Adsorption of heavy metal on the solid surfaces is an important technique to remove them from the industrial wastewaters. conventional wastewater treatment plant (Olafadehan and Aribike, 2000). Sorry, preview is currently unavailable. However, its widespread use in wastewater treatment … Adsorption is a wastewater purification technique for removing a wide range of compounds from industrial wastewater. So that it will not be affect environment & ecosystem. Adsorption takes place when molecules in a liquid bind themselves to the surface of a solid substance.

The adsorption follows a first order kinetics. The activated carbon surface is non-polar which results in an affinity for non-polar adsorbates such as organics. 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. Chemical activation was carried out using phosphoric acid (H3PO4). The adsorption performance of batch and fixed bed adsorption systems were investigated. Thus, the present work aimed to fill this research gap. Key words: Batch adsorption, heavy metals, wastewater, coconut husk. @�� �%�b��Ga���ͯ�q�� 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. INTRODUCTION Increased use of metals and chemicals in process industries has resulted in generation of large quantities of effluent that contain high level of toxic heavy metals and their presence pose environmental-disposal problems adsorption process of 2,4,6-trichlorophenol in wastewater using coconut shell-activated carbon,11 and found that Langmuir model could describe the process of adsorption on coconut shell-activated carbon. 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]. ACTF employed as an adsorbent to separate emulsified condensate oil from synthetic produced water as a treatment process before reinjection in oil reservoirs. This study considered thermal and non-thermal, chemical activation methods to create four different AC treatments. rpl�%d�y�C�b�����B��۹�z�6N� 7��5�t�ީ"��eB����h/��Sj0!�v5~�@���_n���x To browse Academia.edu and the wider internet faster and more securely, please take a few seconds to upgrade your browser. the adsorption processes. Textile, printing, and other related industries are facing problems of treatment and disposal of dye wastewater. The extant of removal was found to be dependent on pH, contact time, adsorbent dose, concentration of metal and particle size. The activation temperatures were selected at the range of 200–300 °C. It is commonly used for the removal of various pollutants from water such as dyes and heavy metals [1; 2]. 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.

In the present study, organic waste materials, like coconut shell, orange peels, and banana peels were used to produce activated carbon. The activated carbon (coconuts and groundnut shells) were cut into pieces in a furnace at a temperature of 450°C then crushed and sieved using different mesh sizes and activated using hydrochloric acid of different concentration. Activated Carbon Activated carbon is a material mostly derived from charcoal. Ayub S , Khorasgani F.Changani; Author Affiliations . 4000, Ogbomoso, Nigeria. Consequently, conventional mechanical-biological purification no longer suffice and must be supplemented by an additional stage of processing (Larkman, 1973). The needs to -identify the most effective and suitable characteristics of activated carbon are important because it defines the best alternative and at the same its efficiency in wastewater treatment. <> College, Faculty of Engineering and Technology.

This research is studying ammonia concentration, COD, alkalinity, VFA, ammonia removal and COD removal after incubation 7 days. Thus, peanut shell can be used to prepare activated carbon for wastewater treatment. Space requirement for the process should be as less as possible & without much infrastructure requirement. The extant of removal was found to be dependent on pH, contact time, adsorbent dose, concentration of metal and particle size. Adsorption has advantages over the other methods because of simple design and can involve low investment in term of both initial cost and land required. The food colors (sunset yellow and tartrazine) was prepared with … Treatment for 5 minutes was not enough for the effective removal of dissolved solids. This report was based on the comparative study on effectiveness of adsorption of food colors using coconuts and groundnut shell.

Adsorption is by far the most effective and widely used technique for the removal of toxic heavy metals from wastewater[5]. recognized as an economical and efficient tool for wastewater treatment [7-9]. However, using spent coconut husks can be a cheap, environmentally friendly alternative source of AC for removing nitrogen and phosphorus in the secondary effluent. The adsorption process is widely used for treatment of industrial wastewa‐ ter from organic and inorganic pollutants and meet the great attention from the researchers. The process should not be pose new problem for industry. Batch adsorption studies has been conducted by adding certain amount of activated carbon (Corncobs and Coconut Shell) 1g into 250 mL Erlenmeyer flasks containing 100 mL of different Adsorption is most commonly implemented for the removal or low concentrations of non-degradable organic compounds from groundwater, drinking water preparation, process water or as tertiary cleansing after, for example, biological water purification. Basically the test was conducted on Corncob and Coconut Shell to compare their effectiveness in the treatment of oil refinery wastewater. �Ή�dV�ߖ4����0�a��K�5�x�Z�g�.�“��5V���f7oG���;��'�Ӳn�ᷞl'�xZͿ6�6˺� �������|����:_\ � Activated carbon is … A.M.U.,Aligarh.
