This is a very significant video, in which you will learn about the oil water separator cleaning. They are a sort of coalescing plates that are used in oil water separators. The oil is self-cleaning off the plates up to the surface of the water.
The oil that is collected in oily water separator is self-removing to the surface of the water because it slides up the underside of the plates. It then manages to come to the peaks, and then neatly forms a layer on top.
The best way to remove oil in the oil water separator cleaning is to use a vacuum truck if the size of the separator is big. However, if it is small, then all you need is a wet or dry vacuum. As a consequence, the solid particles land on top of the plates and then pass through the holes and then finally fall down. They then reach the bottom of the separator.
The oil can remove itself but the solid particles cannot. So, what happens sometimes is the separators become clogged with a large number of solids. To get rid of that, cleaning wands are used. It is a spray wand throws off water with a very high speed as it has 19 holes and a 6 inches globular spray. However, if they are plugged more than expected, then you can also take the plates out.
After taking the plates out, you can easily spray them with water at the surface for cleaning it and you are good to go.
