Separator system:


Just a single drop of petrol is enough to pollute 1 m³ of water. And today every responsible person knows just how precious our water resources are. Pure, clean water is one of the most important fundamentals of life, yet it is exposed to multiple hazards. One of the greatest dangers is pollution from light mineral liquids. These include oils, petrols and lubricants, i.e. petroleum products. These have become indispensable in our world of high technology. But inevitably as a result they come into contact with water and are mixed. To prevent environmental damage caused by the uncontrolled discharge of oil-containing wastewater, effective and safe methods of separation technology must be used everywhere where light liquids come into contact with water.

    The separator technology is based on a simple principle:

    As the wastewater is slowed down at the inlet of the separator, a natural separation process is initiated resulting from the physical features of the different substances. Oils and fats, also known as light liquids, are of a lower density than water and thus rise to the water surface, where they combine to form a layer. The solids, however, are heavier and collect at the bottom of the tank. This behaviour can be observed with solids in any body of water as well as with oils, for example, whenever you add oil to water when cooking. This is already the first step to clear water, which is supported and optimized by KLARO technology in the further separation process to achieve an even higher clarification performance.

    Description of system - Coalescence unit

    The KLARO separator KLsepa.compact+ is a coalescence separator. This means that they are extended by a coalescence unit, which allows a significantly higher degree of separation. While the target limit of the separation efficiency of a petrol separator is less than 100 mg of residual oil per litre of water, with the help of a coalescence unit this value can be reduced to a residual oil level below 5 mg/l.

    The coalescence process

    1. Step:

    In addition to readily separable oil drops in a light fluid separator, very small oil droplets arise, whose density difference to water is too small to make them rise to the surface in the time available. Therefore, they remain in the effluent water.

    2. Step:

    In order to precipitate out these smaller oil droplets, a material is positioned before the discharge, which the droplets adhere to and together form an oil film.

    3. Step:

    Through the flow of further oil, the thickness of the oil filmincreases, until the adhesion of the oil film is exceeded. Individualdroplets work free, whose size is sufficient to riseto the surface, due to the difference in density, and thereforethey are also deposited.
