Two AquaDisk Cloth Media Filters Replace Six Granular Media Units, Boosting Capacity 540% And Cutting Backwash Volume By 97%

The Portland, Indiana, Wastewater Treatment Plant (WWTP) had been using six granular-media filter units for tertiary treatment since the 1980s. The plant’s treatment protocol includes fine screens for grit removal, followed by primary clarifiers, trickling filters, aeration basins, secondary clarifiers, the tertiary treatment system, and then chlorine disinfection.

WASTEWATER APPLICATION NOTES

  • Applying Oxidation Reduction Potential Sensors In Biological Nutrient Removal Systems Oxidation Reduction Potential (ORP) is commonly a misunderstood science. Applying ORP to wastewater treatment is often a considered a mystery and sometimes called “black magic”. By Bob Dabkowski Hach Wastewater Specialist
  • Dissolved Oxygen Measurement
    Dissolved Oxygen Measurement

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

  • Dissolved Oxygen Measurement In A Wastewater Treatment Plant
    Dissolved Oxygen Measurement In A Wastewater Treatment Plant

    Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the non-settleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy.

    Application Note: Environmental Applications Of The Agilent 1290 Infinity UHPLC: The Evolution Of Chromatography This application note presents examples of the use of UHPLC (ultrahigh performance liquid chromatography) for environmental applications using the new Agilent 1290 Infinity LC. By E. Michael Thurman and Imma Ferrer Center for Environmental Mass Spectrometry Department of Environmental Engineering University of Colorado Boulder, CO, USA
  • Application Bulletin: Reverse Osmosis
    Application Bulletin: Reverse Osmosis Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached
  • Chlorine Measurement In Wastewater And Regulated Discharge Requirements
    Chlorine Measurement In Wastewater And Regulated Discharge Requirements

    Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

    NEOSEP® Membrane Bioreactor System Simplifies 'Fundamental Necessities' Of MBR

    The NEOSEP® MBR system features Kruger’s uniquely designed K-120C and K-240C flat sheet membrane modules.  The modules offer several innovative design features that enhance ease of installation, operation and maintenance.  This includes an integrated central lifting eye, offering an incredibly well balanced module that makes installation and retrieval a simple and stress-free process.

  • Monitoring Aromatic Organics For Optimizing Coagulation

    With the increasing awareness about the negative effects of organics within the water and wastewater treatment process along with increasingly strict water quality regulations, the need for more effective organics removal is becoming more important.

  • Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications
    Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications Total Organic Carbon (TOC) analysis is an effective technique for detecting and measuring the presence of organic contaminants in waters used throughout industrial processes, municipal water uses, and for determining residual concentrations of organic material on the surfaces of equipment used in the manufacture of active pharmaceutical ingredients. By Jeffrey Lane, Steve Skalski, and Gary Engelhart, OI Analytical
  • Bringing Efficiency And New Confidence To BOD5 Analysis Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons. By Bob Dabkowski, Hach Company
