Design of a Filtration System for a Small Scale Water

Filter sand has a grain size of 0 4-1 0mm which is large in comparison with many of the smaller particles carried by water and the rapid gravity sand filter can only operate as intended when coagulants have been used Interception of the suspended matter by the sand is a fairly complex process but most of theGet price


Sand Filter

The pressure filter is operated at elevated pressures thus prolonging the filter cycle and/or increasing the rate of flow of water through the filter Gravity filters are commonly operated at 2 GPM/sq ft * whereas pressure filters are operated at 3 GPM/sq ft and higher The rapid sand filter is operated with clarification ahead of the filter Get price


Gravity Sand Filter

Since the HEI gravity flow sand filter continuously cleans a small portion of the media bed the dirty backwash water comprising approximately 5% of the total flow may be continuously returned to the primary clarification device without stopping or surging the system Get price
