The type and the added quantity of the polymer should first be determined by experiment.If two kinds of polymer are required,we recommend the dehydrator with two flocculation tanks.The stirring device in the sludge tank runs continuously to ensure the relatively stable concentration of inlet sludge.
Polymer solution needs to be ready using polymer preparation device before screw press starts running. Polymer solution and sludge are mixed and stirred,forming flocs in the flocculation tank,As the sludge makes its way down to the drum by the rotation of the screw,thickening and dewatering takes place. Filtrate comes out from the gap and sludge cake is discharged from another end.Fitrate can be reused by further treatment. Sludge cake can be transferred by conveyor.
Simple process,efficient and energy saving dewatering, low system investment system can be programmed to make the operation more convenient and accurate Unique flocculating agent to make sludge dewatering easier Uniform and accurate dispensing, saving running cost.
