Those polyester fabric press filter belts are built to withstand severe conditions like humidity and tension. The woven fabric press filter belt is also known as the filter cloth within the belt filter press. The filter belt within this machine is one of the key parts of the belt filter press as it determines the actual output and thus the overall quality of the dewatering machine.
This filtration process is all about draining by pressing sludge between wire cloth belts in order to dewater the sludge for further processing.
The effectiveness of the belt filter press can be increased by adjusting the pressure on the fabric belt, this filter cloth is able to handle these kind of pressure differences across the total belt. In other words, these belts need to be from top quality and need to be maintained regular to ensure a continuous and effective draining process.
Also adding a flocculent or filter aid during the draining process can help maintaining the filter cloth as the open spaces in the wire mesh are more likely to stay open instead of getting blocked. Thus it will also support the output of dry solids as the drainage flow keeps on working in a continuous way. The woven fabric belt can be cleaned during the operation by means of sprayers which spray water under high pressure at the returning position of the belt, this is to avoid blinding of the wire mesh belt.
