Eliminating Sludge Islands In Your Wastewater Lagoon
Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons.

Rightsizing Blower Installations For Optimum Performance
In regulated wastewater treatment plant (WWTP) environments, which require 100 percent blower system redundancy to satisfy the most extreme operating conditions, it can be easier to meet demanding physical thresholds than it is to refine energy performance to the ideal minimum. Here are some guidelines for covering all the bases — estimating the potential payback of balancing blower type, size, and turndown capacity while making the evaluation exercise worth the effort.

Top 5 Considerations When Choosing A Flight Scraper For Your Rectangular Clarifier
What should you consider when planning to replace the flights in your rectangular clarifier? Flights are also known as scrapers, c-channels, flight boards, drag flights, and sludge pushers. Regardless of what you call them, they serve the same purpose. Flights convey settled solids to a hopper or collection pit and push surface debris into a scum removal device in a straight-line clarifier system. Although flights may all seem the same at first glance, there are some key characteristics to think about when evaluating which type you may need for your chain and scraper system.

Self-Cleaning Trashracks Help Keep The Power On For New Zealand Hydroelectric Plant
Hydrogeneration is the dominant source of energy in New Zealand, providing approximately 70% of total electricity. The Hornwort, a submersed, free-floating perennial which can reach nearly 20 feet of height above water, has invaded New Zealand’s waters. The plant quickly proved to be an issue for Genesis Energy at the Tokaanu Power Station, a 240 MW hydroelectric power station.

Oldest Town In West Virginia Adopts Modern Wastewater Treatment System
As with many of today’s aging plants reaching 30+ years of service, the outdated technology and in-efficiencies had placed a burden on a West Virginia town and its officials. The system was no longer able to accommodate the community’s growth or meet the effluent requirements on nitrogen and phosphorus.

Step Screen Replaced By Headworks
In May 2008, Portland Water District installed 3 step screens in each of their 3 channels and in only 7 years of use, were facing maintenance & performance issues with the step screens. These screens were also affecting downstream processes.

TASKMASTER® Grinders Play Central Role In Biofuel Production
A biogas station in Poběžovice, the Czech Republic could be a prototype for what the future holds for the production of energy from renewable sources. Built by the Spin Plzeň company, the facility is located on the grounds of an agricultural farm focused on pig breeding. The station processes a combination of biodegradable waste to produce the biogas. The main component is 100 m3/day of liquid pig manure which is combined with maize silage and slaughterhouse waste.

Ion Exchange Resins Reduce Pollution From Refineries
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.

Advances In Paper-Based Devices For Water Quality Analysis
Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.

With the rise of water scarcity, environmental regulations, and corporate sustainability mandates, produced water treatment has become a strategic imperative for industries far beyond oil and gas. It is one of the fastest-growing segments in the water treatment industry, which has emerged as an amalgamation of environmental stewardship, regulatory compliance, and technological innovation.

People around the globe are trying to figure out how to save, conserve, and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater. But for all the clean water they may produce, those processes leave behind a type of liquid called brine. I’m working on getting the water out of that potential source, too.

As water systems become more circular and complex, understanding and managing the subsurface — the hidden half of the water cycle — is becoming a critical enabler of resilience. This article explores the key trends shaping this new reality, from tackling “forever chemicals” to the water strategies redefining heavy industry.

The White House has finalized plans to roll back rules under the National Environmental Policy Act (NEPA), narrowing its focus and limiting what the current administration claims are needless delays for federal approval of water, energy, and other infrastructure plans. For water and wastewater utilities, the changes could speed up permitting for critical projects, although experts warn the tradeoffs could do more harm than good.

Traditional sewer systems, while effective, often require significant capital investment, invasive implementation measures, and complex maintenance. As a result, innovative decentralized wastewater solutions are necessary to address the needs of communities or commercial areas in need of wastewater service. One such solution is the liquid-only sewer (LOS) system.
