PASS is a workflow for understanding sewer system conditions quicker, with fewer resources. 

In 2004, Headworks Inc. was selected to supply 22 screens to the George W. Kuhn Retention Treatment Basin (“GWK RT Basin”) located in the Detroit Metropolitan Area of Michigan.

The RESILIO project has helped Amsterdam repurpose rooftops as smart blue-green roofs to reuse rainwater and prevent localized flooding. This project, along with other sustainable water initiatives like the Amsterdam Rainproof program, continues to position the Netherlands at the forefront of water management.

Tube settlers use multiple tubular channels, which are adjacent to each other and sloped at nominal 60˚ angles, to form an increased effective settling area. This configuration allows for a shorter particle setting depth, and as the tube settler channels collect solids, they form a compact mass that promotes the solids to slide down the channel. Tube settlers are an inexpensive method of upgrading existing clarifiers and sedimentation basins by allowing increased flow rate and/or improved performance. They can also reduce the footprint of new clarifier construction.

In the last forty years, a quiet revolution has occurred in our industry. This revolution is the result of new generations of joint restraint products that make it possible to quickly and safely restrain fittings at bends, dead ends, tees, valves, and reducers without the need for concrete thrust blocks or tie rods. These joint restraint products turn the pipeline into its own thrust block. The key to utilizing these new products is the understanding and proper application of the pipeline restraint design theory.

Ozone systems build resilience into water treatment. They ensure utilities remain chemically self-sufficient, allow fast recovery from power outages, and handle rapid water quality shifts.

In this article, take a look at types of dewatering boxes, benefits, and their applications for various projects.

The Archer Daniels Midland Company (ADM) requires full-scale nonchemical disinfection and dechlorination treatment of RO feedwater to the boiler which supports their cottonseed processing facility in Lubbock, Texas.

This article focuses on the use of electromagnetic flowmeters in the W/WW industry. It also covers Endress+Hauser’s capabilities to manufacture electromagnetic flowmeters from 1/12” to 120”, calibration, the company’s new innovative sensor with multiple sensing electrode pairs and verifying calibration in place after installation.

Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

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.

Strongly loaded organic industrial waste water, i.e. from sugar- or paper-factories, need to be pre-treated before determining the BOD value.

Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

There are many different joints that can be found on waterworks pipeline components. This paper focuses on the three most common joints.

Limits of Detection and Quantitation are key to understanding analytical instrumentation capabilities, especially when non-optimal process control can lead to damage of sensitive equipment due to insufficiently accurate readings.

The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.
