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.
Configurable RO housing optimizes membrane serviceability and footprint
Evoqua Water Technologies introduced its new Vantage M41 reverse osmosis (RO) system for industrial applications to Asia.
The system is suitable for the production of process ingredient water, rinse water, food ingredient water, safe drinking water, boiler feedwater, ion exchange pretreatment, RO reject reclaim, wastewater recycling and many more uses. The compact skid system requires a footprint of 32.5 by 32 in. and has a height of 72.7 in., which allows it to fit through most standard doorways.
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.

Filtering water in the washing machine reduces water consumption by 30%
Through a joint development with Dow Water & Process Solutions (DW&PS), Haier Group has commercialized the first Casarte eco-friendly washing machine using Dow ultrafiltration (UF) technology. The washing machine is designed and built with the new Dow Purinze UF module, which facilitates more than 30% reduction in water consumption while improving water quality by removing as much as 99 percent of common bacteria.
Reverse osmosis (RO) is becoming a common method for treating residential drinking water. While many consumers know RO best for its use in desalination, it is also effective for treating water quality problems in the home.
RO technology helps treat & conserve swimming pool water
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.
Demand for Desalination

Dow Filmtec Eco RO elements help maintain reliable energy for major brewing company
Breweries need power to produce their products, and power plants need consistent, high-quality water to operate effectively. Because source water varies based on location, water chemistry and time of year, a power station for a major brewer in North America turned to Dow Water & Process Solutions and Consolidated Water Solutions to deliver a means to a flavorful, robust and satisfying end.
Filmtec 500-gpd residential RO elements facilitate the production of high-quality potable water. These elements use a new membrane chemistry that maximizes performance through balanced flow and high rejection, all in a compact, space-saving design that allows for consistent, quick refill with no intermediary tank. The new membrane chemistry helps utilize water more efficiently, leading to increased system recovery.
