Residential drinking water treatment unit products have many standards and protocols available to companies to demonstrate that their products have been tested and certified to verify that the materials that come into contact with drinking water are not harmful, the products are structurally sound and the performance reduction claims are accurate. Commercial products were seemingly left in the dust, however, and end users do not have a significant amount of guidance within the standards to make the same distinctions about these larger systems.
Testing & certification options for commercial water treatment systems
On April 11, the U.S. Environmental Protection Agency (EPA) announced its 2014 to 2018 Strategic Plan, with goals that include protecting U.S. waters, ensuring the safety of chemicals, and protecting human health and the environment through enhanced compliance activities.
Green chemicals play a role in water treatment & reuse applications
Anyone who owns an aquarium knows how difficult it is to maintain water quality at a consistently high level. The principle “the larger the tank, the more stable the water values,” depends on the number and size of the tank’s inhabitants. When those inhabitants are dolphins, as at the Nuremberg Zoo, located in the Nuremberg Reichswald southeast of Nuremberg, Germany, the water treatment requirements are particularly challenging.

The High Output (HO) line of UV water treatment systems is designed for commercial and industrial applications. These products are intended for disinfection, ozone destruction and total organic carbon reduction, and are available in flow rates from 30 to 800 gpm. Each system is specifically engineered to provide optimized flow and retention time to effectively reduce bacteria by up to 99.9%. Dosage levels of 30,000 µw seconds per sq cm and higher at rated flow provide effective UV treatment.
The Coyote UV Series is an in-house engineered design manufactured in the U.S. and specifically intended for a wide range of commercial and industrial applications. Its modular design provides for fast turnaround times. These products are available in flow rates from 40 to 150 gpm for clear freshwater and can be used for disinfection, ozone destruction or TOC reduction.
The validated UNLV 800-W amalgam lamp provides a high dose of UV light with the lowest possible electrical connection. The lamps are up to three times more efficient than medium-pressure lamps. They can be used for agriculture, landscaping, golf courses, urinal flushing and dust suppression, as well as aquifer storage.
NSF Intl. now offers StaySafer certification, a program that ensures food and water safety, to hospitality centers around the world. Water Quality Products Editorial Assistant Chelsea Corbin recently spoke with NSF’s Sonia Acuña-Rubio and Carolyn Gillilland about the program, designed to build travelers’ confidence in the water safety and quality of their travel destinations.
Water and food safety for the hospitality industry
Axeon Water Technologies has enhanced the R1-Series reverse osmosis (RO) system offering with three new models. These systems are engineered and manufactured for commercial and light industrial applications up to 20,000 gal per day. The high-efficiency systems use Axeon ultra-low-energy membrane elements that deliver high-quality water with improved energy efficiency.
High-quality bag housings and bags are essential to maximizing the performance of a filtration system. Heavy-duty ASME Code bag housings are available in various sizes, materials and with custom features, and are designed for commercial and industrial filter applications.
StaySafer program will help the hospitality industry prevent food and water contamination
NSF Intl. launched a new program that helps hotels, resorts and other hospitality settings prevent food and water contamination. The StaySafer program provides the hospitality industry with a credible means to demonstrate the safety of its food and water to travelers, agencies and hotel rating websites.
