Low-cost multi-stage filtration enhanced by coagulation-flocculation in upflow gravel filtration

The effect of coupling coagulation and flocculation with membrane filtration in water treatment: a review.

Water supply and sanitation demands are foreseen to face enormous challenges over the coming decades to meet the fast growing needs in a global perspective. Significant growth in the industry is predicted and membrane separation technologies have been identified as one of the possible solutions to meet future demands. Application and implementation of membrane technology is expected both in pro...

Application of Hybrid Process of Coagulation/ Flocculation and Membrane Filtration to Water Treatment

Hydrocarbon contaminated water remediation using a locally constructed multi-stage bioreactor incorporated with media filtration

The present study investigated the coupling effect of biodegradation and media filtration in treating hydrocarbon contaminated water. The study recorded reductions in total petroleum hydrocarbon, total dissolved solids, turbidity and microbial load. The study was essentially a simulated pump and treat process that involved the pumping of hydrocarbon contaminated water for treatment in a locally...

Flocculation and membrane filtration of stormwater - Laboratory experiments

Stormwater run-off from for example industrial areas as well as roads with heavy traffic may contain considerable amounts of pollutants. Run-off from these areas may require special treatment to fully comply with existing environmental regulations and safeguard the receiving water bodies. In this study, flocculation and membrane filtration are tested to evaluate their efficacy in removing heavy...

Removal of Natural Organic Matter (NOM), Turbidity, and Color of surface water by integration of enhanced coagulation process and direct filtration

This work assesses the efficiency of integrated enhanced coagulation and direct filtration processes for the removal of color, turbidity, and natural organic matter (NOM) from surface water. The processes were conducted in a simulated pilot. The operating conditions of the treatment process, including pH, FeCl3 dose, and influent flow, were investigated. Following that, its efficienc...
