Chapter in book activated carbon for wastewater treatment

Watermelon has high amount of water. Thus, in Malaysia watermelon are easy to get and they are on seasonal fruit. From the peels itself, we will try to prepare and characterization activated carbon. Waste watermelon rind, a waste biomaterial, has not yet been evaluated as a raw material for the production of activated carbon using the chemical activation method by zinc chloride. So, for watermelon, as we know it contained high amount of water with promising levels of solid matters, which makes them even more appealing for the industrial manufacture of high-quality activated carbon. This unique usage of watermelon peels will not only reduce waste, but will also increase income for farmers and food processors, as well as lessen several negative environmental effects. Thus, the main objective of the present work was to evaluate the utility of waste watermelon rind as an abundant and accessible precursor for activated carbon production. The focus of this research is on determining the optimal conditions for pre-treatment of watermelon peel wastes in order to make them useful as adsorbents for contaminated waste from industrial effluents. The impact of operating parameters like carbonization temperature and time was investigated in this study. Some of the activated carbon treatment is a simple separation procedure. The activated carbon used in liquid phase applications is intended to have a large surface area and pore volume. It must also be sufficiently robust and abrasion resistant. In liquid phase applications, both powdered and granular activated carbon have been utilised.
