Thin film separation refers to separation technologies that are capable of removing even a thin oil film from water. This approach eliminates the build up of a dirt or rag layer, common to two phase separation, at the interface between oil and water. The dirt gets removed with the oil.
The Suparator® technology uses a unique principle to remove every trace of oil on the surface, without any water. Unlike any other oil separation technology or device, it functions independent from the amount of oil and the oil layer thickness. It removes the thinnest possible oil film, even sheen, without any water, and at the same time has a higher removal rate than any comparable device.
To achieve this, the Suparator® principle applies a three-step approach. It gathers all the oil, even traces, collects and concentrates the oil in the second step and only than removes it in the third step.
This active removal of all oil, without leaving any floating matter behind, has very significant advantages over alternatives methods and devices. It gives optimal control over all the pollution in the aqueous medium and is capable of removing even emulsified oil by means of induced coalescing.
Using the Suparator® thin-film separation technology has a significant impact on the solids concentration in the aqueous medium. Typically heavier particles will settle to the bottom of a tank or bath, separating it from the fluid, and will be removed as sludge periodically. Finer materials however tend to remain suspended in the fluid, more so because they are associated with the oil which prevents settling or even makes this material float to the surface. Thin-film removal will separate this material with the oil.
