Standard sludge testing mixing/timer

This sludge testing mixing timer is recommended by the Water Research Centre to evaluate the stability of sludge.
Often used in conjunction with a sludge capillary water absorption time measuring instrument (CST). At a certain stirring speed, the sludge is stirred, which simulates a certain shear force. In this way, the physical strength of the treated flocs can be evaluated, and the sludge stability of different dewatering machines can be obtained.
·The upper motor can continuously stir the sludge
·Detachable mixing blades are flexible and easy to clean.
·The stirring time can be adjusted from 1 to 99 seconds, with an interval of 1 second.
·A time setting button can be used to set the standard time between 10 to 30 seconds and 60 seconds.
