Oil Separator Tanks

Most machines operate by separating oil and water based on the principle of gravity displacement, utilising gravity plates, centrifugal force, flotation and other methods. They do this to separate oil and water, so that the water can be treated for discharge into sewers.

Oil and water separators are used in many and varied industries, from crude oil production to vegetable and mineral oil manufacturing. Automotive workshops, car washes, mining and foood manufacturing businesses are just some – oil separator tanks are even used on ships to prevent oil and other contaminants from reaching the ocean.

Regular oil water separator waste management includes servicing your tank every three to six months, depending on type and volume. Wanless can remove accumulated waste from the tank, followed by a deep service clean. Depending on your location and industry, your waste oil water separator tank may also be regulated by water authorities, making regular service essential.

Our vision goes deeper than recycling

A staggering 9 million tonnes of plastic ends up in the world’s oceans each year, and land-based waste is the greatest polluter. This ocean debris affects about 700 marine species, some of which are now endangered.

To help turn the tide on plastic pollution, Wanless eco(logical) is investing in US’s oceans.
