Refinery Treats Groundwater Contamination While Saving Precious Facility Space

A large, Midwestern oil refinery installed two identical, 110’ diameter S&L Model R OXIGEST® treatment systems to solve a groundwater treatment problem on-site. Each plant incorporates aeration, clarification, and effluent holding, treating peak flows of 7.2 MGD combined; 4.3 MGD in each plant.

City Of St. Cloud Relies On Thermal Flow Meters For Digester Biofuel Co-Gen Power Process

The City of St. Cloud, Minnesota, straddles the Mississippi River near the center of the state a little more than 65 miles north of the twin cities of Minneapolis-St. Paul. The city’s forward thinking staff began looking for sustainable green energy solutions in 2003. After planning and initiating a series of projects over several years, the site is today producing renewable energy with a 20 kW rooftop solar array, a 220 kW solar array and biofuels electricity generation.

A Fracking Coverup?

I’m not inclined to pick on the EPA, but in the wake of the recent report that they overstepped their authority on stormwater regulation, I saw that The Associated Press did an exposé charging the EPA with suppressing information on hydraulic fracturing’s link to drinking water contamination.

Choosing The Right Instrumentation For Produced Water Treatment Systems

A range of devices are required to cost-effectively manage the lifecycle of produced water. Operators often face the question of which process instrumentation is the right fit given the unique requirements of their application.

The Multiple Uses For Heat Exchangers In Brewing

There are numerous uses for heat exchangers in breweries — from cooling, pasteurizing, and fermenting products to efficiently dealing with waste streams such as yeast slurry. Compared to other methods of heating, heat exchangers can be much more energy-efficient, providing both environmental and economic benefits.

How To Balance Dissolved Oxygen Levels For Maximum Efficiency

While dissolved oxygen (DO) levels are critical considerations in aerobic wastewater treatment processes, not every application maintains a consistent level of demand. How industrial wastewater treatment plants (WWTPs) track and fulfill those needs make a big difference in the optimum performance and cost-efficiency of their operations.

Wastewater Transformed From Problem To Profit

Latin America and the Caribbean have rich potential to replace fossil fuels with green energy as technology delivers profitable and environmentally friendly alternative sources of heat and electricity generation.

Dairy Collective Reaps Green Energy And Environmental Benefits With Anaerobic Wastewater Technology

One of the United States’ newest dairy processing plants features advanced wastewater treatment technology that not only radically improves biomass recovery and effluent quality, but also harnesses green energy from waste streams to drive production processes and reduce its carbon footprint.

AquaSBR Sequencing Batch Reactor: Food And Beverage Industry

This application note explores Sequencing Batch Reactor (SBR) systems that have been installed worldwide in a variety of applications, ranging from a few gallons per minute (GPM) to thousands of GPM.

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.

Rounding Up The Water, Clean Energy, And Climate Bills In The 85th Texas Legislative Session

We’re entering the home stretch of the 85th Session of the Texas Legislature.

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.

Cloth Media Filtration Removes Coal Ash And Coal Fines At Power Plants

Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.

Clogging Issues Solved With Outstanding Pump Efficiency

The horizontal, dry-installed pumps at the network pumping station Zell am See were clogging at least 2-4 times a week, also during weekends. Consequently, the pumps had to be lifted and the blockage removed. A high amount of sanitary items and incontinence adult diapers from the nearby hospital were the root cause for the clogging. Read the case study to learn more.

Compared to other methods of heating, heat exchangers can be much more energy-efficient, providing both environmental and economic benefits.

Cost Benefits Of Process Water Disinfection Via UV Light Sterilizer Technology

For the sake of the productivity and quality of products, as well as the proper upkeep of process equipment, treating process water prior to use is very beneficial, if not vital. One step in treating process water is often disinfection. While there are several chemical options for disinfection, ultraviolet technology can provide several key cost benefits for onsite treatment systems.
