Grease separators

Water is one of the most precious commodities of our earth. Effective and reliable treatment systems are required wherever there is a danger of its contamination. Fats and oils contained in wastewater have a very detrimental effect on the sewer system and on wastewater treatment and sludge treatment. Among other things, they cause clogging of grates, overgrowth of sewer walls, and corrosion of steel treatment plant components. Process wastewater containing higher than acceptable amounts of organic fats must be treated before being discharged into the sewer system.

Comparison of grease separators

Depending on the needs of your project: catchment area, type of facility, construction space or separator capacity, choose a separator made of concrete or plastic. The following comparison tool will help you decide which solution is most suitable for your project.

How do grease separators work?

PE separator

Vegetable and animal fat separators operate based on the principle of flotation and sedimentation of wastewater. The wastewater entering the separators generally contains other pollutants in addition to fat, such as:

  • Sand

  • Mineral or organic sediments

  • Other solids

Concrete separator

If the waste water entering the separator contains this type   of pollution, it is necessary to use a settling tank integrated into the separator or used as a separate device before the separator.

The settling tank slows down the flow of water, and as a result of the sedimentation process in the settling tank, the particles gravitationally denser than water settle to the bottom of the tank and are stored there. In the second phase of wastewater treatment, the phenomenon of flotation takes place, whereby grease particles, due to their density lower than that of water, accumulate on the surface of the water. The inlet and outlet are siphoned which prevents unpleasant odours from escaping from the unit.

Application areas for AQUAFIX grease separators

Fat separators are used in areas where one of the by-products of processing or production is fat. These include:
