    Filtration. Continuous Backwash Filter. The Parkson DynaSand ® Filter is an upflow, deep bed, granular media filter that filters liquid suspensions to the designed effluent quality, while at the same time cleaning the sand bed so the filter does not shut down during the backwash period. Feed water is passed upwards through the sand bed and exits the rapid sand filter as clean water.
