Oily Water

Wastewater containing fats, oils and grease is classified as oily water. Oily water can be a result of wastewater from the oil and energy sector, the food and beverage industry as well as the mechanical industry. It can also be stormwater due to surface run-off containing grease deposits.

Removal of oil and suspended solids from the wastewater is the usual first stage of wastewater treatment. This is because oils in large quantities can cause biological treatments to fail as well as membrane and deionisation equipment to block. Wastewater treatment for oily water works on the basis that oil and water does not mix.

What is required

Local councils require industrial companies and commercial businesses such as car wash bays to remove fats, oils and grease through the use of oil and grease traps or triple interceptors as well as oil water separators (OWS) and hydro cyclones before the wastewater can be discharged into the sewerage system. For larger applications and as pre-treatment for decentralized wastewater treatment plants, the use of a dissolved air flotation (DAF) systems combines the efficient removal of oils and grease, as well as suspended solids.

Enviro Concepts, Oil Water Separator

Hydro cyclones use centrifugal force to separate the water from the oil. Oil Water Separator (OWS) use high surface area plate packs to coalesce emulsified oil droplets. DAF uses chemical coagulation and micro air bubbles to enhance oil, solids and water separation. After the removal of oil, the wastewater will require further treatment before it will meet the standards for discharge or recycle.
