Since20Century70Since the [year], capillary suction time has been used to characterize the filterability and conditionability of sludge.InspectionMethod.
The filterability of sludge is a performance indicator of dewatering equipment (including: drying beds, belt filter presses, vacuum filters, filter presses, and centrifuges).
7*9cmCapillary suction pressure generated by the filter paper is used to extract sludge from...“Suction”Water. The rate at which water permeates through the filter paper depends on the condition of the sludge and the filterability of the filter cake formed on the filter paper.CSTIt is obtained from two electrodes, with a standard distance between the electrodes and the funnel. The time the water flows between these two electrodes constitutesCST。
304B The electronic equipment has been improved, replacing the mechanical counter with a liquid crystal display. The design and testing of this device comply with electromagnetic compatibility standards in Europe and the United States. The power input can be set according to European or American standards.。
The CST (Capillary Suction Time) test instrument has been widely used internationally since the 1970s. Its test is a quick and reliable method to demonstrate sludge filtration and condition, and is applied in various fields, mainly including:
1) Due to the filterability of sludge affecting the output of almost all types of dewatering equipment, including dewatering beds, belt presses, vacuum filters, filter presses, and centrifuges, the CST measurement results guide the stable operation of the aforementioned equipment.
2) In the processes of urban sludge dewatering and oil field waste drilling fluid flocculation treatment, determine the difficulty and destabilization of sludge dewatering using CST, and identify the type and dosage of the flocculant.
3) During testing of oilfield chemical treatment agents, such as in drilling fluid tests, evaluate the inhibition and dispersibility of mud, the anti-swelling capacity of drilling fluids, and determine the type and amount of treatment agents through CST results.
