5 Municipal-Industrial Water Issues Analyzed

A water technology expert tackles high-profile and important topics currently affecting municipalities, industry, and the community at large.

Breakthrough Recyclable Polyimide Membranes Transform Wastewater And High-Salinity Water Treatment

Researchers have developed polyimide-based membranes for membrane distillation (MD) that overcome three persistent issues in membranes for water treatment and gas separations: the need for pore-forming chemicals that prevent recycling, performance degradation due to pore wetting and fouling, and the inherent trade-off between high water flux and selectivity.

Breakthrough Technology Is Good For Fracking — And The Environment

The Department of Energy (DOE) is funding a demonstration project that remediates acid mine drainage water, providing both source water and useful byproducts for hydraulic fracturing operations.

Maximize Uptime And Minimize Risk With On-Site Flow Meter Verification

A dedicated, manufacturer-approved verification system is the ideal solution for maintaining optimal performance of your installed base of KROHNE electromagnetic and mass flow meters.

Real-Time Heavy Metal Monitoring For Oil & Gas

Large, distributed water networks are not well-suited for conventional water monitoring processes which rely on manual sampling and lab testing. In particular, this midstream oil and gas company had a need to detect Iron, Selenium, and other heavy metals at a precise level comparable to a lab. In addition, it wasn’t feasible to manually test the entire water system at the requisite frequency. Finally, instrument reliability and unplanned downtime were an issue.

Optimizing Aeration Reliability In Food And Beverage Wastewater Applications

In addition to penalties for non-compliance, wastewater treatment plant (WWTP) operators in the food and beverage industry risk excessive losses caused by problems at the wastewater treatment facility.

Featured Profiles In Brewery Wastewater Success

Stories of real success with packaged pumping and wastewater treatment systems at breweries are explored, including for regulatory compliance and/or water reuse capabilities. Packaged pumping and treatment systems have helped hundreds of brewers meet their permits for local collection and/or direct surface discharge.

Webinar: Newterra's Dispersed Air Flotation (DAF)

Microfloat Dispersed Air Flotation (DAF) System is an effective, affordable, and reliable physical/chemical pre-treatment technology for removing up to 90% free-floating FOG, 60% TSS, and 30% BOD*– all at a much lower cost than traditional DAF systems.

Would You Like Some Free Green Energy With That?

Some of the world’s most environmentally efficient and profitable green energy technologies are being specifically tailored to the needs of the beef, poultry, pork, rendering and stockfeed industries.

Injecting Innovation Into The Food And Beverage Industry

Not all water treatment needs are the same. That’s why it’s imperative to work with those that understand the subtle dif­ferences that make each industry unique. For food and beverage companies, that means aligning with KLa Systems, a com­pany focused on oxygen transfer with a track record of innovation in jet aeration and mixing.

Straight Talk On Radiation

From time-to-time I write on topics that are related to water and wastewater as a "backgrounder" so that those involved in the field can gain a wider perspective and have available to them a cogent explanation minus jargon on various topics. By Dr. J.H. Wakefield

Is Your Water System Ready For Population Growth?

Utilities are faced with myriad threats looming in the future, but chief among them is increased stress from population growth. In Denver, comprehensive planning for that future is underway.

The Importance Of Clean Water, A Foundation For Green Hydrogen Energy Production

As the global economy starts fully integrating other sources of energy in addition to fossil fuel, solar and wind, green hydrogen is starting to gain momentum.

4 Safety Considerations For Anyone Storing, Handling, or Transporting Substances

Substances regulated or substances unregulated may ultimately impact the environment, health, and water supply of others. The following safety considerations are advised for those who store, handle, or transport potentially dangerous substances.

Design And Care Of Reverse Osmosis Systems, Part 2: Upstream Equipment

The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.

Legionella Conference 2018: Controlling This Deadly Bacteria Will Take A Village

Controlling Legionnaires’ disease will require a universal, preventive-based approach by a bevy of stakeholders ranging from building owners to hospital administrators, from public health officials to policymakers, and from scientists to water system engineers.

Cooling Tower And Process Water Treatment

The unique properties of hydrogen peroxide (H2O2) make it a good technology for keeping cooling loops, process water loops and heat exchangers clean from fouling that can occur due to various contaminants in the water.

Precision Agriculture Requires Precision Measurement

Devices ensure precision fertilizer application while reducing air and water quality issues.

Evaluating The Advantages Of Decentralized MBR Wastewater Treatment

Much of the progress on wastewater effluent quality under the Clean Water Act has focused on centralized facilities in larger cities. Now, decentralized systems are expanding options for municipalities, developers, and engineers to support high-quality wastewater treatment in locales that can’t sustain conventional septic systems or make it too costly to build or access centralized wastewater treatment plant (WWTP) or water reuse facilities.

Breakthrough Recyclable Polyimide Membranes Transform Wastewater And High-Salinity Water Treatment

Researchers have developed polyimide-based membranes for membrane distillation (MD) that overcome three persistent issues in membranes for water treatment and gas separations: the need for pore-forming chemicals that prevent recycling, performance degradation due to pore wetting and fouling, and the inherent trade-off between high water flux and selectivity.

The Importance Of Water Efficiency In Enhancing Economic Development Strategies Establishing water efficiency measures with commercial, industrial, and institutional (CII) sector partners has a lasting effect if positioned from a standpoint of cost savings, utility footprint reduction, and overall economic development benefits.

Vital Fire Suppression Line Remains Live While AVT EZ Valve Is Installed

A major Texas-based refinery provides significant feedstock flexibility and product diversity to the area’s operations. The plant dates to the early 1900s and following upgrades now produces more than 125,000 barrels per day. A vital element of any refinery is its ability to be constantly ready to respond to a fire, so when the refinery found an inoperable valve on its 12” carbon steel fire suppression line and was in need of a way to add a valve to their system without shutting down the line, their maintenance and repairs contractor, ISS, suggested installing an AVT EZ Valve.
