Description

The Parkson DynaSand® EcoWash® Filter is a unique system that filters liquid suspensions to the designed effluent quality, while at the same time cleaning the sand bed so the filter is not shut down during the backwash time. Feed water is passed upwards through the sand bed and exits the top of the filter as clean water. At the same time, sand can be removed from the bottom, cleaned and returned to the top. A small portion of the filtered water is used to wash the sand and leaves the filter as a reject stream.

The DynaSand® EcoWash® Filter allows continuous filtration with intermittent sand washing. Operating in this mode, the system reduces the amount of reject water, increases filter performance, maximizes the airlift lifecycle, and reduces maintenance time.

The DynaSand EcoWash Filter is available as either a standalone package unit or a modular concrete design. The package units are constructed of either 304 SST or FRP. Internal components of both package and concrete units are built with Stainless Steel (SS) and/or FRP. Filters are available in 40” standard bed or 80” deep-bed design depending on the nature of the application.
