Dynasand operation manual

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. At the same time, sand can be . DynaSand unit is a continuously operating sand filter. Availability in maximized by elimination the need to take the unit out of service for backwashing. The sand is cleaned at all times by means of an internal washing system. Operation is straightforward and reliable. DynaSand improves the process: ♦ No first filtrate. Always clean effluent. DynaSand improves the process • no first filtrate – always clean effluent of a high quality • no shock loads on the wash water treatment system • High suspended solids without need for pre-treat-ment • low head loss • low energy consumption • low supervision and maintenance costs • no interruption of the operation for backwashingFile Size: 1MB.

DynaSand WWR can be used for final polishing in the final step of the purification of waste water. Due to continuous washing the DynaSand filter can purify waste water with high concentrations of particles, so that you get about times higher capacity compared to backwashed sand filters. Washing of the filter media is adapted to load and flow. The range of DynaSand filters is under constant development and includes the latest developments of sand filters, such as material that is extremely resistant to the abrasions caused by sand that is in constant motion during normal operation. The advanced materials mean less maintenance and prolong equipment life.

DynaSand™ is a world-leading continuous sand filter developed by the Axel Johnson Institute in Sweden in the late s. DynaSand is used to clean and produce water for drinking, industrial processes, waste water recycling and waste water treatment before the water is discharged into a recipient. The DynaSand ® EcoWash ® Filter expands upon the DynaSand platform by allowing continuous filtration with intermittent sand washing. Operating in this mode, the system reduces the amount of reject water, increases filter performance, maximizes the airlift life cycle, and reduces maintenance time.
