Small Business Innovation Research Grant to fund development
The Centers for Disease Control and Prevention (CDC) has posted of a solicitation for a Small Business Innovation Research (SBIR) Grant related to development of a rapid, simple and implementable poolside test method to gather separate measures for organic and inorganic combined chlorine in pool water to improve swimming pool water and associated air quality. The submission deadline for grant applications is Sept. 5.
WQA certifies AquiSense’s PearlAqua water disinfection system
AquiSense Technologies announced that the Water Quality Assn. (WQA) certified its water disinfection system, PearlAqua. The system meets the requirements of NSF/ANSI Standard 372, which accredits providing lead-free water, and NSF/ANSI Standard 61, which certifies it as safe drinking water.
PearlAqua was the first-to-market UV-C LED water disinfection system and continues as the first UV-C LED system to receive NSF/ANSI certification. These certifications confirm that the system provides clean water without the use of lead.
Ultraviolet (UV) water disinfection is an affordable, environmentally friendly technology that can help to ensure the safety of a water supply. UV light disrupts the ability of the DNA of bacteria and viruses to replicate, rendering them safe to drink. Unlike chemical disinfection, UV water disinfection products generate no harmful disinfection byproducts, nor do they affect the mineral content or alter the taste of the treated water. UV water disinfection is effective against 99.99% of bacteria and viruses, as well as Cryptosporidium and Giardia cysts, which are resistant to chlorine.
The development of a new standard will address concerns such as Legionella
NSF Intl. and ASHRAE have signed a memorandum of understanding (MOU) dedicated to protecting public health by establishing safe management practices for building water systems.
Guidelines put onus on water agencies, building managers to combat pathogens like Legionella
The Centers for Disease Control and Prevention (CDC) released new guidelines in the fight to prevent Legionnaires' disease. The publication of the toolkit is a step forward in offering practical guidelines to help building owners control Legionella bacteria once it has entered their buildings from the public water supply.
The 304 SS three-stage wall-mounted system provides particulate reduction, microbial retention and high-dose 186 mJ/sq cm ultraviolet. Its RLC monitor provides fail-safe monitoring with alarms. It is suitable for point of use applications. The system has been performance tested, evaluated and verified by the U.S. Environmental Protection Agency with live Cryptosporidium oocysts, adenovirus and the MS2 bacteriophage.
LightWise technology, featured on Viqua PRO10, PRO20 and PRO30 UV water disinfection systems, allows the controller to reduce lamp power during periods of no water flow, leading to estimated energy savings of 30%. By adjusting the power of the UV lamp, water temperature is maintained below 104˚F and the rate of sleeve fouling is consequently reduced by as much as 60%, more than doubling the amount of time between sleeve cleaning cycles.
Ozone is increasing in popularity in U.S. residential water treatment as an alternative to chlorine and potassium permanganate disinfection. The Food and Drug Administration (FDA) approved ozone for bottled water production in the 1980s, and it is now approved for food processing. The time has come for ozone to become a standard in residential water treatment as well.
Tips on explaining the benefits of ozone generators to homeowners
SmartStream, a solution for ultraviolet water disinfection applications in residential and commercial applications, provides automatic lamp dimming, which promotes energy savings, and automatic lamp identification, which ensures proper lamp energy management to maximize lamp output. The system has a small footprint, which eases installation.
Brown Brothers Winery in Milawa, Victoria, Australia, has been crafting wines since 1889, with more than 60 wines available for tasting. The third and fourth generations of the family are keeping the tradition alive and have forged a company reputation, locally and abroad, as a wine specialist and winemaking innovator.
Innovation can be found in all facets of wine production at Brown Brothers, including its water treatment. In 2009, the company replaced its existing ultraviolet (UV) disinfection system after experiencing bacteria counts of up to 100 colony-forming units.
