02.23.24 -- Dish Pods, Laundry Sheets Face Ban Over Microplastic Contamination

With the recent release of the Lead and Copper Rule Improvements, and less than nine months to submit your preliminary inventory, 120Water is unpacking what water utilities need to know to get the job done. We’ll discuss how the proposed LCRI impacts your compliance program plans and what tools are available to set you up for success. Click here to learn more.

Everyone wants pathogen-free drinking water, and adding chlorine is a great way to get it. Unfortunately, the dirtier a water treatment plant’s (WTP’s) raw water inflow — in terms of natural organic matter (NOM) or microbial organisms — the more disinfection byproducts (DBPs) the chlorination process will generate in the form of trihalomethanes (THMs) and haloacetic acids (HAAs). 

Most governments have strict regulations which require regular testing of water samples to prevent lead contamination. Despite this, challenges remain with lead in drinking water in many parts of the world.

When it comes to pH measurement in water and wastewater treatment, there are two focal points for the word “standard” — one is a compliance-related state or federal water quality specification; the other is a specific fluid used as a calibration reference point to ensure pH instrumentation accuracy. Here is why both are important and how they affect the best pH measurement outcomes in both areas.

Part of the challenge in wastewater metering accuracy has as much to do with the flow profile of wastewater running through the meter as it does with the composition of the wastewater itself. Here is how installing a simple static device in the tight confines of a lift/pump station can alleviate the twists and swirls of pipeline turbulence in as little space as three pipe diameters.

Read the full case study to learn how the installation of the three Flygt horizontally mounted dry pit, flood-proof NZ-3171 submersible clog-free pumps immediately offered a 25% boost in efficiency at a lift station in Manitoba, Canada, after a motor had shorted out due to excessive moisture and could not be replaced.

Non-revenue water (NRW) and other information gaps that have significant impact on operating costs are causing many water distribution utilities to seek affordable ways to gain greater insight into flow data. In this Q&A, Barry Spiegel of McCrometer describes how full-profile insertion (FPI) electromagnetic flow meters (mag meters) can provide relief, without breaking the bank.

In late 2005, the city of Newberg, OR, decided to upgrade its water treatment plant disinfection process from gas chlorine to onsite hypochlorite generation (OSHG) in an effort to simplify operations and increase operator safety. The plant produced an average of 2.5 million gallons per day (MGD), with a peak capacity of 5 MGD.

There are many types of clarification options on the market, including circular clarifiers and ballasted clarification systems — but this article will focus on rectangular clarifiers, or what many industry professionals refer to as chain and scraper systems.

Of all the challenges wastewater treatment plants (WWTPs) face, screening debris from the flow at the headworks is one of the first encountered. Until recently, that has involved choosing one screen size to accommodate both average and peak flows or installing two different screen sizes.
