Sludge thickening and dewatering is two important stages in treating sludge. Thickening is the first step of sludge treatment in which the solids concentration is increased and the total sludge volume is correspondingly decreased, Thickening commonly produces sludge solids concentrations between 15% and 20%. Then, dewatring process reduces the most moisture content of the sludge.
LZZG use filter press(mechanical dewatering) for dewatering. Separate liquids and solids utilizes the principle of pressure drive, after the mechanical dewatering process, the sludge will results in a 95% reduction in volume, which will be convenient for storage and transportation. Most overflows will be recycled or reusing.
Sludge treatment system is imporatant in treating solid waste. It minimizes the water waste, enabling the re-treatment of sludges so that they can be easily stock or landfill. LZZG sludge treatment system usually used after sand washing machine, dewatering screen, tailing dewatering screen or sand recycling machines, widely applied for sandstone aggregate plant, precious metal dressing plant, ceramics, glass and other industries.
