granular amorphous peat, fly ash, peanut skin, and coconut husk hull. Zinc salts heavy doses (165 mg) in continuation causes vomiting, renal damage, and cramps. Discharge standard as per EPA and I:S for zinc is 5.0 mg/l. Zinc concentration was highest in site AB 4 (24 mg/l), least in site AB 1 (2.08 mg/l). Concentration in site AB 2 and AB 3 was 6.52mg/l and 14.2 mg/l respectively. Zinc in decreasing order of concentration was as follows: AB 4 >AB 3 >AB 2 >AB 1 . Nano filtration is effective membrane technology for the removal or separation of zinc in solution or waste waters. Suggested natural adsorbent for zinc adsorption are blast furnace slag, china clay waste tea leaves and cement matrix. Conclusion It is thus concluded that AB 1 waste water was alkaline , highly organically polluted indicated by high BOD and COD values and low in metal pollution, AB 2 site waste water was slightly acidic , highest in organic pollution, second lowest in metal pollution, AB 3 waste water sample was acidic , with highest metal pollution and low organic pollution. AB 4 site waste water was highly acidic, lowest in organic pollution, and second highest in metal pollution. In all these electroplating units, certainly there is a need to treat the waste water for certain heavy metals and for chemical and organic pollution before it discharges in to open drains. As these effluents from electroplating units are highly corrosive due to the presence of acids and toxic metals, there discharge directly in to rivers (Yamuna river in case of Agra) without neutralization decreases the pH of river water and results in mass mortality of aquatic culture. Certainly there is a need for scientific disposal of effluents, which to certain extent can be achieved by membrane technologies and adsorbents referred in the present paper. Beside * All values except pH are in mg/l this sincere execution of policies which restrict the effluent discharge exceeding the tolerance limits prescribed by IS: Standards, CPCB and EPA for discharge of industrial effluents is urgently needed in case of present industry.
