The possibility of pretreating a complex tannery effluent heavily loaded with a natural material such as sand is significant. 1. The process should not be pose new problem for industry. Sanitary landfill leachates usually have characteristics that depend on the region where they are generated and according to the age of the landfill, which is why a unique treatment for their sanitation has not been found. The structure of activated carbon has a very large surface area -1 lb of granular activated carbon has the surface area of 125 acres. Adsorption is by far the most effective and widely used technique for the removal of toxic heavy metals from wastewater[5]. %�쏢 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 Chemical activation was carried out using phosphoric acid (H3PO4). 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. Mubarik et al. ACTF employed as an adsorbent to separate emulsified condensate oil from synthetic produced water as a treatment process before reinjection in oil reservoirs. 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. Adsorbents have a very high internal surf… 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. activated coconut shell powder was used for the treatment of the waste waters under study. Conventional wastewater treatment using activated carbon (AC) from charcoal is very costly. So that it will not be affect environment & ecosystem. The purpose of the present study is to evaluate the ability of agro-waste material coconut shell to remove Cr (VI) from wastewater. �rܪ���x�'��N3��F��W���\M#��g����-�LT�_N�^&��l{YYܬ�~���Kf�[XKt# Key words: Batch adsorption, heavy metals, wastewater, coconut husk.

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]. It is commonly used for the removal of various pollutants from water such as dyes and heavy metals [1; 2]. Adsorption of heavy metal on the solid surfaces is an important technique to remove them from the industrial wastewaters. ]l�B��s�h�A�US�2XI�ƀU�E�Y%j$�R��"� i�z ߔ���R��⫄lyWȢG�J�*������-� l�3P��� ��l9K} ���q���U>*c��᳤,WTC��/I����+b�W��Kt&��-�M�V� 1. However, using spent coconut husks can be a cheap, environmentally friendly alternative source of AC for removing nitrogen and phosphorus in the secondary effluent. Basically the test was conducted on Corncob and Coconut Shell to compare their effectiveness in the treatment of oil refinery wastewater. Thus, peanut shell can be used to prepare activated carbon for wastewater treatment. ganic contaminants in wastewater treatment. The extant of removal was found to be dependent on pH, contact time, adsorbent dose, concentration of metal and particle size. Adsorption experiments Removal of organic matter (COD) from the wastewaters with varying amounts of adsorbent (1-5g/100ml) was studied keeping pH (11.83) and agitation time (1h) constant. Thus, the potential for using agricultural waste (coconut The solutions were agitated for 1 h using a magnetic However, the adsorption preceded by the Fenton process has been proven to be highly efficient at removing contaminants.
