The Coat Factory
The Coat Factory b.v. from Heesbeen gives color and protection to many types of steel and non-ferrous materials. This process creates waste water and sludge. For years, Limburg Filter has supplied the filter cloths for the filter press for sludge dewatering. At a certain point, our customer notices that the sludge processing takes longer and longer. The filter cakes also appear to be much less dry than in the past.
The customer wonders whether there is something wrong with the quality of the last delivered filter cloths. During an inspection of the wastewater treatment plant, we find that the purified water in the sludge settling tank is not clear. It subsequently appears that the lime milk dosage does not work properly. A shortage of lime milk leads to cloudy water. The particles that make the water cloudy clog the filter cloths during sludge dewatering.
The lime dosage has now been adjusted and the purified water is clear again. The filter cloths have also been cleaned in acid to dissolve the blockage. The filter cloths now dewater as good as before.
