Regeneration/Backwashin

If the filtration process allows regeneration of the filter matrix, the filter sheets can be forward and back washed with softened water without bio burden to increase the total filtration capacity and thus optimizing economic efficiency.

Regeneration is carried out as follows:

Cold rinsing 
in the direction of filtration
Duration approximately 5 minutes
Temperature: 59 – 68 °F (15 – 20 °C)

Hot rinsing
forward or reverse direction of filtration
Duration: approximately 10 minutes
Temperature: 140 – 176 °F (60 – 80 °C)
Rinsing flow rate should be 1½ of the filtration flow rate with counter pressure of 0.5-1 bar

Please contact Great Wall for recommendations on your specific filtration process as results may vary by product, pre-filtration and filtration conditions.
