Oil water separator does just what you might expect from the name it separates oil and suspended solids from water so that it can be skimmed away.
Oil is lighter than water so it tends to float to the top. However, because of the nature of wastewater, which is suffused with all kinds of contaminants, some oil particulates, especially tiny droplets, can get hung up.
Oil water separators are designed specifically to target oil based on the gravity difference between oil and water, allowing for heavier solids (sludge) to settle to the bottom while oil rises to the top, leaving additional wastewater in the middle layer. Sludge can then be scraped away, oil can be skimmed off the top and wastewater can move along for further treatment.
Why Separate Oil and Water?
What is the problem with oil? Why does it need to be separated from water? Simply put, it can pose an environmental hazard.
Oils found in wastewater can include not only the cooking oils and grease that homes, restaurants and other commercial interests wash down the drain, but also petroleum and other hazardous products. These can disrupt ecological systems and prove harmful to plants, animals and even humans.
If it can clog your pipes, it can definitely harm the environment. This is why we separate it out from wastewater
