The
trapping properties of a filter cloth or filter fabric make it useful for a
variety of industrial applications. Some of the common processes for which it
is used include water purification, food processing, and sludge removal from
liquid products.
If
you have been using filter cloth in Qatar,
you may also be aware of the common issues that affect its usage. Due to
frequent use, the cloth gets filled with small particles that it is supposed to
free the liquids from. With time, these start to penetrate the cloth and get
lodged in the depth of its weave. This reduces the property of filterability.
The particles therefore have to be removed periodically to maintain proper
filtration rates.
A
good and simple strategy to clean filter cloths is to do the cleaning when the
cloths are still set up on the filter press plates. There is a certain
mechanism to do this and the special units needed for the action are holding
tank, pumps, re-circulating pipes and valves. Your filter press supplier can
provide you these things. Do take care to ensure that the cleaning solution
does not spout from between the filter plates as you begin to clean up the
cloth. This is important in lieu of the fact that these cleansing liquids
contain components like hydrochloric acid mixed with non-ionic detergent at
ambient temperature. Caustic solutions may also be used as per the kind of
contaminant being removed from the cloth. Polypropylene fabrics can be cleaned
in various solutions as their fibre is highly tolerant to acids and alkalis.
