Flocculation and membrane filtration of stormwater - Laboratory experiments

Crossflow Filtration of Sodium Chloride Solution by A Polymeric Nanofilter: Minimization of Concentration Polarization by a Novel Backpulsing Method

In the present study, the production of low-salt water from salty water by nanofiltration as well as membrane fouling was investigated. Furthermore, a new method was proposed and tested experimentally for creating the backpulse in order to minimization of fouling and increase of the filtration efficiency. In the proposed method, the permeate was used instead of gas for creating the...

Laboratory Studies on Granular Filters and Their Relationship to Geotextiles for Stormwater Pollutant Reduction

Applications of geotextiles within tertiary stormwater treatment systems and for stormwater infiltration can provide a substrate for biofilm formation, enabling biological treatment of contaminants. Geotextiles can serve as an efficient part of stormwater filtration within the urban water environment. The project assessed the applications of three experimental granular filters as a sustainable ...

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

Development of Hybrid Ultrafiltration Combined with Both Flocculation and Adsorption Treatments for Advanced Removal of Humic Substances

Currently with the progression of the pollution in water sources, considerable attention has been given to the application of membrane filtration technology using microfiltration or ultrafiltration membranes to the surface water treatment as an alternative to conventional coagulation sedimentation and sand filtration. The microfiltration and ultrafiltration membranes are appropriate for complet...

ICUD-0539 Removal of small particles from urban snow melt mixture by coagulation/flocculation and sedimentation

This abstract presents a laboratory study of a coagulation/flocculation process on an urban snow melt mixture. Coagulation/flocculation is ubiquitous in water treatment, but has seen little use in the stormwater context. Using a jar-test procedure five different chemicals are evaluated as primary coagulants and their treatment performance on urban snow melt with respect to solids removal and me...
