The Importance Of pH Measurement During Industrial Treatment
The Importance Of pH Measurement During Industrial Treatment

Nearly every industry requires water and wastewater treatment to some degree. From food and beverage to pulp and paper operations, influent and effluent must meet certain conditions to adhere to regulatory and/or performance requirements, and water used during the process must conform as well.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Concord, Massachusetts WWTP - A Low-Cost, 20-Year Solution To Ever-Tightening Phosphorus Limits
    Concord, Massachusetts WWTP - A Low-Cost, 20-Year Solution To Ever-Tightening Phosphorus Limits

    Prior to 2007, Concord, Massachusetts wastewater treatment plant operated under a NPDES permit that allowed a seasonal phosphorus limit of 0.7 mg/L. But with the issuance of a new five-year permit with a phosphorus limit of 0.2 mg/L and the probability that future limits could reach as low as 0.05 mg/L, Concord needed a treatment solution that would be reliable and cost-effective today and over the long term.

  • Accurate Gas Flow Measurement Improves Water Disinfection Process Efficiency
    Accurate Gas Flow Measurement Improves Water Disinfection Process Efficiency

    Many of today’s large urban water treatment plants rely upon sophisticated chlorination processes in order to provide clean, sanitary water to millions of consumers in the US and around the globe. The efficiency and cost-effective operation of chlorination processes in water treatment facilities can be significantly improved with the installation of flow meters that accurately measure the flow of chlorine gas in the treatment process

  • Pumps Reduce Costs, Improve Reliability, And Deliver Outstanding Energy Efficiency For Ohio WWTP
    Pumps Reduce Costs, Improve Reliability, And Deliver Outstanding Energy Efficiency For Ohio WWTP

    An aging lift station in Marietta, OH, was the first of 12 stations to be upgraded as part of a capital improvement plan at the city’s wastewater treatment plant (WWTP).

  • N-Pumps Resolve Clogging Problems, Reduce Energy Consumption
    N-Pumps Resolve Clogging Problems, Reduce Energy Consumption

    In the past, a lift station operation in Ohio had to send crews out daily to unclog one or more pump stations in the county service area. Chronic blockages were attributed to pump design, byproduct grease from restaurants, and medical waste from assisted living and nursing homes along the lines.

    Biological Water Treatment: Only The Best Instruments Are Good Enough

    Vallviks Bruk AB, located about 200 km (125 miles) north of Stockholm, produces softwood kraft pulp and chemical pulp for export. Some years ago, increased environmental requirements led to a major investment in a biological treatment plant. Read the full case study to learn why ABB instrumentation was an obvious choice when the Swedish pulp producer Vallviks Bruk AB built a new plant for biological water treatment.

  • Plant's Aeration Output Increased While Electricity Is Decreased

    Located in New Haven County, Connecticut, in the eastern USA, the wastewater treatment plant in Meriden has a design inlet flow of 43,911 m3/day (11.6 mgd) with a maximum inlet flow of 143,386 m3/day (38.0 mgd). Upgraded in the 1960s and 1980s, the plant has been in existence since the 1800s.

  • Refinery Turns To Thermal Mass Flow Meter
    Refinery Turns To Thermal Mass Flow Meter

    An independent Midwest refiner operates refineries in multiple states with a combined crude oil processing capacity of more than 500,000 barrels per day. The company recently approved a project to improve the safety of its plant and reduce its costs for nitrogen gas used for tank blanketing. Read the full report to learn more.

  • Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon
    Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon

    Special precast box culverts were used for one of the most significant segments of the $25.8 million emergency water restoration project, designated by the NRCS, known as the Cache Water Restoration Project (CWRP). The CWRP project involved the reconstruction and improvement of approximately six miles of mostly open, unlined channels that make up the Logan and Northern, as well as the Hyde Park and Smithfield canals. The project incorporated new precast pipeline, box culverts, a section of pressurized pipe, metering systems, turn-outs, head gates, and improved maintenance access.

    How Data And Nature Can Combine To Help Small Wastewater Treatment Plants Address Huge Hauling Costs

    It is no secret that the number of landfills has been steadily decreasing across the United States. As more and more cities adopt ‘zero waste to landfill’ sustainability goals, the number of landfills has shrunk from 6,326 in 1990 to 1,738 in 2015. Decreasing landfills has meant increased waste hauling costs for wastewater treatment plants (WWTPs) as sludge travels farther distances to reach landfills.
