California may have a reputation for persistent drought and water scarcity, but already this year the state’s freshwater reserves are worth celebrating.
Thanks to a high-throughput production facility in Oregon, the technology manufacturer Intel is the area’s largest water consumer by far. Now, the state will help it pay for a massive water treatment project that will help it recycle some of that water.
Phosphorus is an essential element for organisms and plants. In natural, uncontaminated waters, it occurs as organically bound phosphate, condensed phosphates or as orthophosphate — often referred to by its chemical formula PO4-P. The small quantity of phosphorus present in natural waters does not promote the growth of plants. However, a rise in the concentration of phosphorus results in the proliferation of algae, which leads to the eutrophication of the water body.
For some water providers, carefree days of producing pure, fresh water from groundwater sources are long gone. Years of evolving chemical complexity, industrial operations, and short-sighted disposal methods have taken a toll on groundwater sources. The lowering of maximum contaminant levels (MCL) for contaminants such as chromium and the drilling of new wells into different geologic structures add to source water pressures. Fortunately, new technologies are helping water providers make the best of a challenging situation across a wide range of contaminants.
With backing from two of the biggest tech entrepreneurs in American history, a new solar-powered solution to water scarcity has raised a massive amount of money.
The latest solution for national water scarcity may seem like a major technical challenge, but with a nine-figure investment and federal backing, it could be a gamechanger.
Propeller flow meters have long been an important tool for agricultural irrigation management. As water scarcity and resource management have become increasingly critical, getting the most timely, accurate readings available from those meters is becoming more important than ever. Here is how growers and water conservation districts (WCDs) are each getting the best of both worlds for their own purposes.
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.
On December 11th, the U.S. Environmental Protection Agency (EPA) and the Department of the Army (Army) proposed a new definition of “Waters of the United States” to replace the 2015 definition adopted under the Obama administration. That definition has been subject to a variety of litigation over the past three years, causing its application to be sporadic at best.
Las Vegas water planners are prepping for a harrowing possibility: The disappearance of the Colorado River.
The first blood tests results were released since water contamination in the Philadelphia suburbs came to light, and they provide a glimpse at potential health effects for residents.
In the Louisiana community of Enterprise, tap water is so unappealing that one woman drives 20 miles each way to do her laundry in another town, according to CNN.
Water is becoming more complex for industry. Its cost as a component of production is on the rise, and greater regulatory scrutiny continues to expand post-process wastewater treatment. Against a backdrop of growing water scarcity, industrial leaders are focusing more time and energy into leveraging water acquisition and usage to their competitive advantage. The days when access to water was taken for granted are over. In fact, by 2030 global water demand is projected to exceed available water by 40 percent.
A city near Phoenix recently greenlit a major indirect potable reuse project designed to support the water supply in an area threatened by drought, rising demand, and climate change.
Access to clean, safe, fresh water is one of the greatest challenges facing humanity in the 21st century. By some estimates over 1.5 billion people face water scarcity issues that directly threaten their health or economic welfare on a daily basis. More concerning, the impacts of climate change and global population growth are expected to exacerbate these issues to impact over 2.3 billion people by the year 2050. These sobering facts are why six of the United Nations (UN) Sustainable Development Goals (SDGs) are focused on providing access to clean, safe water. Part of solving this challenge is reducing industrial water consumption to conserve water resources.
Water utilities rely on accurate and dependable flow measurement for critical process controls. Regulatory agencies also require flow monitoring and reporting, with specific accuracy limits.
Potable reuse of wastewater has gone by many different names, some of them unflattering, like “toilet to tap.” Despite the clear benefits of water reuse, this so-called “ick factor” has slowed the adoption of technology that can transform wastewater into drinking water.
Beyond the existential philosophy implications, the consequences of a pipeline leaking in a forest when no one is around highlight the desirability of leak detection systems in water distribution utilities as a whole. As the following experiences show, leak detection can have its entertaining side. On the other side of the coin, however, the consequences of not monitoring leaks can also trigger a tsunami of costs far beyond the expense of pipeline repair alone.
Enhanced biological phosphorus removal (EBPR) was first documented in the early 1970’s. Traditionally it has been understood that EBPR requires a first stage anaerobic zone that is free of nitrate and nitrite. In the anaerobic zone, phosphorus accumulating organisms (PAO) utilize energy from stored polyphosphate to assimilate volatile fatty acids (VFAs) and produce polyhydroxybutyrate storage products.
Over the past decade, there has been a considerable effort in the water sector to address industry shortcomings through collaboration. And perhaps there’s been no greater initiative to try to help water utility managers in their day-to-day and future planning than the Effective Utility Management (EUM) Initiative.
Here are the top three trends happening in retail this year and our predictions for what’s going to be big next year.
Industrial companies need reliable water treatment technology, since failure of a water system may result in downtime for production, with significant financial impacts. Ultraviolet (UV) technology is used for water treatment in various industries such as microelectronics, food & beverage, pharmaceuticals, and many other industry segments.
Similar to other deskless industries, there are unique employee engagement challenges facing the utilities industry brought on by advances in technology and a shortage of qualified workers. The latest employee engagement statistics reveal that only 52% of utility workers are engaged. With many changes happening in the industry and an often stressful and even dangerous work environment, it’s no surprise that employee engagement is a challenge.
“How can a coastal city that is flanked by an almost endless bank of water have water scarcity problems?”
The Ganges is a lifeline for millions of people who live within its catchment as a source of water, transport, and food. During the Hindu pilgrimage known as Kumbh Mela, the Ganges plays host to the largest human gathering on Earth as 120 million people arrive to bathe in the river over 49 days.
Keeping an eye on what happens with domestic oil and gas regulation is a bit like herding cats. We’ve seen encouraging progress on air quality issues related to oil and gas, but an equally critical front that’s seen major action is protection of our land and water resources.
Rio de Janeiro boasts the world's largest water treatment plant, and it's working overtime. The Guandu Water Treatment Station provides 90 percent of the city of Rio's water, and it's increasingly grappling with water quality problems. One challenge is that forest loss and landscape degradation upstream of the city is causing soil erosion, which generates more pollution, and fills reservoirs with sediment instead of water.
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.
In the beverage industry, there are many opportunities for degassing with a SEPAREL® hollow fiber membrane due to the fact that water treatment is not as elaborate as other industries. The main focuses of water treatment in the beverage industry are the removal of harmful bacteria and dissolved chemicals for health reasons as well as the conservation of water’s natural flavor by eliminating dissolved ions, particles, and chlorine.
Most treatment systems for removing iron and manganese from groundwater sources use chlorine, oxygen or various other chemicals to oxidize the clear state of iron and manganese to an oxidized or solid form so the particles can then be filtered out. If complete oxidation occurs and if the oxidized floc is of suitable condition, a filtration system consisting of filter sand and anthracite is used.
This article is intended to highlight inconsistencies in testing elastomer vial stoppers — and to drive the collaborative development of a more sensitive, harmonized particle count method.
Wastewater service charges vary considerably across EPA regions and States. That’s one of the key findings from the National Association of Clean Water Agencies’ (NACWA) Cost of Clean Water Index. If you live in Montana, Wyoming or the Dakotas (EPA Region 8), your average service charge of $261 a year is considerably less than the $884 your fellow Americans up in New England (EPA Region 1) are paying. As you can imagine, much of the difference is to do with population size and geography.
The Mountain Regional Water District is a Special Service District of the county that was established by the Summit County Commission in 2000 to regionalize water service by consolidating several public and private water companies.
Refineries are among the major consumers of water that has both process and non-process origins. The average refinery requires 2.5 gallons of water for every gallon of crude oil processed. Depending on the type of crude oil, composition of condensate and treatment processes, the characteristics of refinery wastewater varies widely. The design and operation of modern refinery wastewater treatment plants are challenging and are driven by technology. This article will highlight the most common types of waste streams in a refinery and suitable wastewater treatment strategies.
