The water used for drinking, washing or technological use, whether flowing from water mains or private supplies, generally contains impurities such as sand, clay, silt and so on.

In order to protect the water supply systems (valves, pressure switches, taps, boilers), it is necessary to carry out a filtering at the entry of the water system to remove such impurities.

If water only contains low concentrations of sand or solid particles, cartridge mechanical filters are used. If water turbidity is due to clay, silt, and/or colloidal substances, filtering is to be carried out by using quartz sand multi-layered filters of different grain sizes and catalysing masses which are able to retain high amounts of such impurities, like the Desabb Industrial filters.

In some cases (high turbidity, presence of particular colloidal substances, small solid particles) it is neccessary to install an automatic metering system to add a flocculating agent enabling to retain the above mentioned substances and to reach a very high filtering grade, thus reducing the bacterial charge too.

If water contains iron, manganese and other foreign substances besides clay and silt, please contact Meta Engineering Ltd. Sales Department.

Desabb Industrial clarifiers are manufactured in metallic carpentry. Backwashing is automatically carried out. The distribution system is made up of a plate with diffusers. The valves are pneumatic buttery valves and the system is controlled by GEL Electronic Filtering Timer.
