KLARO light fluid separator / oil separator
KLsepa.compact from NS3 to NS15
In facilities such as petrol stations, car washes or workshops where water can be contaminated by light mineral liquids, the use of separator systems is required by law. These systems ensure that the water is cleaned in an environmentally friendly manner so that it can be safely discharged into the wastewater system or a body of water, depending on the application.
With the KLsepa.compact, KLARO offers a practical solution: robust light fluid separators made of plastic containers. These are available both as System A (Class I) and System B (Class II) and meet the highest standards of efficiency and reliability.

Functionality
The KLARO light fluid separator
As the wastewater is slowed down to a lower flow velocity when it enters the separator, a natural separation process occurs as a result of the physical properties of the different substances. Oils and greases - also known as light liquids - are less dense than water and therefore rise to the water surface, where they combine to form a layer. Solids, on the other hand, are heavier and collect at the bottom of the tank.
This behavior can be observed with solids in any body of water and with oils whenever oil is added to water during cooking, for example. This is already the first step towards clear water, which is supported or optimized by KLARO technology in the further separation process to achieve an even higher cleaning performance.
Coalescence unit
The KLARO separator KLsepa.compact+ is a coalescence separator. This means that it is extended by a coalescence unit, which enables a significantly increased degree of separation. While the limit value to be achieved for the separation efficiency of a petrol separator is less than 100 mg residual oil per liter of water, this value can be reduced to less than 5 mg/l residual oil with the aid of a coalescence unit.

1st phase
In addition to easily separable oil droplets, very small oil droplets occur in a light liquid separator whose difference in density to water is too small to rise to the surface in the time available. They therefore remain in the draining water.

2nd phase
In order to also separate these smaller oil droplets, a material is placed in front of the drain to which the droplets adhere and form an oil film together.

3rd phase
As more oil is added, the thickness of the oil film increases until the adhesive capacity of the oil film is exceeded. Individual droplets are released, the size of which is sufficient to rise to the surface due to the difference in density and thus also be separated.
Our separators can be perfectly adapted to your individual requirements with high-quality accessories. Whether a reliable warning system for maximum safety, an external sampling shaft for easy sampling or versatile dome structures and covers - we offer you the right solution.
With our accessories, you can ensure that your separator functions optimally and at the same time meets the specific conditions on site.
