WASTEWATER TREATMENT SYSTEM USING AIR INJECTION TYPE ULTRAFILTRATION TUBULAR MEMBRANE

摘要

PURPOSE: A wastewater treatment system using air injection type ultrafiltration tubular membrane is provided to promote flux velocity of membrane by preventing concentration polarization and membrane fouling. CONSTITUTION: In a wastewater treatment system including activated sludge process and ultrafiltration membrane, included are an ultrafiltration module(10) equipped with a plurality of tubular ultra-filtration membranes in cylindrical housing; a raw water pump(15) for supplying raw water to the ultrafiltration module; and an air injection device(70) installed at the inlet of raw water of ultrafiltration module.
