Backwash cartridge filter BWFA Model

Engineering

Backwash cartridge filter BWFA Model

Compatible with super fine particle sludge for carbon, carbide etc
Model BWFA-7 Total dimension 1300W x 880L x 1900Hmm

Features

Enhanced filtration efficiency
High precise filtration (partcle size up to about 1μm) is performed using new developed slit type filter. Running cost will be reduced due to non-use of fileration aid.

 

Less-consumables
As Consumabeles is not generated less than like a conventional disposable cartridge filter, Running cost will be reduced.

 

Enhanced backwashing
Backwashing is effectively achieved due to original system and the clog of filter is restrained.

 

Easy recovery of sludge
Concentrated sludge is recovered easily to outside system. Easy maintainance due to symple structure.

Application

  • Super fine processing for honing, lapping, and super finish grinding.
  • Super fine particle sludge for carbon, carbide etc.

*1:Max flow rate is the flow in pure water. The condition of treated liquid such as SS concentration, viscosity, and temperature varies the flow rate.

*2:Nominal filtration rating means the filtration ability of element that capture many particles (over 50 %) above shown. This value is a performance test result done at our facility.

*3:The ability above might not be performed, when a little water is mixed to oily coolant.
