Oil-Water Separator

Helping you to meet your environmental compliance responsibilities

The Water Resources Act 1991 strictly prohibits the discharge of noxious waste into the water cycle and doing so carries a maximum fine of £20,000.


Compressed air contains a high volume of vaporised water, which cools to form a liquid condensate consisting of a mixture of dirty, oily water. This oily condensate is classified as hazardous industrial waste and therefore must be disposed of responsibly i.e., either collected by a licenced waste removal company or treated at source prior to disposal.


Unfortunately, waste disposal can be expensive as it is charged by volume. By installing an oil/water separator however, it is possible to remove residual oil from your compressor condensate, allowing you to safely discharge the cleaned waste into a sewage drain. This process also helps you to reduce your reliance on external providers, giving you greater control and reliability.


There are various techniques that are used to separate the oil from the water in compressed air condensate including adsorption, absorption, and gravitational and mechanical separation. Whichever method is used, oil/water separators (OWS) are simple to install, easy to maintain and are a cost-effective way of meeting your waste management obligations. BCAS Ltd can help you find the correct one.
