It’s a lazy Saturday morning at the Unger house. Mom is at work, and she left me and the kids (ages 11, nine, seven and five) a giant list of chores to complete while she is away. The problem is, we do not have much enthusiasm or energy to get them done — so what do we do?
Understanding the science behind heavy metal filtration certification
Six 3M, Aqua-Pure and Water Factory Systems products certified under new standards
3M Purification is the first to achieve Water Quality Assn. (WQA) Sustainability Certifications under the new WQA Product Sustainability standards. The products include water filtration products for the home and water appliances. 3M Purification joined a task force of other leading industry manufacturers and suppliers to assist the WQA in developing a new suite of sustainability standards for drinking water treatment products.
The water treatment industry is constantly driven to find more sustainable solutions to treatment problems. Cation exchange water softeners are extremely effective at removing hardness, but are under attack in several states due to the salt and water they discharge during regeneration. Reverse osmosis systems are effective at removing total dissolved solids (TDS), but a significant percentage of the influent water is discharged to the drain as wastewater.
Electrochemical systems offer efficient alternative
The Middle East and North Africa (MENA) region of the globe ranks among the lowest worldwide in terms of availability of renewable freshwater resources per capita. Protecting the limited supply of this vital resource is critical to public health, the environment and the economies of countries in this region. This article will explore the regulatory requirements for Abu Dhabi in the United Arab Emirates, as well as the adoption and recognition of NSF/ANSI Standard 61 in other markets.
Leading the Way
Adoption of standards in Abu Dhabi & around the world
Aquionics’ line of pool and spa disinfection systems receives NSF/ ANSI Standard 50-2012 certification
Aquionics’ UVSwim I line of pool and spa disinfection systems has become the first complete UV system range to achieve the new NSF/ ANSI Standard 50-2012 certification. The certification applies to all seven models of UVSwim I from 100+ to 4500+.
A company is only as good as the foundation it is built upon. In the Water Quality Assn.’s (WQA) case, the foundation of the organization is quite literally its laboratories. The Performance Lab, constructed in the basement of WQA’s Lisle, Ill., headquarters, conducts the first half of the testing of a unit seeking WQA certification. The Analytical Lab, also at the Lisle location, allows WQA to test samples on site in real time, providing the capability to see how a unit performs as it is running.
Onsite labs cover range of testing & certification needs
Product meets NSF compliance standards, indicating testing & analysis
SNO glacier water from Iceland has earned third-party certification from NSF Intl.
The water received NSF's certification, indicating it has met NSF's compliance standards, assuring consumers that this product has undergone extensive product testing and analysis, including a complete evaluation of every aspect of its development.
As concern for the environment moves ever closer to the forefront of public and media attention, the water treatment industry has been subjected to criticism. Reverse osmosis (RO) systems and softeners have been accused of wasting water and contributing to salinity problems, and producers of bottled water vie with filter manufacturers over which option is greener.
New standards provide sustainability certification for carbon products
Certification may seem complicated, but once it is broken down into digestible pieces, it becomes simple. There are many drinking water treatment unit (DWTU) standards, each focusing on a specific technology. NSF/ANSI Standard 42, the focus of this discussion, provides protocols and requirements for water filter certification.
Individual component certifications can be useful when certifying systems
California state legislators address the state's drinking water
A number of California state legislators included the bill for third-party certification as part of a package designed to provide clean drinking water.
Nine bills were highlighted by the lawmakers, all of them part of a program to address the state's drinking water crisis.
