In India the vehicles are increasing day by day , in these vehicle the maximum number is occupied by two wheelers at the same time the service center for maintains of these vehicles are also increases. The activities done in service center generate waste water which includes oil and grease. These oil and grease are organic matter and also biodegradable but it takes more time to naturally degrade and separate out from water. That oil forms a layer on surface of water. In STP there is skimming tank are provided to separate out the oil from water, but this method is also not suitable for longer time as the oil gets clogged in skimming tank and other units of STP. It is difficult to clean, maintain and to run the units. Hence there is need to remove the oil and grease at source itself. Adsorption technic is effective method for removal of oil and grease from source. Corn cobs are the agricultural waste material used for the adsorption technic. In this technic adsorbate are cobs. The experiment is carried out by considering different parameter 1) flow rate 2) dose 3) contact period 4) length of channel. The efficiency of removal of oil and grease is up to 70% to 80%.
