Cleaning is important
In order for you to obtain the best effect from your filtration process, all parameters must be adjusted perfectly.
A filter bag that is not cleaned properly causes an increase in pressure drop, and thus increased energy costs.
However, cleaning a bag too often and at too great a pressure will physically wear the bag out more rapidly and bag replacement will be required more frequently.
Below, you can see what an optimal cleaning looks like.
The video is recorded with high speed camera in order to capture the cleaning period accurately. The actual video clip with the bag has a duration of 0.75 sec. at normal speed, and the impulse seen at the beginning of the clip takes about 0.05 sec. The bag is 6 metres long and has a diameter of 130 mm. The cleaning pressure is 5 bar.
