1. Turbidity of raw water
High turbidity of raw water will bring too many impurities to the activated carbon filter layer, which will be retained in the activated carbon filter layer and block the surface of the activated carbon, preventing its adsorption effect from playing. In the long run, the impurities will stay in the activated carbon layer and form a mud film that cannot be washed off, causing the activated carbon to age and fail.
2. Backwashing cycle
The length of the backwashing cycle is the main factor that affects the filtration effect. If the backwashing cycle is too short, the backwashing water will be wasted; if the backwashing cycle is too long, the adsorption effect of activated carbon will be affected.
3. Backwashing strength
In the backwashing of the activated carbon filter, the expansion rate of the filter layer has a great influence on whether the filter layer is thoroughly flushed. If the expansion rate of the filter layer is too small, the lower layer of activated carbon will not be suspended and its surface will not be washed cleanly; if the expansion rate is too large, the carbon will easily run away.
