Recent technological developments now enable high-accuracy total phosphorus measurement in near real-time, on-line, that reliably matches lab results.

Our wastewater data holds valuable insights that signals when a community is sick, sad, or polluting. It also offers important signs for when life is getting better. Technology has improved enough to allow wastewater engineers to test and evaluate wastewater for community and environmental insights.

The Lariana Depur wastewater treatment plant in Fino Mornasco, Italy, treats wastewater from multiple textile manufacturers in the Como region, known as the heart of the textile industry. Since 1994, ozone has been used effectively as a polisher to remove the dark blue-purple color — the result of the dyes used in the textile dyeing and printing process — from the water.

As industries expand, they typically need to increase the capacity of their wastewater treatment facilities. Increasingly stringent regulatory requirements, such as lower nitrogen limits, may also signal the need to boost treatment capacity. Installing additional tanks and larger equipment not only adds capital costs but increases operating costs as well.

Hopewell Water Renewal (HWR) is a 50 MGD secondary wastewater treatment plant that treats the wastewater from local industries and domestic sources of the Hopewell, VA area. The plant began operating in 1977 and treats approximately 85% industrial waste. The facility achieves the treatment permit requirements for both BOD and TSS; however, treatment regulations have changed over the years and now require the removal of nutrients. HWR discharges effluent into Gravelly Run, a tributary of the James River and Chesapeake Bay Watershed.

Learn about a solution that employs a combination of grinding, solids removal, washing, and dewatering, and enables a typical septage truck to unload in 5 to 15 minutes. 

Communities are facing decisions on how best to upgrade aging stormwater infrastructure and build new  infrastructure to lessen the impacts of stormwater runoff. As communities make these decisions, they need tools to assess their options in order to determine the most cost-effective approach.

Membrane bioreactor (MBR) systems represent a sophisticated technology in the domain of wastewater treatment, offering superior effluent quality through an integrated process of biological degradation and membrane filtration.

To sustain the environment and smart community growth while protecting public health, engineers, municipal health officials, and regulators need innovative wastewater treatment solutions. The latest evolution of decentralized systems can efficiently handle residential and commercial daily flows and are a cost-effective alternative to the large, centralized wastewater treatment plants of the past. 

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.

A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

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

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 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.

We arm farmers with mission-critical water data to help enhance crop yield and taste. KETOS delivers valuable insights for fluctuations in deficiency and toxicity.

This application note explores the importance of maintaining a delicate balance in reverse osmosis systems to protect RO membranes.
