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.

Backwash Systems Provide Conservation and Treatment

Publication Date: 
June 18, 2012

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.

Filter Formula

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.

Extending Resin Life

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.

Performance Testing for Media & Systems

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.”

Granular Activated Carbon Not Working?

Ever since granular adsorbent media such as bone char and granular activated carbon (GAC) replaced powdered activated carbon (PAC), the amount of air in a bed of dry GAC has adversely affected the performance of many adsorption systems. Too many operators of liquid phase adsorption systems are unaware of this property.
