Description:

The CBS continuous backwash sand filter is an up-flow, moving bed filter that is constructed with various media depths for different applications and configurations. Raw water enters near the bottom of the tank by means of a stainless steel water distributor, Suspended solids are filtered out as the raw water flows up through the media bed. As the filtrate reaches the top of the filter, it passes over the effluent weir and is discharged. A portion of the filtrate is diverted through the san washer and used for cleaning and transferring the waste solids.

The CBS continuous backwash sand filter employs a backwash rinse that is performed continually while the tank is processing water. An air lift pump, located at the center of the module draws the media from the bottom of the filter up into the wash box. As the media is released into the wash box, it falls into the sand scrubber where the filtered solids are separated from the sand.

From there, the filtrate carries the solids out as waste (backwash). The washed sand falls down onto the media bed for continued use.

Applications:

• Chemical phosphorus removal
• Pretreatment to other processes

Industrial

• Metal finishing
• Backwash recovery

• Cooling tower blowdown
• Steel mill scale
• Chemical processing
• Ideal for pretreatment in lieu of gravity filters
