Customized Filter Backwash Roots Blower

Working Principle:

Backwashing is a process that is used in water and wastewater treatment to pump water backward through filter media, which includes anything placed in a filter that changes the quality of water flowing through it. This process sometimes involves the intermittent use of compressed air and is a form of preventative maintenance so filter media can be reused.

Air Assist In Backwashing

Air assist is preferred in backwashing as it provides a more vigorous washing action. Air and water are applied for several minutes as the bed is agitated. The wash water that has risen from the backwashing process is removed. Then, a second lower pressure backwash, without air assist, makes sure bubbles are removed from the filtering media.

Heli blowers provide the air for backwashing in this process. The typical arrangement is one blower per filter. The amount of air required depends on the depth of the water and surface area as well as the depth of the filter media.
