Abstract
The use of coconut shell based adsorbent for removing various pollutants from wastewater offers attractive advantages such as exceptional adsorption capacity with larger surface area, low-cost and biocompatibility for a wide range of pollutants. The same goes for calcium carbonate based adsorbent, which provides better removal for metals ions through precipitation method. In fact, recycling of waste material is considered environmentally preferable and is supported by public opinion and government policy. However, because of unit operations mechanisms and effectiveness are different to one another in downstream process, it is quite difficult to provide good adsorbent that exhibits dual attributes of hydrophobic and hydrophilic characters. This paper provides brief process for sintering of composite adsorbent for separation and purification of industrial wastewater application. Characterization was performed by physical and chemical approach. Results prove that the inclusion of biopolymer as composite binder improved mechanical properties of the composite adsorbent. � Published under licence by IOP Publishing Ltd.
