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.
Municipal wastewater operations require significant energy to operate, but the biogas produced solely through anerobic digestion of sludge isn’t typically enough to offset the electricity and heat load demand at plants. Advanced anaerobic digestion technology, however, can change the equation so wastewater treatment plants can get closer to energy neutrality and in some cases even generate an excess.
Colleges and universities are working harder than ever to account for their resources, but getting a handle on steam production can be tricky. A growing number of schools are banking on one solution for better insight.
The technological innovation that powers water and wastewater treatment processes — like new membranes for produced water cleanup or desalination technology for stressed water systems — is largely what drives the industrial and municipal treatment industries forward.
As South Africa commemorates National Water Week from March 17 to 23 to highlight the scarcity of this vital resource, municipalities and utilities around the country are increasingly turning to technology to help them with both conservation and expanding accessibility to more communities.
Potable reuse offers a massive opportunity to recover water from the wastewater process, but projects face a variety of barriers to getting off the ground. Most successful early adopters engaged early with their constituents and implemented smaller-scale demonstration projects that were accessible to the public to prove the technology and process.
CU engineering students tackle real-world design challenges at new Denver Water treatment plant.
Residents of an Iowa town were told not to drink their tap water this month when dangerous levels of manganese were found in the supply. And most concerning may be the fact that nobody seems sure how long the contamination has been affecting residents.
The membrane bioreactor industry has matured past the point of being an experiment or a niche technology. Advancements, as well as more recent adoptions by high-profile users, are providing wastewater treatment plant operators with more incentive and a better business case to retrofit their systems.
While some water quality parameters may get more attention in industrial settings, few are more critical than conductivity. Understanding conductivity monitoring for industrial applications — where it is needed, how it works, and how to leverage the appropriate instruments and standards in order to pinpoint it — will unlock huge gains in efficiency, effectiveness, and regulatory compliance.
The City of Santa Fe has achieved a wastewater first, establishing a financing model that may offer a new revenue approach for other cities throughout the country.
A growing number of wastewater treatment plant leaders are banking on newer technology to tap into previously unclaimed resources at their sites while addressing pressing issues. By looking at the process through a different lens and raising the bar when it comes to overall objectives, it is possible to shift facilities from being a cost center toward a revenue generator.
Precise water quality is critical for municipal water treatment operations, but many industrial applications have even more rigorous requirements, regulations, and guidelines to follow. The energy, pharmaceutical, food processing, and other industrial fields require exact water quality in order to function efficiently.
When it comes to providing wastewater treatment plant (WWTP) solutions for isolated, low-volume applications, it is true that good things can indeed come in small packages. The execution of membrane aerated biofilm reactor (MABR) technology in compact self-sufficient arrays — including transportable containerized units — now offers wastewater treatment with enhanced nutrient removal for stand-alone applications and remote points of use.
‘Resilience’ — in terms of delivering resilient water and wastewater services focused on preventing floods and pollution — is one of the key words when it comes to preparing for AMP7. As an industry, we can do this by implementing monitoring systems that provide robust and accurate data that then enables the water company to effectively manage and measure the health of their network and its assets.
After a long period of totally inadequate funding for critical water projects, the tide appears to be turning and funding is becoming more readily available.
A wide range of industrial operations rely on cooling systems to function. And, in turn, these systems require cooling water to function. So, it stands to reason that a wide range of water treatment issues need to be considered and addressed so that cooling water system upsets are avoided and everything continues to run as it should. Oftentimes, an efficient industrial operation depends on efficient monitoring and treatment of cooling water.
For those who appreciate the old maxim about catching more flies with honey, the logic of creating a more favorable biological environment for better biological nutrient removal (BNR) makes perfect sense. Worldwide implementations of flat-sheet membrane aerated biofilm reactor (MABR) technology are doing exactly that — in less space, with less energy, and with lower operating expenditure (OPEX) for aeration and chemical treatment. Here’s how:
Industrial operations across the gamut leverage boiler water, the liquid that passes through a boiler and is converted into steam, thus powering operations around the world. But not all of them do as much as they could to ensure peak boiler water efficiency. Through the proper treatment considerations and quality measurement knowledge, every industrial player can make the most of this central process.
Large-scale water-reuse treatment plants have had sustainable impact in populated areas where the volume of water to be treated and reused in a concentrated area makes them practical. Today, the flat-sheet membrane aerated biofilm reactor (MABR) technology that is delivering high-quality wastewater treatment to remote locations is poised to realize the promise of sustainable water reuse in those same locations.
Wastewater treatment plant (WWTP) designers and decision-makers tasked with finding more cost-effective performance for challenging applications want new options. Here is how flat-sheet membrane aerated biofilm reactor (MABR) technology tweaks the chemical and biological functions of conventional activated sludge (CAS) processes to reduce energy consumption and operating expenses (OPEX) in demanding applications.
While pervasive drought in the American Southwest continues to present myriad problems for local water systems, it is also a dynamic opportunity — at least for private companies looking to capitalize on the scarcity.

Secondary metabolites of algae — including algal toxins and taste and odor compounds triggered by a harmful algal bloom — can find their way into source water, creating the risk that they will ultimately reach the water treatment plant to cause water-quality problems. Here is a checklist of considerations for mitigating those effects through cost-effective oxidation, or combined oxidization processes, across a variety of source water conditions.
Understanding the nature of harmful algal bloom causes, effects, and remediation strategies is key to choosing optimal water treatment plant technologies for improved resilience against this emerging threat to water quality. Whole-cell removal of algae via dissolved air flotation technology helps in maximizing physical removal of intact algal cells and biomass and reducing disinfection byproduct potential.

Changing climate and other environmental conditions are intensifying the frequency and severity of harmful algal blooms (HABs). Here are important guidelines to understanding HAB causes and impacts to potable water treatment plants — including dealing with the algal biomass, remnants of decaying algal cells, and especially the secondary metabolites that the algae produce, such as taste and odor compounds and toxins.
