APPLICATION > A pressure filter is designed to treat rawwater from a boring or a well so that the qua- lity complies with the standards of drinking water. The plant is dimensioned according tothe actual raw water type. WORKING PRINCIPLE > The working principle of a Eurowater pressu-re filter is based on aeration and filtration. When the raw water is aerated iron, mangan- ese and mechanical impurities precipitate assmall particles of a filterable size. Thissuspended matter is removed by filtration in the pressure filter. At regular intervals depen- dent on raw water impurity and water consumption...

APPLICATION MAINTENANCE OF THE PLANT PRESSURE FILTER > A manual pressure filter is highly suitable forsmall and medium drinking water supplies where a certain maintenance of the plant is acceptable. Especially suitable for houses and farms situated outside the range of the public water supplies. Maintenance is limited to backwash at regular intervals which is effected by a simple regula- tion of the operating valves.
