What is sludge dewatering? Sludge dewatering is the process by which water is removed from solids. Typically local regulations dictate the requirement for the transportation and land application of sludge. Anaerobic digestate is approximately 5 8% dry solids. In order to get the solids into cake form, 20+% is required. What is the sludge
Often a polymer coagulant or flocculant is required to improve the dewatering process. Polymers help the solids bind together. The proper polymer improves the rate of dewatering, increases the rate and percentage of suspension of solids and improves the clarity of the effluent. Selecting the right polymer is
SMART offers a line of gravity separators more commonly known as a Sludge Dewatering Box. Digested sludge is pumped through an in-line static mixer where it is blended with polymer. From there, the sludge/polymer mixture continues into the Sludge Dewatering Box. The same pump is used since mixing occurs on the fly and in-line.

Sludge dewatering is an effective method of volume reduction in such cases. It is also an essential pre-treatment method, where incineration is required. Dewatering processes in common use such as pressure filters, vacuum filters and centrifuges require for their design some measure of the sludge dewatering characteristics.
To find sludge loading rate (lbs/hour dry solids): gpm sludge x (% sludge/100) x 8.34 x 60 = lbs/hour dry solids To find polymer usage (l bs poly/ton dry solids): 2000 x gpm poly x 8.34 x 60 x (poly conc. %/100) = lbs /ton lbs/hour dry solids

The ROTARY PRESS is at the heart of the dewatering process, completed by sludge and polymer feed systems. The principle of operation is simple. Sludge is fed at low pressure into the channel and rotates between two parallel revolving stainless steel chrome plated filtering elements.
Sludge is introduced at a central feed well and the supernatant overflows a peripheral weir. The sludge is thickened by the action of a specially designed rake which also moves the thickened sludge to a central hopper, of included angle 60°, for intermittent discharge under hydrostatic head (Albertson, 1992).
