How to judge whether the filter press cloth needs to be replaced? As a filter cloth solution provider for chemical, mineral processing, non-ferrous metal and other industries, BOLIAN combines many years of experience to summarize the following key criteria:
The turbidity of the filtrate increases, and the solid particles penetrate the filter cloth, indicating that the pores of the filter press cloth are worn out or clogged seriously.
The filtration cycle is significantly lengthened, and the capacity is reduced under the same working conditions. This may be caused by the deterioration of the filter cloth's air permeability.
Breaking or tearing: such as holes, cracks or broken stitching.
Thinning or hardening: the material can be attributed to long-term pressure, chemical corrosion or high temperature, which can lead to fibre ageing, loss of elasticity and increased breakage.
Following high-pressure water jet cleaning, acid washing or ultrasonic cleaning, the filter cloth may still be clogged and may have poor water permeability.
According to industry experience, the performance of filter cloth may decline after 3-6 months of continuous use, which should be judged in combination with historical data.
Regular inspection: Record the length of use of the filter cloth, the frequency of cleaning and any changes in filtration effect. You should also establish an early warning mechanism for replacement.
Customized selection: For corrosive materials or high-temperature working conditions, please select acid and alkali resistant and stretch-resistant materials.
Should the above problems occur, the filter cloth should be replaced immediately to avoid compromising production efficiency and cake quality.BOLIAN is willing to provide tailored filter cloth services to ensure the efficient and stable operation of your filtration system.
