Model 304B/304M/319 -CST Sludge Capillary Suction Time Tester

CST (Capillary Suction Time) is the performance of the test and the state of the sludge filtering a fast and reliable method, which in 1970 has been widely used in foreign countries. Sludge filtration affect virtually all different types of dewatering equipment output, these devices include: drying beds, belt press, vacuum filter, centrifuge filter, and the like. Standard filter by capillary suction pressure generated from a sludge `absorbent` water, water infiltration rate of change in filter sludge states and depend on the filter cake formed on the filtration paper, CST from the hopper of the two standard electrodes spaced request. Obtained through from the beginning to the time between the two electrodes is CST. Water in the funnel by capillary forces generated by the hydrostatic pressure is much larger than the apex, so the test is not dependent on the amount of sludge. As long as there is sludge can produce CST.
