  • A case study of the sludge thickener - Large Commercial Facility (Office Building)

    Costs for industrial waste reduced with sludge thickener Some office buildings and large commercial facilities have wastewater treatment facilities underground. In such case, it is difficult to take dewatered cake out, so sludge is kept in liquid form and vacuumed out by pump without being dewatered. This potential customer also had been vacuuming out the liquid sludge, and had considered how to ...

  • Environmental sludge treatment

    During the process of wastewater treatment, sludge generation is an important and at times crucial issue to be addressed as inadequate sludge handling system can pose serious environmental implications. Liquid sludge can be easily thickened and reduced to a solid cake via sludge thickening / dewatering. This reduces the volume of liquid sludge significantly, usually resulting in a quite ...

  • Accelerated anaerobic release of K, Mg and P from surplus activated sludge for element recovery and struvite formation inhibition

    Accelerated release of potassium (K), magnesium (Mg) and phosphorus (P) from surplus activated sludge (SAS) was investigated to develop a new system for the recovery of the elements. Anaerobic cultivation of SAS during 24 h released 78% of K and about 50% of Mg and P from SAS more effectively compared to aerobic cultivation (K: 40%, Mg: 15%, P: 15%). Furthermore, the addition of sodium acetate ...

  • Sedimentation Processes

    Sedimentation is the process of allowing particles in suspension in water to settle out of the suspension under the effect of gravity. The particles that settle out from the suspension become sediment, and in water treatment is known as sludge. When a thick layer of sediment continues to settle, this is known as consolidation. When consolidation of sediment, or sludge, is assisted by mechanical ...

  • The Effect of the Microsludgetm Treatment Process on Anaerobic Digestion Performance

    ABSTRACT Thickened waste activated sludge (TWAS) from biological treatment processes is less amenable to anaerobic digestion than primary sludge. This is due to TWAS being composed mostly of cellular material and extracellular polymeric substances (EPS) instead of more easily digestible carbohydrates and fats that are typically found in primary sludge. In an attempt to improve TWAS digestion ...
