TYPOLOGY FILTERS

WHEN TO USE IT

Water filters are equipment used for the primary waters and sewage filtration for civil and industrial application. They are used when is necessary to obtain an effluent to be reused, therefore particularly clear and with a reduced presence of organic substances. The FSQ type filter employs the quartz sand as filter medium. On request, it is possible to use multi media filtering layers.

HOW IT IS MADE

The filter consists of a vertical cylindrical container complete with bottom drain, support feet, manhole, lifting eyebolts, flanged inlet and outlet piping, nozzles, diffusers, valves, pressure gauges and electro-pneumatic panel.

HOW IT WORKS

The filtration is carried out according to a discontinuous cyclic process: a differential pressure gauge stops the flow of water to be filtered as soon as the pressure difference reaches a pre-set threshold level; at the same instant, the filter back washing cycle is automatically activated, with air and water being introduced from below. The standard execution provides for a base plate as support for the filter bed, on which the nozzles for back washingare seated. The high filter reliability is ensured by the automatic backwashing system and by the short time required to restore the filter medium.
