A wide range of technologies, some new and some more traditional, is being marketed and applied for arsenic treatment. Each of these technologies has specific properties impacting its suitability for any particular scale of application. While rare, the ability of a single water treatment technology to perform effectively across many treatment platforms is not unique.
Cross-platform viability of treatment technologies
In February, NSF International arranged for many experts to cover the issues and facets of point-of-use and point-of-entry (POU/POE), how they can be used for PWS compliance and other opportunities for the manufacturers and users. This article is intended to provide opinions and a broad conference overview.
Some really important research going on right now, which is critical for the point-of-use/point-of-entry (POU/POE) industry in order for POU/POE treatment to become an accepted practice for small public water system compliance. It seems as though we are closer than ever to finding acceptance in this arena.
Point-of-use (POU) water purification has a solid future. The relatively new POU industry will have to shoulder tremendous responsibility. Serious issues of water quality as well as quantity are apparent. The right of every human to water must be proactively protected if an acceptable quality of life for future generations is to be reasonably assured. This will not happen until it becomes a high priority political issue.
Industry professionals are responsible for bringing greater awareness of water quality to government officials and the public
Most reverse osmosis systems waste as much as 20 gallons just to produce one gallon of product water. The new technology called "ZeroWaste" eliminates this problem by returning the concentrate water from the reverse osmosis system back to the home's plumbing, resulting in 100 percent efficiency.
As the residential point-of-use (POU) reverse osmosis (RO) industry approaches its 35th anniversary, it is time for a reality check on the industry's progress to date as well as a look ahead to new technologies or improvements that the industry may introduce for POU RO systems in 2003.
Looking for Answers in 2003 and Beyond
Chlorine dioxide is not a new technology for public drinking water facilities or pulp and paper producers, but its use as a secondary treatment system for small-scale applications is new. Beyond the chemistry and microbiology, potential small-scale operators want answers to a few simple questions: Should I use it? How does it work? What extra work is it going to make for me?
Faucets for point-of-use (POU) water treatment systems must combine an attractive, contemporary appearance with materials that ensure safety and purity. POU faucets and systems are becoming increasingly important to help meet consumer demands for safe, high-quality drinking water. It is estimated that by 2020 almost every household will have a POU or point-of-entry (POE) water treatment system.
While both sides of the bottled/tap battle continue trying to inform and ultimately win the consumer over, a few facts cannot be overlooked. Regardless of how a consumer obtains drinking water, both bottled and tap must draw from the same available global freshwater sources. Despite the information with which consumers are presented, ultimately the decision is theirs. When purchasing bottled water, knowing what you are getting requires some research and understanding.
