  • Liquid Level/Interface Monitoring in Flocculant/Sludge Control (.pdf)
    In municipal and industrial wastewater treatment plants, sludge clarifiers are utilized to separate solids from the water treatment effluent system by introducing air and flocculants. This process results in the sludge rising to the top of the pond or tank and spilling over a weir into a separate
  • Field Comparison Testing of Septic Tank Designs
    designed for quiet, laminar fluid-flow and minimum 'dead space' such as in longer, narrower tanks. A correlation is suggested between formation of unwanted heavy scum and the presence of tank airspace where vegetative molds live and trap rising sludge particles. The presence of partitions with small
  • Nitrogen Needs Assessed More Accurately
    of the western United States, " says Vigil. Vigil is now working on ways to help soil-testing labs give more accurate assessments of how much cattle and swine manure, plowed-under green crops like rye and alfalfa, or sewage sludge help meet crop fertilizer requirements and reduce the need for commercial
  • Which Pump Is Right for Me? Pushing Through a Host of Factors to Select the Right Pump
    bypass, pumping polluted wastewater, and pumping settled sludge. A 6 inch trailer mounted jet pump on a construction site. The High Pressure Jet Pump: (The 4th red pump from top) is designed to be used as a fire pump, to jet casings or wellpoints without drilling/digging, to pressure agricultural
  • Fluid Analysis - A Preventive Maintenance Tool
     empirical techniques, to record viscosity, consistency, water contamination, metal contamination, and possible acidity, particle formation, and presence of sludge. These objective observations can tell us much about the fluid. Often, suspicions of contamination arise during this step, and can be confirmed
  • Microbial growth in fuel
    the additives are degraded and consequently their effect is lost. Microbially Induced Corrosion: Hydrogen sulphide is produced by sulphate reducing bacteria. This enters solution and is highly corrosive, causing severe pitting of fuel tanks and pipework. Sludge Formation: Microbial debris
  • Biochemical modeling
    in underground pipelines and conveyed by gravity to the treatment plant. This combined mill effluent is passed through trash screens to remove suspended solids before it is discharged into primary and secondary clarifiers to enable the settling of suspended solids into sludge. The overflow from
  • Reducing Costs at a Drinking Water Plant through Monitoring of Total Organic Carbon (TOC) and Process Optimization
    TOC removal, if. necessary. If a plant relies on a third. party laboratory for its TOC values,. the results will typically arrive too. Caustic. Sludge. Soda. late to actually impact the current. Removal. To Filters. plant process. Figure 1: City of Englewood Pre-Treatment. almost $137,000
