Factory Acceptance Checks for a Belt Filter Press
Buyers should define measurable pass or fail checks for gravity drainage, wedge formation, roller pressing and continuous belt washing before signing off a belt filter press at the factory.
Before accepting a belt filter press, decide how the factory acceptance test will prove that each dewatering stage works: gravity drainage, wedge formation and roller pressing, plus the continuous wash system. Ask the supplier to propose checks you can witness and record, and agree the pass or fail limits in the purchase order rather than at the test.
For gravity drainage, will the test use a sludge sample comparable to your own, and how will the supplier show that free water separates before the wedge? For wedge formation, can you observe that the sludge is contained and progressively compressed without spillage at the edges? For roller pressing, what measurable output will be recorded, and against what agreed reference? For the continuous wash system, confirm that belts are cleaned across their working width during running.
Make each check repeatable: state the sludge sample, run duration, observation points and who records results. A demonstration that only shows motion is not a pass or fail check.
Before requesting a quote, confirm with the supplier which acceptance checks they will support, what test sludge they will use, how results will be documented, and whether any catalog specifications are reference values only rather than guarantees for the supplied model.
