We always begin by establishing which kind and type of contaminants must be removed. This is necessary in order to arrive at the best solution. For this reason we have our own laboratory where we can do research on the contaminants, the carrier medium or the filters used. The following are some of the studies carried out:

1. Research on filter elements used
2. Determining particle size
3. Determining the sort of particle
4. Finding out process information, for example viscosity and acidity
5. Behaviour of contaminants in the carrier medium
