Our filtration system operates the "co-flow" using a fixed bed of sand and a special anti-clogging water distribution system specially designed by IDROSISTEM energy. It also benefits from our patened backwashing system which completely stops loss of sand during processing.
Traditionally, the filter medium is made from fine granulometries which allow for an effective filtration process but this has the disadvantage of requiring frequent backwashing operations (and consequent filtering interruptions). On the other hand, using a coarse filter medium, backwashings are reduced but the filtration results are not as good. Therefore, to benefit from the advantages of different granulometries, we use a multi-layered filter (with a granulometry range from 0.3 mm to 8 mm).
How does it work?
The main aim of sand filtration is to remove suspended solids, oils and surface agents from the water coming from the air/water separators.
During the filtering stage the filtered substances cause an increase in head loss. When the pre-set value is reached backwashing occurs automatically using filtered water. However, due to the weight of filtered substances, using only water doesn't adequately clean the filter. Our backwashing system uses both water and air.
