Removing oil from water is an important part of water treatment and is an essential step in allowing water to be safely released back in to the environment.

This self-paced course explains the industry standard methods of removing oil from oil-in-water mixtures. Different modes of oil presence in water are explained and the influence of these modes on how to remove the oil is detailed. The main unit operations for deoiling, such as API separators, Skim Tanks, flotation methods (Dissolved Gas Flotation, Dispersed Gas Flotation), Oil Removal Filters, Centrifuges, Hydrocyclones, Coalescers, and Demulsification methods are explained. Participants are shown the range of application of a given method, together with the advantages and disadvantages.

The course consists of 10 online modules based on video lectures. All training content is provided through your EngineeringTrainer account.

After the course you have unlimited access to the course for 1 year, including any new course material. This allows you to perform modules again should you need to refresh your knowledge for your projects.
