Ready2 Drink Now - Questions & Answers

Q: What is the definition of “water purifier” in relationship to “water filter”?

A: Water “purification” covers a broad spectrum of contaminants ranging from particles in water (Total Suspended Solids or TSS), TOC’s, organics, hydrocarbons, trace metals, biological forms (microbes, protozoans, and viral particles), radionuclides, and other contaminants. Using the term “purification” requires defining the water stream used, the contaminants found, and the end-point criteria in terms of water quality.

Q: Does a 1-micron filter strip minerals from water?

A: Soluble, trace minerals and trace metals have “apparent size” in the range of <0.001µ, which is 3 magnitudes of order smaller than 1µ.
These soluble “ions” will not be removed using 1µ filtration. Cation Exchange is used to remove the ions. If trace metals exist as organometallic or colloidal forms, then some of these could be removed at 1µ.

Q: What is the AquaPail™ advantage over water filters?

A: AquaPail™ has broader spectrum performance and capacity per unit volume of media for removal of trace metals, organics and hydrocarbons. AquaPail™ is more effective for removal of aflotoxins, pesticides and fungicides from water. AquaPail™ is more effective for removal of trace metals cations and oxyanions and has higher adsorbent capacity per ft3 of media.

Q: What is the function of using finer media?

A: The high surface area high-porosity of the AquaPail™ media is ideal for gravity-flow water filtration applications because it translates to good flow fluidics with minimal head loss and high solids loading capacity per ft3. Reducing the media mesh size would compromise water fluidics, with little net gain in filtration rating.

Q: Why has virus removal/killing become important and necessary in the USA?

A: Here is a June 1, 2012 Wisconsin State Journal article that describes the rising problems with local water supplies:
A new Wisconsin study on viruses in drinking water could have national impact. A Wisconsin study that shows a connection between viruses in drinking water and human illness is likely to have a national impact and could eventually lead to federal rules requiring treatment
of all public water systems, according to experts, the Wisconsin State Journal reported June 1. The research, published by the journal Environmental Health Perspectives, was conducted in 14 Wisconsin communities by two microbiologists with the U.S. Department of Agriculture’s Agricultural Research Service. The 2-year study was among the first to closely link the presence of viruses in tap water to sickness in people drinking that water. At least 60 communities in Wisconsin do not treat drinking water with chlorine or ultraviolet light,
both of which kill the contaminants, said the State Department of Natural Resources (DNR). The study found the source of viruses contaminating drinking water was likely wastewater coming from leaking sanitary sewers.
The director of the DNR Bureau of Drinking Water and Groundwater said May 31 the study prompted the U.S. Environmental Protection Agency (EPA) to begin a nationwide sampling program that could result in a federal rule requiring treatment. The EPA-funded study showed that all 14 communities studied during the 2-year project had human viruses in their tap water. Of 1,204 samples, 24% were virus-positive. The higher the virus concentration, the higher the rate of illness found in each community.

During one part of the study, when norovirus was very common in one community’s tap water, the proportion of illness in children younger than 5 years old attributable to their drinking water could have been as high as 63%.
