ZeroWater is praising Maryland’s clean water initiatives
The state of Maryland recently passed legislation to provide more funding to improve the quality of the Chesapeake Bay, storm water pollution rates and improve wastewater treatment plants. These initiatives are all in response to deteriorating water quality, a problem that ZeroWater is helping consumers address with its advancements in water filtration.
H2Zero Backwash/Recycle Systems conserve water by storing and treating contaminated backwash water from filtration and treatment systems. Nearly all water filtration-related processes that remove target contaminants generate liquid or solid residuals that need to be subsequently managed. Increasingly stringent regulatory discharge standards and emphasis on sustainability are demanding more environmentally friendly solutions for these residuals.

ZeroWater recently was named a “filter that really works” in Good Housekeeping magazine and appeared in a special segment on The Today Show.
In 2007, the NSF Intl. Drinking Water Treatment Unit Joint Committee revised the NSF/ANSI Standard 53 protocol for pH 8.5 lead reduction based on a substantial amount of research on particulate and colloidal lead. The research conducted by the NSF task group revealed a great deal of inconsistency in the amount of particulate lead formed from batch to batch and from laboratory to laboratory due to the precipitation of this element from the solution.

Water softener resin is extremely porous, which is beneficial because it allows for more surface area to capture calcium and other metals in source water. Surprisingly, 99% of ion exchange actually happens in the interior of the bead. Resin beads, ranging in size from 16 to 50 mesh, are abused daily during the backwash process and by contaminants in the source water. Resin could last much longer in these hostile environments with a few fairly inexpensive solutions.
Cleaning options to reduce resin fouling
The most common question from customers of water treatment systems utilizing adsorbent media is, “How long will the media/system perform?” The most common answer may be a number of months or years but should be more elaborative than a mere number. The most honest answer is, “It depends on the water chemistry.”
