WASTEWATER MEASUREMENT RESOURCES

  • Treatment plant control systems are more vulnerable to computer hacks than ever before. What should utilities be doing to prepare themselves?

  • They did it again. Seemingly every year WEFTEC breaks records for size and attendance, and 2014 in New Orleans was no exception. There was a lot to choose from, but I picked my favorite innovations to highlight in what has become another annual tradition — Water Online’s “Top 10” from WEFTEC.

  • At a wastewater treatment plant in Stockholm, Sweden, each aeration basin has several diffuser systems. Each diffuser system requires individual air flow monitoring and independent control. The air flow pipes leading to the diffusers typically do not have much straight run of pipe. This makes accurate measurement of the air flow more difficult. In addition, the air flow coming from the compressors is inconsistent

  • When it comes to water quality, water districts are pressured with reducing costs, energy usage, and repairs, all while providing fast and flawless results. This client needed advanced and competitive software to address their planning and management setbacks.

  • Denver Water serves 1.4 million people in the city of Denver and the surrounding suburbs. It is the largest — and oldest — water utility in the state of Colorado and its service area covers more than 335 square miles.

  • As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas.

  • The City of Shelby, Ohio recently upgraded its activated-sludge wastewater treatment plant to double its capacity to 5 MGD, while expanding its capability to treat and disinfect combined high-volume stormwater and wastewater flows generated by wet-weather conditions.

  • Discover how Contact Automation deployed a FreeWave solution to transform communications capabilities of Sylvan Lake, Canada's water and wastewater operation. 

  • We hear many paradigms in the design world — design for manufacture, design for assembly, etc. What we don’t often hear is design for operation.

  • By comparing four types of aeration blowers designed specifically for wastewater treatment, this white paper educates engineers on how to develop a selection process best suited for their operation. The paper focuses on minimizing energy consumption and total cost of ownership of the aeration blower system. Download this white paper for a detailed comparison of real operating data on aeration blower technology. 

WASTEWATER MEASUREMENT SOLUTIONS

  • Understanding The Different Phosphorus Tests

    In wastewater treatment, phosphorus testing can quickly become confusing. For example, there are three different tests. So, which test was performed? Test results can be displayed in two different forms. So, which form was utilized? Tests can measure both particulate and dissolved phosphorus. So, was the sample filtered?

  • Ortho-Phosphate Analyzer

    Introducing the NP6000sc, the latest evolution in Hach® Phosphate Analyzers. As the next evolution in nutrient monitoring, combining the trusted reliability of Phosphax with cutting-edge innovations to address your biggest challenges.

  • Measuring Low Limit Values For Orthophosphate Using The Phosphax Sc Low Range

    Tightening phosphate limits require high-precision monitoring to ensure compliance and economical chemical dosing. Refined photometric methods now offer superior accuracy at ultra-low ranges, providing the stable data necessary to optimize wastewater treatment processes.

  • XD Spectrophotometers

    The XD 7000 and XD 7500 Spectrophotometers combine a state-of-the-art optical system with ease of use and flexibility for a wide range of water testing applications. 

  • BOD Determination

    The BD 600 is a respirometric system for the determination of Biochemical Oxygen Demand (BOD). Save time, reduce the potential for errors and easily interpret data to help make process control decisions for your plant.
