Comparison of Membrane-Based Treatment Methods for the Removal of Micro-Pollutants from Reclaimed Water

Devaisy, S.; Kandasamy, J.; Nguyen, T.V.; Johir, M.A.H.; Ratnaweera, H.; Vigneswaran, S. (MDPI, 2022-11-16)

Dual membrane hybrid systems generally produce reclaimed water for non-potable uses by blending microfiltered biologically treated sewage effluent (BTSE) and reverse osmosis (RO) permeate. This reclaimed water is found to ...
Membranes in Water Reclamation: Treatment, Reuse and Concentrate Management

Devaisy, S.; Kandasamy, J.; Nguyen, T.V.; Ratnaweera, H.; Vigneswaran, S. (MDPI, 2023-06-15)

In this article, an extensive examination is provided on the possible uses of membranes and hybrid processes in wastewater treatment. While membrane technologies face certain constraints, such as membrane fouling and ...
Removal of Organics with Ion-Exchange Resins (IEX) from Reverse Osmosis Concentrate

Devaisy, S.; Kandasamy, J.; Aryal, R.; Johir, M.A.H.; Ratnaweera, H.; Vigneswaran, S. (MDPI, 2023-01-20)

Reverse osmosis concentrate (ROC) produced as the by-product of the reverse osmosis process consists of a high load of organics (macro and micro) that potentially cause eco-toxicological effects in the environment. Previous ...
