It wasn’t so long ago that city rivers were some of the more polluted bodies of water on the planet. In 1969 for example, the Cuyahoga River famously caught fire after years of unabated pollution, spurring an environmental movement to clean up the nation’s waterways.
Veolia entered into a DBO contract with a mining company for its mine water treatment facilities. Veolia designed and built a 3,500-gpm centralized Zero Liquid Waste (ZLW) system using advanced treatment technologies.
Degassing applications in the oil industry are numerous; steam is used in nearly all processes for refining oil. Therefore, water must be treated to prevent scale and pipe pitting through the removal of dissolved ions and dissolved gasses such as oxygen and CO2. Boiler feed water for producing steam must also be free of dissolved CO2 and oxygen; SEPAREL® degassing membranes can remove both gasses in a single compact system.
During operation, a remote mine site in Nevada experienced a pit flood as a direct result of groundwater recharge where approximately 40 million gallons of water flooded the open pit and brought mine operations to a halt.
In parched California, Nestlé USA is undertaking numerous measures to conserve water in its food and beverage operations across that state. Four years into a significant drought in the nation’s most populous state, California government officials recently began initiating mandatory controls on water usage for businesses, farms, and residents. Nestlé is hoping to stay ahead of these developments and allay pressure from environmental groups that criticize increasing use of bottled water, one of the company’s major product lines.

Advanced oxidation provides an all-in-one solution that supports the complete eradication of Legionella in a water system, while also preventing its regrowth.
When it comes to answering questions about whether the oil and gas industry’s wastewater can be safely reused for other purposes, like food crops, livestock, or even drinking water, there are a number of other serious factors to be considered.
After the Supreme Court, in its 2006 Rapanos v. United States decision, admonished the U.S. EPA and Army Corps of Engineers to once and for all come up with an acceptable definition of “waters of the United States,” which is the linchpin for all regulation under the Clean Water Act, the agencies, nine years later, finalized regulations redefining that term in their 2015 Rule.
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. Part one of this series will review the importance of water samples and pilot studies as plant engineers begin to design an RO system to match their needs.
Bisphenol A (BPA) is an industrial chemical that has been used to make certain plastics and resins since the 1960s. In recent years, science has shown that exposure to BPA and its alternatives can result in possible human health effects. Adverse effects on neurodevelopment, behavior, metabolism, and the immune and cardiovascular systems have been found in human and animal models. As a result, regulators and researchers are interested in learning more about bisphenol chemicals.
Across the country, farmers face unrelenting pressure to conserve both water and energy. From California to Texas, recent droughts and declining groundwater levels require more pumping to provide irrigation water for crops. Pumping water takes energy, as do many other precision agriculture tasks involved in running a successful farm today. This symbiotic relationship between water and energy use — often called the energy-water nexus — is taking its toll on America’s agricultural industry.
Capacitive deionization (CDI), sometimes called electrochemical demineralization, is referred to as Radial Deionization (RDI) by Atlantis Technologies, which has developed a proprietary form of the process.

Onshore crude oil production has increased in the United States over the past few years. Oil producers, specifically the North Dakota Pipeline Authority and the Bakken Shale field producers are transporting crude oil by rail and train to both the East and West Coast oil refineries. While rail tends to be one of the safer and more efficient ways of transporting crude oil, there is still a risk of a spill. Oil spills are threats to both ground and surface waters, which can ultimately impact drinking water.
Jeff Garner, Senior Vice President with MWH Constructors, covers a lot of area in this Water Talk interview, which focuses on alternative project delivery models (particularly the construction manager at-risk (CMAR) approach), the water-energy-food nexus, and the thermal hydrolysis process (THP) for on-site energy generation.
Boiler feedwater is comprised of two very important, and increasingly expensive resources: steam condensate return and city (or well) makeup water. The condensate is valuable due to low electrical conductance, purity, and high temperature. The makeup water is valuable because it is being overused and under conserved in many parts of the country, making the cost of water rise in almost all parts of the U.S.
Just when we thought the jurisdictional and regulatory issues concerning the federal Clean Water Act and the resulting implications could not get more complicated, recent developments have put that possibility to rest.
