Separators – for a clean environment

Water is one of our most precious resources and is not available in unlimited quantities. It is not always possible to avoid soiling within the context of numerous areas of application such as kitchens or vehicle refuelling, for example. For this reason, polluted wastewater must be pretreated and cleaned with the aid of appropriate separator systems before it is discharged to the public sewer system.

KESSEL offers a wide range of innovative plastic separators for different areas of application and wastewater quantities:

Grease Separators EasyClean - For A Clean Environment

In many commercial and industrial operations such as restaurants, hotels, motorway service areas, butchers or other food-processing plants, greases and oils get into the wastewater. This wastewater has quite a way to travel before it reaches the next sewage plant.

A great deal of grease and food residue can become deposited in the drainage system along the way, leading to pipe blockages, corrosion and odour formation as well as problems with the operation of sewage plants and lifting stations. For this reason, legislation requires plants which produce greasy wastewater to install grease separators according to EN 1825!

The whole KESSEL range of polyethylene grease separators fulfils all the legal requirements for various installation situations:

Grease separators for free-standing installation

Grease separator
  • Grease separator EasyClean free
    Grease separator EasyClean according to EN 1825 for free-standing installation inside buildings. Available in the nominal sizes NS 2 – NS 30.
  • Grease separator EasyClean ModularGrease separator for free-standing installation. Can be split for installation – ideal where access is tight. Available from NS 0,25 up to NS 4.

Grease separators for outdoor underground installation

Sediment separators, sand and sludge traps EasySink

Sediment separators are used to trap residue such as plaster, scale and clay. This is mainly the case at dentistry, surgical and orthopedic departments in hospitals and doctors’ practices.

The size of the sediment separator is dimensioned according to the volume and type of washwater to be discharged. The washwater drain, density of heavy materials and quantity of heavy materials to be discharged must be taken into account.

Sludge and sand traps are used wherever a lot of sludge, sand and/or soil occur, can enter the sewage system and lead to blockages. Possible areas of application are

  • Septic systems for wastewater treatment,
  • Rainwater management systems and
  • Gardening centres.

They are designed according to similar standards as with sediment separators. Depending on the dirt load, disposal should be carried out every one or two months.

The sediment separator and sludge traps can be supplied in any size for free-standing set-up or for underground installation.

Oil, Fuel and Coalescence Separators

Light liquid separators according to EN 858

Oil and coalescence separators are required where light liquids occur. This is usually at

  • Petrol / Gas stations,
  • Car washes,
  • Vehicle repair garages and
  • similar places.
  • With oil separators a special inlet system has a plug-flow effect in the separator. This slows the flow down and distributes it in a hydraulically effective way over the separator space. Whereas the heavy materials sink to the bottom and are separated out, the light materials rise to the top and are separated off there.

    With coalescence separators, a coalescence filter insert is installed before the drain to improve the separating effect in the separator. When the water flows through, tiny oil drops combine to form large drops which then leave the coalescence material.

    All light liquid separators are supplied for underground installation up to load class D. There are suitable sampling chambers and alarm equipment available in the range for all nominal sizes (available up to NS 20).

    Starch separators EasyStarch

    Starch is stored in the form of grains inside the cells of potatoes, cereals and other pulses. During the peeling/shelling process, the starch grains (cells) are torn open and the starch washed out by water. Potatoes have a starch content of around 20 – 30%. The wastewater produced then has a starch content of around 2 to 5% depending on processing technique. This leads to deposits and, after a short time to encrustation and blockages in the wastewater pipes.

    DIN 1986 prescribes the compulsory installation of a starch separator for wastewater containing starch. The most frequent areas of application are kitchen companies

    • Guesthouses,
    • Crisps and chips manufacturers,
    • As well as croquette manufacturers and tinning factories.

    The starch separators are supplied both for underground installation and for free-standing set-up with different disposal features.
