Design of Continuous Hybrid Wastewater Treatment System

In this study, a combination of different separation processes including adsorption, photocatalytic degradation and membrane filtration was used for wastewater treatment# for this purpose, activated carbon, cu2o/tio2 nanosheet containing 0#6 wt#% reduced graphene (cu2o/tio2/gr) and pan-based polymeric membrane were used as adsorbent, photocatalytic nanoparticles and nanofiltration respectively# nanofiltration membranes were fabricated by wet phase inversion method# pore diameter of the membrane by liquid-liquid displacement porosimetry (lldp), lldp results showed that the average pore size of the pure pan and pan/pvp hybrid membranes are and , which confirms that the fabricated membranes are in the nanofiltration range# separation properties of the hybrid processes were characterized by using iranian wood and paper plant (chuka) wastewater as feed solution# for this purpose, chuka wastewater was analyzed by spectroscopy, gravimetric and device analysis technique and their pollutants were detected# then wastewater was purified by using continuous hybrid processes containing adsorption, photocatalytic degradation and nanofiltration under 3 states# it was found that state 1 of hybrid processes (i#e# adsorption, photocatalytic degradation and membrane filtration) has the best separation performance for chuka wastewater treatments#
