  • 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

The Captivator™ System

The Captivator™ System

The Captivator System improves a conventional process by replacing primary clarification and separate sludge thickening with a VLR® Contact Tank and a Folded Flow® DAF applied to the liquid stream.  Organic matter is extracted from raw wastewater and sent directly to anaerobic digestion.  Since less BOD is sent to the biological aeration tanks, less energy is required by the process.  Waste activated sludge is circulated to the aerated VLR contact tank at the front end of the plant.  The Captivator System reduces capital investments otherwise required for primary clarification, separate sludge thickening, and normal aeration tank volume.

    New Drinking Water Regulations Sought For Algal Toxins

    Excess nutrients, blue-green algae (cyanobacteria), and cyanotoxins have long been a problem for wastewater treatment plants — many states regulate nutrient levels in discharged water — but now drinking water plants are being eyed for regulation as well.

    WWEMA Window: Bridging The Optimization Gap

    The term “optimization” is becoming increasingly ubiquitous in our industry. Search almost any conference program, read through a trade journal, or sit in an annual planning meeting and you are likely to see or hear the word. However, as it gains popularity, optimization may be generating more questions than answers. Utilities often ask what optimization means and how to get started. For those that have already made changes, they may be asking if their utility is fully optimized.  By Kurt Tyler, Hach Company

  • Increase Revenue With New Commercial Metering Technology
    Increase Revenue With New Commercial Metering Technology

    Revenue for water utilities is circling the drain. Most commercial water meters can stand up to the high water flow of commercial water customers, but these same meters often have a hard time measuring low water flows and retaining accurate meter reads over time and continuous flow conditions. Grocery stores, for example, do not pay for the scant amount of water used for produce misters because it passes through many commercial water meters without detection. These low flows add up to big dollars and are forcing water utilities to take a hard look at the accuracy of their meter fleet.

    Arsenic is one of the most common elements in the earth’s crust and is commonly found in many locations at varying concentrations. The Midwestern United States has locations that are heavily laden with arsenic because of certain geological settings and conditions. This naturally-occurring arsenic can leach into groundwater potentially causing elevated levels of arsenic in drinking water supplies. The primary pathway that exposes arsenic to humans is through drinking water.
