Today, all manufacturing companies need to minimize the effect of waste water in the farm and human health. It is depending on removing the oil and grease from the water. The Dr. Naganath Anna Nayakavadi H.K.A. Sugar factory placed Walwa. about E.T.P. section where worker removes oil manually and he told about scrap oil skimmer. Before scrap the oil skimmer it working but it problem when which is can not continuous remove oil from water and machine problem is that while the oil skimmer is not work properly Sum percentage of oil also goes on E.T.P section. When in the E.T.P they change the P.H value. They also effect on the farm. We have decided the make the arrangement at a time two oil skimmers run one motor.
The oil and grease contents in water effect on land as well as on the human being. Due to chemical present in waste, the water-lives are on the edge of destroying. Oil spillage problems mainly occur in the industries like oil are refineries, sugar factory and petrochemical industries etc. In the sugar factory spillage of oil mainly contribute from the mill section .daily 70-75 litres of oil per day is used for lubrication of heavy gears in every sugar factory in mill section. Whenever oil spills over water, it forms an emulsified layer. At the Effluent Treatment Plant (E.T.P.) in every sugar factory –recovery of oil is big problem as it seriously affects the quality of treated effluent water. Other than mill oil other types of oil are used. But they do not mix with gutter water because they are continuously circulated. This oil is used for following purpose. Turbine bearing, Febrile bearing, Gear box, Hydraulic system and continuous centrifugal m/batch type centrifugal m/c And Air compresso.This oil mix with wastewater only when they leak due to failure of oil seals, chocking of filter or any other reason.

The Dr.Naganath Anna Nayakavadi.H.K.A. sugar factory placed Walwa. about E.T.P. section where worker removes oil manually and he told about scrap oil skimmer. Before scrap the oil skimmer it working but it problem when which is used to remove oil but that machine can not continuous remove oil from water. They told us there is an “oil skimmer” but that machine problem occurs at the time scrap condition oil skimmer is continuous removing the oil. The problem is that while the oil skimmer is not work properly such as they cannot remove maximum percentage of the oil from water. Sum percentage of oil also goes on E.T.P section. When in the E.T.P they change the P.H value. They also effect on the farm. We have decided the make the arrangement at a time two oil skimmers run one motor.
II DESIGN OF MODIFED OIL SKIMMER MACHINE
A. Design of Shaft
Mainly shaft is used to mount and rotate the drum. Actually, there is very small driving load on the shaft. But weight of drum and licit tension will exert the force at the centre of shaft and thus there is tending moment on shaft. Therefore, we have designed the shaft for both bending and torsion.
1) The modified oil skimmer removes 630 liter/month oil from wastewater, and the existing machine was removed 360 lit/month.
2) It also helps to the factory economically. Total cost saved by using oil-skimming machine per season is 55,800 /- Rs
3) The PH of wastewater improved 5.4 to 6.1; it helps to control the water pollution.
4) It also prevents soil pollution in the agricultural field. If we drain this waste- water to agriculture, then there is no effect on soil.
