De Boer Machines Nederland B.V. delivers water purification installation for process water. These sedimentation installations separate fine settled, dissolved and floating dusts such as sand, clay, additives and sawdust. The contaminated process water stream is cleaned by means of a water treatment unit; a clearing unit.

In the supply pipe to the clearing unit an automatic poly-dosing unit controls the dosing of coagulant and flocculant. In the clearing unit itself it is possible to place a supplementary cross flow plate with a total surface of 60 m² (approximately as large as the surface of the sediment basin) to residue.

The residue will be pumped out of the unit e.g. to a deposit outside, to be transported afterwards. The treated process water goes through a fall back into the storage pit from which it will be pumped into the production process again.

• Brick making industry
