Oil Water Separators – Extracting Oil From Water Automatically
Oil Water Separators are an extremely valuable and effective tool in removing oils, hydraulic fluids, fuels or petroleum based products from water. They usually have no moving parts and work on the simple fact that oil floats on water.
An oil water separator is a device that is designed to remove oil and solids from water to prevent damage to the environment.
Its operation is based on the difference between the weight of oil and the weight of water. Engineers and scientists call this weight of oil per specific amount of volume, specific gravity.
When an oil water separator is operating properly the oil will rise to the top, the wastewater will be in the middle and the solids will be on the bottom. The oil is skimmed off the top and reclaimed or reprocessed, the solids are scraped off the bottom and the wastewater is sent to a treatment center for final treatment.
The key to separating oil from wastewater is increasing the size of the oil droplets. The larger the oil droplet, the faster it will rise to the surface and the more oil can be removed.
There are several ways to increase the size of the droplets, but the most common is letting gravity act on the oil naturally. The problem is that because of movement of the oil droplets through the water, some of them develop a static charge that repels other droplets.
In order to prevent the build-up of these repelling static charges, the speed of the wastewater flowing through the separator must be cbd oil canada restricted to 3 feet per minute.
There are other things that keep the oil water separator from being the best solution to cleaning up oil and petroleum based spills from the wastewater surface.
For example, the typical oil water separator will not remove oil that is suspended in wastewater so it needs to be treated one more time before being released to the environment or into the sewer system.
When oil is suspended in wastewater or salt water, it is very difficult to remove quickly and effectively. The process is much more complicated, expensive and time consuming.
For this site, we’ll focus on the common types of oil water separators available for the majority of people who need to get one.
There are many different types of separators in use today, but the most common are gravity type separators and collecting (or coalescing) plate separators.
Gravity type separators rely on the fact that oil floats on wastewater as the basis for how they operate. The wastewater/oil mix is put into a tank that is wide enough, long enough and deep enough to provide a wide, quiet spot in the tank where oil can rise to the surface to be collected and removed.
