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.

Continuous Operation. Continuous mode can be achieved by moving the selector switch to the "Manual" position. In continuous mode the backwash valve will be open and the drive motor will be running resulting in continuous backwash. This mode of operation may be necessary if the installation experiences high solid loadings.

from the sand, so backwash water can remove the particles more easily. This air wash generally is turned on before the backwash cycle. If both are used at the same time, some sand may be washed away. The compressed air rate can be two-to-five cubic feet per minute per square foot (cfm/ft2) of filter surface, depending on the filter.

Equipment characteristics. It has high efficiency and works continuously for 24 hours without shut-down and backwashing. No backwash valves and standby filters are required. The operation cost is low, and no backwash pump with high lift and large flow rate is needed to reduce operation cost. The maintenance cost is low.
