Performance evaluation of surfactant removal by adsorption technique and its comparative studies with other existing treatment processes : A short review

摘要

Adsorption process has been found to be one of the oldest and finest treatment methods for surfactants removal. As the control of water pollution has become important in current years, the use of physical, chemical and biological treatment methods such as membrane filtration, ion-exchange, coagulation/flocculation and biological degradation have become more and more challenging in terms of cost and efficiency. Adsorption is a technique, which is extensively used for surfactant removal. In the present review, the focus is made on the adsorption process using low-cost materials, and it is compared with other techniques for surfactant remediation.
