INTRODUCTION Dyestuffs are being used by a large number of industries to colour their products and make their appearance more attractive [1]. Conventional wastewater treatment using activated carbon (AC) from charcoal is very costly. The purpose of the present study is to evaluate the ability of agro-waste material coconut shell to remove Cr (VI) from wastewater. ACTF employed as an adsorbent to separate emulsified condensate oil from synthetic produced water as a treatment process before reinjection in oil reservoirs. Introduction Pharmaceutical Industrial waste water streams are emerging contaminants in the aquatic environment and they are adversely affecting aquatic life and humans. 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. Thus, the present work aimed to fill this research gap. Today, the most commonly adopted adsorbent is the activated carbon. rpl�%d�y�C�b�����B��۹�z�6N�

The adsorption experiments showed that the adsorption temperature, contact time, initial pH, and the adsorbent dosage had a great influence on the adsorption performance of diesel oil by crab shell biochar, and optimal experimental conditions were: temperature = 30 °C, adsorbate dosage = 0.2 g, pH = 7, contact time = 4 h. 2. (PDF) ADSORPTION PROCESS FOR WASTEWATER TREATMENT BY USING COCONUT SHELL | TJPRC Publication - Academia.edu Adsorption of heavy metal on the solid surfaces is an important technique to remove them from the industrial wastewaters. The characteristics of the acc powder is given in table 2. By using our site, you agree to our collection of information through the use of cookies. 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]. The activated carbon surface is non-polar which results in an affinity for non-polar adsorbates such as organics. The removal of reactive black and reactive yellow removal from aqueous solution is studied extensively [17], iron adsorption by coconuts and groundnut shell in a batch system: These studies indicate that) using diatomaceous Thus, peanut shell can be used to prepare activated carbon for wastewater treatment. 1. ��
