Digital Predictive Maintenance Drives Water Industry Productivity
The adoption of Industry 4.0 continues to gather pace, with industrial digitalization leading the way. The water processing industry in particular has seen a steady increase in digital adoption and the sector has in fact overtaken other industries. For example, water was one of the first industries to really make full use of predictive maintenance to extend the life of aging assets and improve operational efficiency. James Chalmers, Vice President, Global Water & Wastewater Sales at ABB, outlines the advantages of this approach.

AquaDiamond Cloth Media Filters Achieve 0.1 mg/L Total Phosphorus Limit
With the current national emphasis on restoring the water quality of America’s urban waterways, the City of Brockton, Massachusetts, Advanced Water Reclamation Facility (AWRF) wanted to stay ahead of the regulatory cycle – in particular, phosphorus discharge limits set forth by the National Pollution Discharge Elimination System (NPDES) program of the United States Environmental Protection Agency (U.S. EPA). For this region of the country, the U.S. EPA has proposed total phosphorus (TP) discharge limits of 0.1 mg/L.

Capacitance Level Switches Provide Reliable Water/Oil Interface Detection
There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.

White Paper: Stormwater Retention For A Modular Green Roof Using Energy Balance Data New York City stormwater is a major cause of water pollution in the harbor and estuaries. This is due to the vast areas of impervious surfaces (e.g., rooftops, pavements, sidewalks) that rapidly shunt runoff into the combined sewage overflow (CSO) system.

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.
