daf in thickening of slurries and sludges

  • sludge treatment reuse and disposalunep.or.jp

    aerobic stabilisation requires less energy when carried out as part of a composting process. for composting of sludge its solids content should be increased to at least 15 % so that it can be handled as a solid. thickening and dewatering see below of primary and secondary sludges are required to achieve the required solids content.inquire now
