PEMBUATAN ALAT PEMISAH MINYAK DENGAN AIR MENGGUNAKAN METODE ROTARY DISC

In the industrial world, waste has kind of diverse, whether it be oil, dirt, waste, or water. Therefore, the waste is important to be handled because it can damage the ecosystem in the water and the surrounding environment. In this case, the writer specializing in the treatment of waste water from industry. As known, industrial activity is very high and it causes a lot of waste. Waste water characteristics of these activities contains high suspended solids and oil. Until now, there are some tools that can process the waste properly, such as Dissolved Air Floatation (DAF) and Belt Press. But these tools become less effective when the waste water treatment containing oil because it will make the chemical process in the DAF to be imperfect. Basically, the working principle of the oil separator is the difference in specific gravity. The density of water is greater than the density of the oil, so the water will be at the bottom and the oil will be at the top when the separation occurs, then the oil that have been collected will be distributed or disposed to the sludge tank. To improve the efficiency, effectiveness, and eliminate the negative effects, the authors designed this machine to separate waste oil from waste water by Rotary disc method. From the results of manufacturing, oil and water separator can function as expected and effective when used. The water that comes out through the machine is not mix with the oil and the result is environmental friendly
