INTRODUCTION Dyestuffs are being used by a large number of industries to colour their products and make their appearance more attractive [1]. %PDF-1.4 activated coconut shell powder was used for the treatment of the waste waters under study. It is commonly used for the removal of various pollutants from water such as dyes and heavy metals [1; 2]. Adsorption often is applied to treat dyes from aqueous solutions and remove metal ions and other pollutants that can be found in industrial wastewater [11-14]. Modeling Of Adsorption Process In Wastewater Treatment Using Artificial Neural Network Mansoor Kazemimoghadam Malek Ashtar University of Technology, Tehran, Iran mzkazemi@gmail.com Abstract: Activated carbon is a common and popular adsorbent that has been extensively used in separation and purification processes due to its high adsorption capacity and high surface area. �-N���Z�j�⫱ſ���;�>��^s���=w�tO�"�NEI���Yw��7�E��QK]��t,[>�hx��7'@~[u�:����Y�j?�O�`�����j؂�%ۼd��0;d���FӍ�RD�D wastewater treatment Huifang Wu , Ruoya Chen, Haixia Du, Jia Zhang, Lumeng Shi, Yu Qin, Lingzhi Yue and Junping Wang Nanjing Tech University, China Abstract In this study, the adsorption capacities of peanut shell activated carbon samples prepared using three types of peanut shell as raw material were compared.

Adsorption is by far the most effective and widely used technique for the removal of toxic heavy metals from wastewater[5]. This study deals with the removal of residual pollutants from tanning wastewater by continuous adsorption mechanism, using local sand as a low-cost adsorbent. This research using dairy milk simulated waste water. Adsorption is a wastewater purification technique for removing a wide range of compounds from industrial wastewater. In the present study, organic waste materials, like coconut shell, orange peels, and banana peels were used to produce activated carbon. The … The adsorption follows a first order kinetics. In wastewater treatment plants (WWTPs), adsorption processes are applied for the removal of dissolved pollutants that remain from the subsequent biological phases or after chemical oxidation treatments. Space requirement for the process should be as less as possible & without much infrastructure requirement. The purpose of the present study is to evaluate the ability of agro-waste material coconut shell to remove Cr (VI) from However, using spent coconut husks can be a cheap, environmentally friendly alternative source of AC for removing nitrogen and phosphorus in the secondary effluent.
