Title : Nanoremediation of wastewater using membrane filtration technology
Abstract:
Common Effluent Treatment Plant (CETP) concept has been developed for the treatment of industrial wastewater employing pre-treatment, primary-secondary and tertiary methods to comply with the regulatory standards of discharge. However, the treated effluent discharges into the water-soil environment have been found to contain persistent organic and inorganic pollutants.
Nano-based Membrane Filtration Technology has been developed via microfiltration-ultrafiltration-nanofiltration for the remediation of wastewater contaminants using cellulose based nano filter placed in each reactor having different pore size as per designed membrane. Membrane reactors are placed vertically one below the other on stainless steel stand. Each membrane reactor has a provision of interaction with the membrane’s porous material, filtration/collection system and passing into another membrane reactor by pressure driven methods for the remediation viz. microfiltration-ultrafiltration-nanofiltration. A membrane is a thin film of porous material that allows water molecules to interact and pass through the pressure-driven system. The membrane nanofilm reactor is an emerging technology for water and wastewater treatment. A recent research study CETP wastewater treatment demonstrated by M H Fulekar and Ashita Rai have efficient and effective treatment and purification significantly faster than other advanced wastewater treatment technologies.
