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.

It’s been two months since EPA released its much anticipated draft report on hydraulic fracturing, and organizations like ours are busy preparing their official comments, which are due at the end of August. But based on what we have learned so far and what has been written in the media, it’s important to spend some time on what the report said — and didn’t say — and what it all means.

A new study led by researchers with Colorado School of Mines exposes limitations with the current methods used to detect chemicals in oilfield wastewater and offers solutions to help regulators make better decisions for managing this waste stream.

You cannot produce oil without water, because water is present naturally in both onshore and offshore oil reservoirs. This naturally occurring water is called produced water. Produced water has a simple to complex composition that is variable, and it is considered as a mixture of dissolved and particulate organic and inorganic chemicals (Al-Ghouti et al. 2019) with an average of 7 to 10 barrels of produced water being generated for each barrel of oil during the course of an operation (Guerra, Dahm, and Dundorf 2011).

A thief hatch allows access for measurement, but if left open it can allow hydrocarbon vapors to escape into the atmosphere as fugitive emissions. 

California water reuse program provides multiple benefits, serving as a model for other municipalities.

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.

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.

American Laboratories, Inc. is a leading manufacturer of enzyme products for many food, dietary supplements, nutritional and industrial applications. The company has grown steadily, currently operating three facilities in Omaha, Nebraska. To keep pace with this expansion, the company realized, some years ago, that a more efficient way to process the enzyme material was necessary. After examining their options, they made a decision to purchase a Franklin Miller DELUMPER® Crusher 1077 S4.

Arsenic in water is one thing, but arsenic in beer? This is getting out of hand. While the drinking water supply is clearly much more of a concern than the beer supply, the sobering fact is that arsenic, a known carcinogen, is far too prevalent in the environment.

A look at the market dynamics and drivers for ultrapure water treatment reveals multiple industries with growing demand, including one that stands above the rest.

Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. The final article of this three-part series will address RO system operation and maintenance best practices.

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.

By harvesting heating, ventilation, and air conditioning (HVAC) condensate, industrial operations can take advantage of a cool, convenient source of clean water.

Power Generation plants produce electricity by converting one form of primary energy (nuclear or non-nuclear) to motive power in order to drive generators and produce electricity.

Nutrient pollution is one of America’s most widespread, costly, and challenging environmental problems. This pollution can occur when excess amounts of nutrients, such as nitrogen and phosphorus, run off from land into streams, rivers, lakes, and other water sources. To help water quality managers reduce nutrient pollution, EPA researchers developed the River Basin Export Reduction Optimization Support Tool (RBEROST), a regional online tool currently available for the Upper Connecticut River Basin that provides low-cost solutions to meet nutrient load targets.

With Jeff Bezos announcing that he will be donating most of his wealth to philanthropic causes during his lifetime, I decided to repost my 2018 open letter to him on why his philanthropy should be directed towards water issues.

Cooling towers and chillers can be damaged by impurities in the water they use. Using carefully chosen chemical metering pumps can treat the water and prevent issues such as biological growth, corrosion, and scaling.

Level monitoring systems has successfully triumphed every implementation. Their deployments allow the users to measure the level of liquid stored in a container of any shape, size, orientation, or material. Powered with the advanced telemetric technology of Internet of Things, these systems measure liquid level without making any contact with the liquid and transmit the readings to a comprehensive platform suite.

Per- and polyfluoroalkyl substances (PFAS) are a group of an estimated 5,000 man-made fluorinated chemicals that have been used, since the 1940s, in the manufacturing processes of various consumer products and industries. PFAS are widely used, especially because of their oil and water repellency and temperature and chemical resistance.

America’s hazardous waste management program ensures the safe management of hazardous waste from the “cradle to the grave”. Many of these regulations were developed more than three decades ago, so it is important we ensure they continue to effectively protect human health and environment into the future.

As nutrient pollution increases the incidence and severity of harmful algal blooms, it is obvious and important to point mitigation practices toward a prime culprit — the agriculture industry.
