  • 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 ...

  • Biomass properties and permeability in an immersed hollow fibre membrane bioreactor at high sludge concentrations

    This study aimed to investigate the influence of biomass properties and high mixed liquor suspended solids (MLSS) concentrations on membrane permeability in a pilot-scale hollow fibre membrane bioreactor treating domestic wastewater. Auxiliary molasses solution was added to maintain system operation at constant food-to-microorganisms ratio (F/M = 0.13). Various physicochemical and ...

  • 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 ...

  • Lagoon and Ditch Sediment Dewatering Utilizing Geotube Preliminary Pilot Demonstration - Case Study

    Project Background Geotubes have proven to be a practical and economical way of dewatering a number of domestic and industrial sludges, and sediments, such as river and lake sediments and contaminates, wastewater lagoon sludge, water treatment plant sludge, packinghouse sludges and wood products sludges. The Michigan Department of Environmental Quality (MDEQ) is interested in evaluating ...

  • 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 ...

  • Strategic Abatement of Emission to Economically Support Development of High Profile Real Estate Adjacent to a Wastewater Reclamation Facility

    ABSTRACTThe Des Moines Wastewater Reclamation Authority operates a 97-million gallon per day regional wastewater reclamation facility (WRF) largely constructed in the mid 1980s to serve the greater Des Moines, Iowa metropolitan area. Originally constructed in a largely rural area, current plans for the area around the WRF establish a need for emissions control to reduce offsite odor impacts, in ...

  • Maximum Efficiency for...Saving Water

    In an attempt to protect our ecological surroundings and minimize the negative effects of industrial processes, it is necessary to purify and recover the waters used during washing operations of sand washing, quarrying and recycling operations. The first step is to recover 100% of the waters used and to eliminate the concentration of sludge, thus Baioni's solutions aim at offering a full sludge ...

  • New treatment plant to feature ceramic membranes

    The Parker Water and Sanitation District (PWSD) in Colorado has contracted for a membrane treatment system for its Rueter-Hess water treatment plant project. The new plant will treat water from the Rueter-Hess Reservoir (RHR), which is being built three miles southwest of downtown Parker on Newlin Gulch, which is a tributary drainage of Cherry Creek. The reservoir and associated treatment plan ...
