How To Improve Anaerobic Digestion And Turn Sludge Into Renewable Energy
Anaerobic digestion is a critical element in a sludge management plan for wastewater treatment. Its role is to kill any pathogens in the raw sludge, produce a more desirable final product, and enhance the amount of biogas/energy generated by the process. The main issue is how best to improve the sludge quality without incurring excess costs.

AVT™ EZ VALVE® Ensured The Water Kept Flowing At A Hospital
When a 40-year-old booster pump servicing Ochsner Health Centre in Baton Rouge, La began to falter, officials knew that had to resolve the issue fast. COVID-19 had left the hospital at full capacity so turning off the facility’s water was not an option. The pump’s existing control point was inoperable, so a new valve needed to be installed.

Reduce SBR Maintenance Costs With Jet Aeration
Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

Nitrogen-Reduction Treatment Systems For Long-Term Operations
The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

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.
