxic. metals from the wastewater before discharging it into the main river stream or for another beneficial purpose. To reduce the cost of secondary and tertiary wastewater treatment, there can be another step of pretreatment that is different from primary treatment. The presented formulation has Diatomaceous earth, Trichoderma harzianum Rifai, and Jakhiya extract waste that can be used for pretreatment purposes. The DE-based formulation can improve the wastewater quality by reducing the toxic Cd concentration through the process of adsorption by 80 to 81% at a dose of 800 mg/l. Along with that 800mg/l dose of formulation was able to reduce nitrate and phosphate by 51.7% and 60% respectively in 10 hours of retention time from the wastewater. The most positive point with this formulation is that the leftover residue after the adsorption purposes can be further used in building construction and cement industries. The proposed natural fungi-based formulation can handle wastewater at a primary stage and can use the pretreated wastewater for irrigation purposes."
