Water, sewage and sludge treatment For better water quality Pure, clean water is essential to life. The ever-growing world population and increasing industrialization have resulted in a growing global market for drinking water, industrial water and waste water. In order to ensure that the world has sufficient water now and in the future, it is today more important than ever to protect natural resources. We have a clear solution for the water conditioning and waste water treatment industries: PRAESTOL® flocculating agents. PRAESTOL® – The right agent for the right job PRAESTOL® flocculating agents are used wherever it is important to separate solids from liquids effectively. They help to clean raw water for use as drinking water, treat and condition the circulation water used in industrial processes, and clarify municipal and industrial waste water. They improve de-watering of thickened sludge during static or mechanical de-watering processes. PRAESTOL® is also used in the paper industry, in the sugar industry, in the chemical-technical industry and in the oil and minerals mining industries.
