Depending on the plant capacity, filtration can be achieved within an open or pressure filter.
Optimum performance of the filtration process is ensured through regular backwashing with filtered water and air scour, evenly distributed through our proprietary nozzle underdrain.

Each filter is backwashed independently, hence the guarantee of continuous supply

Depending on the quality of water to be treated and the filtering objectives, different filtering media can be employed : sand, activated carbon, anthracite, pumice, shale, limestone, etc...

• Physical function : retention of suspended particles (suspended solids, iron and manganese precipitate.)
• Physical-chemical : adsorption of micro pollutants (pesticides, detergents, chlorinated solvents, sapid components, etc.) Manganese removal with manganese dioxide.
• Biological function : biodegradation of organic carbon Oxidation of ammonia, iron, manganese , Denitrification.
• Chemical function : acidity correction with calcium.

Filtraflo filters differ by their technological characteristics that adapt to specific water treatment demands and to the type of water to be treated, and facilitate integration into the overall water production line.
