In communities around the world, water supply encounters elevated pressure from population expansion, climate seasonality, pollution and geographical changes that affect water storage in both volume and quality. As communities work proactively towards sustainable water conservation and seek alternative sources of water, water reuse or “reclaimed” water, provides a beneficial source for drinking, irrigation, and industrial applications, supporting expansion of water reserves through new treatment mechanisms.

In recent years, UV Pure® has spent time educating and familiarizing its team on countries that from suffer water scarcity, starting with Australia, Spain, Italy, and Mexico. Nevertheless, in the United States we find equal source shortages in states such as California, Texas, and Florida. In our mission to provide safe water, there are various things to consider, including geographical challenges. In areas commonly impacted by drought, it is important to consider water supply when balancing increasing population growth and heavy industrial and agricultural demand.

Leading UV technologies enhance water reuse

As societal challenges lead water treatment technologies through new routes, ultraviolet disinfection (UV) has expanded its incision within wastewater reuse, presently considered a key element to wastewater treatment. When a chemical disinfection approach comes to application, reuse water will require further steps of processing through chlorination, dechlorination, and aeration. In wastewater applications, high chlorine doses are frequently required, further increasing the likelihood of by-product formation. In contrast to chemical disinfection, UV disinfection not only eliminates the possibility of existing by-products through chemical treatment, it also eliminates the three-step disinfection process described.

Currently considered a mainstream technology for reuse water disinfection, the efficacy of UV disinfection for reuse application is directly correlated with high dose requirements. In North America, the Ultraviolet Disinfection Guidelines for Drinking Water and Water Reuse, published by the National Water Research Institute (NWRI) / American Water Works Association (AWWA), establishes safety standards that promote efficiency in disinfection. In California, dose requirements for water reuse are based as of Title 22 regulations.

Sustainability through Hallett™ Reuse product line

As UV Pure seeks to ensure water quality and sustainability in all spectrums of applications, our group has launched the Hallett™ Reuse product line, unlocking the potential of our patented Crossfire™ technology for water reuse and rainwater harvesting. With the Hallett 500R (H500R), H750R and H1000R, UV Pure Technologies is fully committed to safely addressing requirements relevant to water conservation and reuse programs through regulated standards such as U.S. Environmental Protection Agency (US EPA) UV Disinfection Guidance Manual (UVDGM) and NWRI.
