  • Thickening Water Treatment and Purification Lenntech

    Sludge treament A volume reduction of approximately 30 80 % can be reached with sludge thickening before a further treatment. At smaller wastewater treatment plants, where the sludge is driven off regularly, thickening usually takes place directly in the sludge storage tank.

  • Wastewater treatment Sludge treatment and disposal

    Treatment methods. Treatment of sewage sludge may include a combination of thickening, digestion, and dewatering processes. Thickening. Thickening is usually the first step in sludge treatment because it is impractical to handle thin sludge, a slurry of solids suspended in water. Thickening is usually accomplished in a tank called a gravity thickener.

  • Sludge Thickening The Water Treatment Plants

    Sludge thickening is a a low investment process used commonly in wastewater treatment plants to remove as much water as possible from the liquid sludge. The method involves increasing the concentration of the solids in the sludge so that they can be easily dewatered.

    Sludge Thickening vs. Dewatering Both are methods of solids concentration and volume reduction. Only the degree of volume reduction is different. Generally thickeners concentrate sludge at lower than 15% concentration, the dewatering units concentrate the sludge to higher than 15% concentration [3].

  • Sludge Thickening Concentration Wastewater Treatment

    The thickening operation separates water from the sludge as much as possible and is cost effective because the cost involved in the process is well offset by the savings gained through the reduction of sludge volume, which decreases the capital and operating costs of subsequent sludge processing steps.

  • Sludge Thickening Degremont174;

    Thickening is the first, and frequently inevitable, step in reducing the volume of sludge extracted from the water line. In fact, it is used to optimise the subsequent conditioning, stabilisation and dewatering stages by reducing structure sizes and operating costs.
