ECOTEAM designs dewatering unit to reduce sludge's moisture content.
Dewatering is a physical unit operation allowing:
Reducing costs for trucking sludge to the ultimate disposal site
Dewatered sludge is generally easier to manage
Dewatering is required before sludge's incineration in order to increase the energy content or reduce the cost
Dewatering is required before composting to reduce the requirements for supplement bulking agents or admendments
Dewatering is required before landfilling to reduce leachate production at the landfill site
Dewatering can render the sludge odorless and non-putrescible
The typical "Sludge chain" in the management of effluent from industrial productions consists in:
Settler
Thickener
Filterpress
Dryer
The units of sedimentation use the difference in specific weight allowing clarification of water and the relative concentration of the turbid muddy water which can undergo further treatments such as thickening which enriches the concentration.
