Impact/Purpose:
Water/Waste water Treatment
Description:
The potential emerging pollutants (PEPs) including hazardous chemicals, toxic metals, bio-wastes, etc., pose a severe threat to the human health, hygiene and ecology by way of polluting the environment and water sources. These pollutants may have been originated from the industrial effluent discharges from chemical factories, pharmaceutical, food and metal processing industries. When these PEPs mix in water sources, they pollute the water, thereby disturbing the benign environment. Considerable efforts have been made to alleviate the environmental pollution, but the crisis still exists due to the non-availability of appropriate methods of treatment. Innumerable methods have been developed for the treatment of effluents to separate the toxic chemicals/metals. Of these, membrane-based separation processes (MBSPs) employed to address the separation of toxic PEPs are proven to be quite effective as compared to conventional techniques to produce clean water from the waste streams at an affordable cost, using minimum energy. These methods have been widely explored to achieve an efficient separation of PEPs. Among the many MBSPs used, microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), forward osmosis (FO) and some judicially chosen hybrid technologies are widely employed. This review attempts to address the advantages and application potential of MBSPs over the conventional effluent treatment methods. The data compiled from various laboratories over the past decade are critically discussed and the review provides in-depth analysis as well as plausible solutions to the environmental pollution issues.
