The community of Kinglake West was on a waiting list to receive government financing for a new sewer system when, in 2009, a disastrous fire swept through the area. The damage was so extensive that funding for a wastewater collection system was expedited. The new system needed to be up and running as soon as possible, without being an undue financial burden to homeowners.

A municipal wastewater treatment plant investigated a sudden increase in fecal coliform exceedance events.

Two things are perhaps certain about septage: it is highly variable; and, by its very nature — spewing odorous compounds and elements that can cause disease — it is ‘objectionable.’ Or is it?

To combat drought, Abilene, Texas, implemented a reuse system utilizing O₃​ + BAC to remove trace organics. This solution met strict standards, ensured water resilience, and proved more cost-effective than AOP alternatives.

When the Kearney, MO wastewater treatment plant began plans to upgrade its headworks they choose JWC Environmental’s Brushless Finescreen Monster to replace its old coarse screen.

Lamella, or lamellae, is a term frequently used when discussing sedimentation and clarifier design. Lamella clarifiers can be used in applications ranging from municipal water and wastewater treatment to various industrial applications. The primary benefit of utilizing lamella clarifiers over conventional clarifiers is reduced footprint. However, the term “lamella” is often used too broadly in the industry without clear intention.

These equations and soil parameters are an effort to provide the piping system designer with conservative techniques and parameters for the design of underground restrained joint piping systems. 

Wastewater treatment plants (WWTP) are facing many challenges. Permits on nitrogen and phosphorus in the effluent water are progressively becoming stricter in order to protect surface waters from eutrophication. At the same time, plants are required to reduce both energy and chemical consumption and are often challenged with limited time and staff. In total, they are required to do more with less. In order to meet these challenges, a plant with a Sequencing Batch Reactor (SBR) in Green Lake, Wisconsin was upgraded with an advanced process control system – the OSCAR process performance optimizer with NURO controller.

Are you not getting the aeration performance you expect? Perhaps you’re not even aware that your system is lagging. In this age of doing more with less — practically a mandate considering high water-quality demands coupled with tight municipal budgets — operational optimization is essential. Since mechanical aeration is a cornerstone of successful wastewater treatment, it’s a natural place to focus your optimization and troubleshooting efforts.

A mid-size water system in the southeast was looking to pull together multiple measurements in a single panel. After reviewing off-the-shelf solutions, they realized there was nothing that met their requirements.

Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.

This application note explores how Greenline pumps enhance odor control systems by delivering precise chemical dosing for odor mitigation and pH control, ensuring cleaner air and improved quality of life.  

In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

The most common level application in the water and waste water industry is the infamous wet well. With its line-of-sight measurement technology, rugged sensor, narrow laser beam and virtually nonexistent maintenance requirements or on-site calibration, ABB’s LLT100 laser level transmitter answers most concerns related to wet well level measurements and makes it easy to calculate what could amount to a substantial return on investment.

The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

As flooding increases along coastal and river-adjacent communities, the need for low-cost, reliable monitoring and warning systems has become a critical factor for managing these issues in real time, without requiring major infrastructure overhauls.

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?

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company
