CMDF Filter Pad
Prior to the first filtration it is recommended where possible to pre-rinse the closed filter with approximately 50 litres of water per m2 at 1.25 times the flow rate. During pre-rinsing check for leakage, re-tighten to eliminate if necessary.
Carlson range of XE filter sheets may be sterilised with saturated steam or hot water. The pressed filter pack has to be
loosened slightly to ensure that the steam has entirely sterilised the system. Final pressure should only be applied to the filter pack
the entire filter has cooled down.
Sterilisation with steam:
Steam quality: Steam has to be free of foreign particles and impurities
Temperature: max 1340 c (saturated steam)
Sterilisation with hot water:
Water quality: The water should be softened and be free of impurities
Temperature: 80-850 c
Duration: 20 minutes
The Carlson range of XE filter sheets can be forward and back washed using softened water to extend the life and reduce the costs of filtration. This is, however, very much dependent upon the application and filtration conditions.
Cold rinsing: in direction of filtration for approximately 5-10 minutes
Temperature 15-200 c
Hot rinsing; forward or reverse direction of filtration for approximately 10 minutes
Temperature 60-800 c
