Detergent and Water Recovery from Laundry Wastewater Using Tilted Panel Membrane Filtration System

Abstract

Increasing global concern on clean water scarcity and environmental sustainability drive invention in water reclamation technology. Laundry wastewater reclamation via membrane technology faces the challenge of membrane fouling. This paper assesses a tilting-the-filtration-panel filtration system for the treatment of real laundry wastewater filtration aimed for water and detergent reuse. Results showed that the panel tilting significantly improved fouling control and enhanced permeability due to enhanced contact of air bubbles with the membrane surface, which induced continuous detachment of foulant from the membrane surface. The combination of aeration rate and tilting angle resulted in up to 83% permeability enhancement from 109 to 221.4 ± 10.8 (L/m2·h·bar). The system also offers 32% detergent recovery. Overall findings suggest that the system offers an attractive approach for both fouling management and detergent recovery and can potentially be applied under a simple setup in which filtration can be driven by gravity/hydrostatic pressure.

Effect of Membrane Materials and Operational Parameters on Performance and Energy Consumption of Oil/Water Emulsion Filtration

“…Those limitations hinder their continuous industrial implementation [ 7 , 8 ]. On the other hand, pressure-driven membrane-based technology has been explored for handling oil/water emulsion due to its economic and environmental advantages [ 5 , 9 , 10 ].…”

Membrane Filtration as Post-Treatment of Rotating Biological Contactor for Wastewater Treatment

“…For instance, the RBC/wetland configuration provides a storm flow buffer and improves the discharge effluent quality [7]. In previous studies, the application of membrane technology in combination with RBCs as a post-treatment helped to enhance effluent quality and removal efficiency [21,22].…”

Cellulose Acetate (CA) Membrane Tailored with Fe3O4@ZnO Core Shell Nanoparticles: Fabrication, Structural analysis and Its Adsorption Analysis

“…The major downside of the UF membrane is the fouling issues due to the foulants (water molecules and micro‐organism), which settles down on the surface of the membrane by continuing to form a cake layer of foulants and reduces the durability of the membrane.Disinfection of the membrane with an alkaline or acid/base solution will affect the lifespan of the membrane. Hence it is extremely necessary to optimize the antifouling properties and hydrophilic nature of the membrane [1, 14, 19, 20] …”

“…Hence it is extremely necessary to optimize the antifouling properties and hydrophilic nature of the membrane. [1,14,19,20] To get overcome the downside of the membranes, hydrophilic Nano-additives construct a novel material called "Nanocomposite". This is a combination of many more distinct organic and inorganic materials, which includes carbonate, silica, clay, activated carbon and metal oxides, which are blended with polymer membrane.…”
