The global need for point-of-use (POU) drinking water treatment products with microbiological reduction or purification claims has grown in recent years. The proliferation of these products is evident in developing countries such as Brazil, China, India and Mexico, where water quality is of concern to the general population.
Because microbial reduction or purification is a significant health claim, the efficacy of these products’ performance is paramount for consumer protection.
POU systems meet global standards for microbial reduction
According to statistics published by the U.S. Environmental Protection Agency (EPA), water coolers across the U.S. consume about 6 billion kWh of electricity per year.1 Some water coolers actually use more energy than a refrigerator.
Lowering energy costs with efficient water coolers
One of the largest and most well-respected teaching hospitals in Illinois is also home to a central power plant with 7,000 tons of cooling tower capacity and a 100,000-gal central chilled water loop. When newly issued corporate responsibility guidelines encouraged sustainability and green practices at its facilities, the hospital sought expertise to streamline its efforts.

Over the years, the public has become more aware of drinking water quality issues. Urban development has placed increased stress on water resources, which in turn has increased the need for cost-effective methods to treat drinking water. This is true regardless of whether the installation is at a single point of use (POU) or at the point of entry (POE) for treating all water used in the home.
Choosing the right treatment option for the water supply
More than ever, sustainable surface and groundwater supplies are essential to communities across North America and around the world. The strains of industry and agriculture on groundwater are noticeable as pressures on water supplies intensify and supply patterns change. The increase in agriculture over vulnerable aquifers, climate change and hydrocarbon production are impacting water quality. Unregulated use or uncontrolled flow of groundwater can cause water quality degradation and conflict between water users.
Small drinking water systems opt for POE UV treatment
The Iron Kit POE iron removal system features a flow-directing connection manifold coupled to an air release and filter tank in series, incorporating the R-Valve rotating head. The manifold includes air inlet, unfiltered water sample and filtered-water sample ports. It also integrates an electronic turbine flowmeter and monitor with visual and audible service alarm.
Activated carbon is commonly used in point-of-use (POU) and point-of-entry (POE) water applications. Activated carbon is predominantly used to remove organic-based contaminants and inorganic contaminants like free chlorine and monochloramine from water. Other water treatment processes such as reverse osmosis or ion exchange are better suited for other inorganic chemicals that may be present in water.
Factors impacting contaminant removal
India is regarded as one of the fastest growing global markets. With an official Indian government growth forecast of 8.75% in 2011, the country emerged relatively unscathed from the recent global economic downturn.
India occupies only 2.4% of the world’s landmass, but it has more than 15% of the world’s population, with a median age of 25. Approximately 70% of India’s population lives in more than 550,000 villages; the rest of the population lives in more than 200 towns and cities.
New filter provides low-pressure solution
There are several factors that impact the performance of a residential point-of-use (POU) reverse osmosis (RO) system. The previous article in this series (“Factors that Impact RO Filter Performance,” March 2010) highlighted how changes in the feedwater quality can impact the quality of the permeate water. This article focuses on how changes in the components used in a residential POU RO system impact the permeate water.

When bottled water sales boomed in the mid-1990s, food service and hospitality operators and distributors learned that leasing point-of-use (POU) water vending products that offered fresh cold water and hot water-based beverages could be very profitable.
Treating Vending Water
There are two common types of water cooler vending systems: mains-fed from the tap and bottled water coolers. In any environment, it is important to know how to select the right type of filtration.
