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. The adsorption process is endothermic with a maximum adsorption of 83 percent at 30 o C for an … that acid-activated coconut shell carbon had higher adsorption for organic matter expressed as chemical oxygen demand, (COD), than barium chloride-activated coconut shell carbon and Calgon carbon (F-300) at all carbon dosages used. However, using spent coconut husks can be a cheap, environmentally friendly alternative source of AC for removing nitrogen and phosphorus in the secondary effluent.

Adsorption of heavy metal on the solid surfaces is an important technique to remove them from the industrial wastewaters. 5 0 obj The … recognized as an economical and efficient tool for wastewater treatment [7-9]. This study deals with the removal of residual pollutants from tanning wastewater by continuous adsorption mechanism, using local sand as a low-cost adsorbent. Waste water was treated with activated carbon prepared from coconut shell for a period of 5 minutes, 30 minutes and 60 minutes. The structure of activated carbon has a very large surface area -1 lb of granular activated carbon has the surface area of 125 acres. … Ayub S , Khorasgani F.Changani; Author Affiliations . 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. This study considered thermal and non-thermal, chemical activation methods to create four different AC treatments. The process should not be pose new problem for industry. conventional wastewater treatment plant (Olafadehan and Aribike, 2000). 1. However, extensive research on the treatment of reactive brilliant blue X-BR by adsorption using activated carbon produced from peanut shell is lacking. Keywords: Adsorption, coconut shell , waste water Introduction Organic pollution is the term used when large quantities of organic compounds. However, the adsorption preceded by the Fenton process has been proven to be highly efficient at removing contaminants. rpl�%d�y�C�b�����B��۹�z�6N� 7��5�t�ީ"��eB����h/��Sj0!�v5~�@���_n���x Introduction Pharmaceutical Industrial waste water streams are emerging contaminants in the aquatic environment and they are adversely affecting aquatic life and humans. �ڣ��{:�b-j�"�� ڿ��q�d���yE��PϹ�h ���)/d��˫at�cZ��?z)��G7R�����P.���^����; �lH8�;yq]ATLY�O١�/�9�j��R��V���+~�%x��q����乇�N���u�-@`a?�К{��ʜ�;�Y>v�U'п�`\��$���S} G� Z�Xi�6YI4*go�Ǹ���yZUX�y�b^���V�F�ʵ����n������%w)��an����9!�h�>\冈],��sR�|��]�+�� AO�z_��bK�z%`���gtx���)$N��̝>��{t|U#v9-�A�@t��Ċ���~�.MN��]��0V� x��}��q��y��og��Vwu�M�?\�2)Y�E�� ���"0�Ѓ�I��nY�Y���s �&����u��/���ӡ�s�������ů�[��^��j�y��Ûg���Ÿ,ݶ͇��;��0�������_]�6}9;�&0�Z���/~�X���~�Ϗ^��7���u��O݈�m�8��0�c���b�ÃW?\���n�{;_~wum���y�|rum��h.�^�n�j��qZ/o����7��#~�ܿI������οy�+��?Cc/��n��E�P�i��_���^�]?o����^�G��v�|�U��O]���:�M��E+�?���͸ɲ�@\8;����Z�q��������G�����0ƺyx:y����~S{�~��}���d?C���WԿ?����wÐ�尘n��f|�Ϟ;��u��;�M���?E���U�ý�LB#�8�����2�J3���Q���c�F�[Fk�x��U����s����a�&'%��/q��2�C�5���uyR�+3�i��ܾqǪgZ/���_^]O�)�J�ڄWW���4��ݼ 5�--W?����S6���W4��c0xu5,����p�& 4`P5�y�a�469�0O��r�m�6iƾ�kn�P�擟�nZz��7���$;Mݰ�y�5{��1��0�D�~g+��K��� -�66��h�������l�5v���Nhp��:�p��V�щ#��o���ɵ�M�ys�1{��+�-!aںytu\]�F9�[��=(�\�31 The extant of removal was found to be dependent on pH, contact time, adsorbent dose, concentration of metal and particle size. 1 CivilEngineering Department Z.H.
