Florida officials are going back to the drawing board in the effort to create water pollution regulations for the state.
The most common technologies utilized in the treatment of natural bodies of water that become polluted, or begin to undergo eutrophication, involve primarily some form of physical or chemical treatment such as chemical oxidizers, flocculants, activated carbon and zeolites, and/or mechanical treatments such as dredging. The primary drawback to chemical treatments is that the treatments are based on stoichiometry or molecule to molecule interactions. As a result, they get very expensive when treating large volumes of water.
Malta is an archipelago of three islands situated in the Mediterranean Sea, around fifty miles south of Sicily. There are no rivers of any significance on the islands, and the sparse annual rainfall is only about 500 mm. There is a water deficit in Malta. It occurs especially in summer when there is a great demand from the farmers for their irrigation and from the tourism sector.
Water utilities are concerned that cutting federal regulations for infrastructure projects could threaten water quality.
The U.S. EPA has moved swiftly to suspend an Obama-era water regulation in the aftermath of a Supreme Court decision that boosted the odds the court-contested rule would become enforceable.
A ski resort town near Yellowstone National Park is the latest example of a growing trend in water reuse — snowmaking. Rapid population growth in Big Sky, MT is depleting groundwater, the only source of drinking water for the community. At the same time, the rise in wastewater has the town’s sewage system running at capacity. And with residents fervently opposed to discharging the treated wastewater into the Gallatin River, the Big Sky Sustainable Water Solutions Forum is evaluating snowmaking as a viable option for wastewater disposal.
Water quality standards introduced by Florida’s Department of Environmental Protection (DEP) came under renewed scrutiny late last month as Miami-Dade’s government operations committee joined a lawsuit to challenge them.
Over the past 10 years, DC Water has become the harbinger of the modern water utility. It’s often unconventional approach to tackling age-old problems usually elicits one of two responses from other utility professionals. The first response is one of resignation — if only I had the budget that size permits, I’d be able to do similar things. And the second is one of awe — there’s no way I have the amount of gumption to convince regulators or customers that I have a better way.
Over the past 10 years, both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) have issued new and revised regulations and guidances in an attempt to define, clarify, and modernize their requirements.
Weather plays an important role in how Americans think about water. And I don’t mean when it’s raining, we decide to grab a raincoat.
Smartphone and tablet cases abound. We buy sleek, beautifully executed smartphones for our personal use, then cover them up with a “protective” case. Some cases offer moderate protection, although most of them have only minimal value and are selected to differentiate your phone. We tell ourselves that we’ve protected this $700 purchase from our clumsy selves, but what we’ve mostly “protected” was the profit margin of the retailer.
In June, 2016, a new Love’s Travel Stop opened in Boardman, Oregon, offering professional truck drivers and other travelers 24-hour access to clean, safe places to buy gas, diesel fuel, travel items, meals, and snacks.

There is a lot of buzz about smart water management in the water and wastewater market these days. It seems that every manufacturer, service provider and consultant is attempting to differentiate their offering by focusing on how smart it is. But in this modern age of data-driven operations, an old adage holds true: junk in, junk out. Regardless of how good your analytics package is, if you don’t collect reliable source data, your results will be skewed.
Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.
Wastewater treatment plants process tons and tons of sludge every year and they have to contend with the question of what to do with it. Increasingly, biosolids are looked at as an opportunity to help the planet.
Total Retail surveyed its retail executive audience to understand current and future retail technology trends and buying behaviors. The results show that while innovative retail technologies such as augmented and virtual reality, chatbots (i.e., artificial intelligence), and drones get a lot of media attention for how they’re going to disrupt the industry — it’s more basic solutions like marketing automation software, video and mobile websites that currently have retailers’ attention.

About 300 convened at the two-day event, eager and ready to work together.
From Cape Town to Puerto Rico to Flint, Michigan, it's no surprise that drought, flooding and water pollution can devastate communities, impacting lives and hindering economic growth. But the physical components of water supply – its abundance or scarcity, levels of pollution, and the competition over it — are only half of the equation when it comes to overall water security. What's just as important is how water is managed by public institutions, such as water utilities and local governments.
Protecting the public health and ensuring water is safe to drink is the highest goal of water system managers. Negative health effects are indicated from exposure to per- and polyfluoroalkyl substances (PFAS), such as perfluorooctanoic acid (PFOA) and perfluorooctyl sulfonate (PFOS). Based on lab studies, the U.S. EPA has issued a health advisory for PFOA and PFOS in drinking water of 70 parts per trillion. While health advisories are not enforceable, they offer a margin of safety for consumers.

Queen’s immortal Bohemian Rhapsody asks a question that can directly apply to mathematical models: How do we know that numerical models are true? How do we know that they are defensible? More importantly, how can a modeler convey to customers the care he or she put into the model itself? Those questions are important to the water industry, where leading companies are making better use of sophisticated models every day.
Pharmaceutical water is key to the production of pharmaceutical drug products, and there have been a number of technological advancements in high-purity pharmaceutical-grade water.
Those who are philanthropically-minded need look no further for a cause than that of water. After all, this is a fundamental aspect of human existence and one that is shockingly scarce in some parts of the world.
For drinking water treatment plants (DWTPs), the EPA’s Disinfection Byproduct Rule (DBP) is a way of life. Unfortunately, for many facilities the equipment and operations haven’t evolved with the regulation mandates, leaving facilities in a tough spot. For a DWTP in Douglas County, KS, its challenges with accurate TOC measurement and testing, along with expensive calibrations and extended downtime with its prior TOC analyzer led it to trialing the Hach QbD1200 TOC Analyzer. Read the full case study to learn more.
A power plant in Egypt needed to use seawater from the nearby Red Sea as feed water for its plant processes. This case study shows how Fluence designed and built a new seawater demineralization plant that includes an ultrafiltration pretreatment, reverse osmosis, and mixed bed ion exchange.
The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless, and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.
When IT service providers become MSPs, the transition isn’t always easy. It requires a fundamental change in the way business is done. What you sell—and what you shouldn’t sell—needs to be clearly considered if success is part of your plan.
The latest phase of the project has seen ZS blowers installed at the Little Eaton Water Treatment Works in Derbyshire, which supplies safe, clean drinking water to the growing community in the city’s North-West area. Over time, it became clear that the site’s RGF process required a significant overhaul in order to improve operational efficiency, which would require the replacement of its existing blower installation.
