AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
The company's filming amine emulsion will be used in the university’s cooling water towers
The University of Michigan is partnering with the U.S. division of French water purification company Mexel to perform a 12-month demonstration using the company’s filming amine emulsion Mexel 432/0 for cooling water treatment.
Neo-Pure stainless steel filter housings provide filtration with flow rates from 7 to 4,400 gpm. Each housing is constructed in the U.S. out of sturdy 304L or 316L stainless steel for durability in commercial and industrial filtration applications. These housings are available in standard poly-coat finish, electro-polished, or with 3M epoxy coating. ASME "U" code designs and high-pressure housings up to 600 psi are also available.
New L1-Series light commercial RO systems are ideal for a wide range of applications, including food and beverage preparation, aquariums, hydroponics, misting and more. The 200- to 300-gpd systems feature a new single-pump design, extra-low-energy membranes with auto flush, pre- and post-filtration, and a compact wall-mount space-saving design that is simple to install. They also are energy efficient.
New 2.5-in. HF5-Series ultra-low-energy membranes feature a low nominal operating pressure of 80 psi. The membranes can produce up to 2,500 gpd with 98.5% salt rejection for improved system performance. They are ideal for use in applications with cold feedwater temperatures, or where there is a decrease in required operating pressure. Quality tested to ensure they meet the high standards, the membranes also are manufactured in the U.S.
Water scarcity is a universal and growing issue. With huge projected population growth, this problem will only continue to increase. The World Economic Forum reported that the world’s population surpassed 7 billion in 2011, and is expected to reach 9.3 billion by 2050. Urbanization, industrialization, pollution, increased energy needs and climate change all reinforce the stress of population growth, making water accessibility an even more pressing issue.
Reused water keeps hotel guests cool in Dubai
Leading the national tourism average with double-digit growth in occupancy rates, the summer of 2014 was a particularly good one for hotels in the San Francisco Bay Area. The increase in demand for visitor accommodations came in the midst of an unprecedented drought in California — the worst in decades, with three drier-than-average years so far — and approval of the first statewide rules to punish water wasters. In a unanimous vote earlier this year, the California State Water Resources Control Board approved new restrictions on outdoor water use.

This article will review the benefits and challenges of implementing water reuse strategies, focused on building heating, ventilation and air conditioning (HVAC) and plumbing systems at the new 217,000-sq-ft Milton Union K-12 School. Public policy changes (codes, etc.) needed to be addressed during a project to more readily integrate these strategies into the building design. A summary of the water savings associated with incorporating these strategies is described herein.
K-12 school uses rainwater for toilet flushing & irrigation
Commercial applications for harvested rainwater are no longer a rarity in the U.S., though few uses of this heaven-sent water match the AdvancED facility in Alpharetta, Ga., for sustainability and energy efficiency. The U.S. Green Building Council thought so, too — the new global headquarters facility earned LEED Gold status.
Building leverages rainwater for HVAC energy savings
With the global population estimated to grow from 7 billion in 2011 to more than 9.5 billion by 2050, profound stress has been placed on the world’s limited water supply, not only by its burgeoning population, but also by other factors, such as rapid urbanization, industrialization, pollution and climate change.1 As water scarcity and “water stress” persist, the water treatment industry has been tasked with developing innovative solutions to produce clean, potable water.
