cleans the filter to preserve water quality and also extends the life of the filter; however, backwashing
too frequently can lead to degraded filter performance.
Anti-Clogging Water Distribution: The quality of filtration depends mostly on a good distribution of inlet water, the water and air backwashing
and an homogeneous drainage in each point of filtering volume.
A new screen filter replaces the previous sand bed, thereby reducing the backwashing
cleaning cycle from 90 sec to 12 sec.
can be chemically enhanced to remove dissolved organics and bacteria through the use of alkalised agents, or a chlorine based disinfecting agent.
Replace your aging sand or DE filtering system with a cartridge filter that does not require backwashing
and saves water.
As a result, the petroleum industry is cleaning up its act and profiting in numerous areas with self-cleaning filtration systems: from automated refinery catalyst bed protection systems that can save millions in lost production and wasted catalyst; to backwashing
filters that minimize plugged-well risk and maximize platform productivity; to filters that enable slurry oil reuse at refineries for the first time; to those that eliminate operator exposure to dangerous amines.
When the filter vessel reaches its cleaning capacity, which is detected by a pressure switch, a backwashing
cycle starts and clean filtered water is supplied to the machine's dielectric tank.
The mill also decided against using dissolved air flotation (DAF) clarifiers or backwashing
pressure filters equipped with metallic filter elements.
