WASTEWATER MEASUREMENT RESOURCES

  • As a leader in the water industry, Gwinnett County Department of Water Resources (GCDWR) aims to provide superior water services at an excellent value. The multi-award-winning utility has been recognized both statewide and nationally for excellence in water production, wastewater treatment, infrastructure development, and customer satisfaction. GCDWR operates and maintains two water production facilities; three water reclamation facilities; more than 200 pump stations; and nearly 8,000 miles of water, sewer, and stormwater pipes that provide essential services to more than 900,000 people each day.

  • The conceptual design output you get from the TDG will inherently have value -- the TDG already saved time and effort in creating the resulting conceptual design compared to traditional design approaches.

  • Ever since Coriolis flow measurement technology achieved mainstream appeal, industry has been fervently striving to take advantage of its benefits. And while Coriolis is clearly a highly advantageous solution for many crucial flow measurement applications, it is not without flaw.

  • Microorganisms can wreak havoc in industrial processes in a number of ways – from slime formation that causes paper breaks and excessive downtime in papermaking facilities, to costly recalls of spoiled final product. Consequently, an effective microbiological control program, which includes accurate and reliable monitoring, is critical for maintaining an efficient process and final product quality.

  • When water and wastewater plant operators can’t get accurate flow measurements or analytical readings — or lack confidence in their instruments’ readings — it creates challenges with the process. When substandard water goes to homes and causes a boil order, or discharge pollutes a lake or reservoir, the resulting bad press, fines, and potential lawsuits erode public confidence. Avoiding these kinds of problems is rooted in good preventive maintenance habits.

  • Explore how machine learning works and how it compares to hydraulic modeling.  

  • I became interested in water and the Internet of Things (IoT) several years ago when I had a below groundwater leak at home that resulted in a large water bill. Since I live in the Silicon Valley, CA, the high tech capital of the world, I thought there should be a better way to track water usage so problems can be identified and solved sooner.

  • Water Online’s “Math Solutions,” presented by wastewater consultant and trainer Dan Theobald (“Wastewater Dan”), instructs operators on poundage calculations.

  • Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

  • 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.
