Sludge Capillary Water Absorption Time Tester

The CST Capillary Suction Time Tester has been widely adopted internationally since 1970. It serves multiple applications: In municipal sludge dewatering pretreatment, CST measurements assess sludge dewatering difficulty to determine polyacrylamide (PAM) selection and optimal dosage, enabling PAM optimization. Since sludge filterability and condition influence the output of nearly all dewatering equipment types—including drying beds, belt presses, vacuum filters, filter presses, and centrifuges—rapid and reliable CST measurements provide valuable operational guidance for these devices; In oilfield chemical treatment agent testing and research, it evaluates mud dispersant suppression capability, drilling fluid swelling resistance, drilling fluid hydration suppression capability, and optimizes wellbore fluid formulations—such as treatment agent types, dosages, and ratios. It also serves as a novel method for analyzing and classifying shale types. During waste drilling fluid flocculation treatment, CST values provide a direct indication of destabilization, thereby determining the flocculation performance of flocculants to identify optimal flocculants and their concentrations.
