  • Ceramic Membranes in Sludge Thickening Applications

    The Aerobic Digestion group has recently been conducting pilot testing of silicon carbide ceramic membranes manufactured by the Danish company Cembrane A/S.  This promising technology shows a great ability to filter water even in the challenging high solids environment of sludge thickening.  The results of the pilot testing have led the aerobic digestion group to utilize ...

  • Mine backfill

    Mine backfill is defined as the material used to fill the cavities (i.e., stopes) created by underground mining. Backfilling can be a means to dispose of sludge and/ or tailings which may contain hazardous materials and to reduce surface environmental impacts by storing tailings underground. Alternately, backfilling with nonhazardous materials can allow for mining productivity improvements. To ...

  • Paste thickener bed level measurement

    Numerous studies and papers have been devoted to the subject of thickener design and operation to achieve specified throughput and discharge densities. Mathematical models have been developed that present methods for sizing thickeners and predicting performance under varying process conditions. The compression effect of deeper beds on dewatering performance is a recognized phenomenon. This is one ...

  • Application of forward osmosis (FO) under ultrasonication on sludge thickening of waste activated sludge

    Forward osmosis (FO) is an emerging process for dewatering solid–liquid stream which has the potential to be innovative and sustainable. However, the applications have still been hindered by low water flux and membrane fouling when activated sludge is used as the feed solution due to bound water from microbial cells. Hence, a novel strategy was designed to increase sludge thickening and reduce ...

  • 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 ...

  • Latest CDE plant installed in Trinidad

    In November 2006 a CDE Sand Washing Plant was installed with the Sampete Group based in Wallerfield Armia, Trinidad. Before this installation the raw material had been stockpiled as waste, compromising the efficiency of several limestone quarries in the east. It provided a considerable challenge for traditional systems as it is overburden mixed with clay-bound material which is extremely plastic ...
