Solar-powered membrane filtration device and water purification system.

Abstract

The present invention relates to ጸ solar-powered membrane filtration device for water purification, comprising a solar energy generation unit, solar battery, pump, a water-feed reservoir, a membrane filtration module, water hose, pre-filtration module, treated-water collection tank, and purified water dispenser. The solar energy generation unit supplies electrical energy directly and / or through the energy storage unit to operate the pump, which facilitates water transport from the feed reservoir through the membrane filtration module. The membrane module [5 configured to receive a replaceable or removable membrane element and to direct feed water across or through the membrane while separating contaminants from the purified-water stream. The system further provides controlled water flow and pressure through appropriate flow-management components. In preferred embodiments, the membrane filtration module contains a photocatalytic membrane, comprising ዉ CNF / gO / WOas-incorporated polyether sulfone membrane. The device 18 configured for decentralized and off-grid water purification and may be scaled for household, institutional, community and rural applications.
