Tea factoy waste was collected in Axom Tea (OPC) Private Limited Assam, the annually production of tea is 450 tonnes. The amount of tea factory waste (TFW) production/ ann. after processing is 88 tonnes. an study has been carried out to investigated the feasibility of the use of TFW as an adsorbent for the removal of copper heavy metal. Many industries feed toxic heavy metals in the river during manufacturing of battery, cell etc. Batch adsorption studies have been carried out for evaluating the suitability of tea factory waste as a low cost adsorbent for removal of heavy metal (copper) from wastewaters. An Experimental setup is conduct by apply tea factory waste to wastewater as concentration (10 ppm), contact time (120 min), pH (4.5), adsorbent doses (1.2 gram) at room temperature. Maximum percentage removal of copper ions is 88 % at 4.5 pH, 120 contact times and 1.2 grams adsorbent.
