4 Signs You Need To Replace Your Oil Separator

Oil separators, commonly used in industrial and commercial settings where oil is present in wastewater, work by allowing the oil and water mixture to flow into a chamber before entering the sewer. The oil/water mixture is slowed down, allowing the oil to rise to the surface before being removed from the top of the chamber, while clean water is discharged from the bottom. To meet regulatory standards, the separated oil should be properly disposed of. Ongoing maintenance of oil separators is extremely important to ensure the effectiveness in preventing environmental pollution, but sometimes an oil separator may need to be replaced entirely. Here are some signs to look out for.

Increased Oil Content in Discharged Water

If the discharged water from your separator has an increased oil content, this may be a sign that the separator is no longer working effectively. Whilst checking the separator for any visible damage, you should also ensure the inlet and outlet pipes are clear and unobstructed. After cleaning the oil separator, if you continue to notice oil content in the discharged water, it may be time to consider replacing the unit.

Frequent Clogs

If you experience frequent clogs or backups in your oil separator, this could be a sign it is not working properly. Not only do the separators remove oil from wastewater, they also remove any larger solids. If these are left to build up over time, you may end up with a clog or blockage. Your first action should be to clear the oil separator and surrounding pipes to encourage wastewater to flow again. However, if the issue persists it may be time to replace the oil separator.

Leaking or Damage

If you notice any leaks or damage to your oil separator, it may be time for a replacement. A damaged separator can lead to oil and other pollutants entering the environment, having serious consequences. If the oil separator cannot be repaired, or is nearing the end of its life, replacement may be the best option. In the event the separator has already leaked and contaminated the water, you should contact your local regulatory body and inform them of this and your plan to replace.

Corrosion or Rust

Metal oil separators are prone to corrosion and rust over time, weakening the structure and leading to leaking. Aline Pumps’ Kwikflo Oil Separator systems are made with chemical resistant, UV stabilised polyethylene and, under normal operating conditions, only requires the regular cleaning of the plate packs with hot water.


With proper maintenance and regular inspections oil separators can continue to work effectively throughout their life. Sometimes, however, a replacement may be the best option.
