Sludge thickening methods
WebbCommonly used sludge treatment methods are: thickening, digestion, dewatering, drying, incineration, solidification and integrated use. There is also the more final disposal method of sanitary landfill in landfills. What is the dewatering process? WebbSludge Thickening Methods. In primary or secondary treatment of wastewater, mechanical sludge thickening of sludge from clarifiers has become the industry norm prior to digestion or dewatering. Alfa Laval’s sludge thickening machines all have enclosed designs plus very low maintenance and odour control requirements:
