Operating Theory
The Mineral Mizer utilizes several modern water technologies to cost-effectively purify your tap water supply
into buffered low-mineral water for dental unit bottles, or mineral-free, autoclave-grade water.
•
Pre-Filter
- The yellow dot pre-filter contains a combination sediment & carbon block filter. Its function is
to remove suspended particles, chlorine and chemicals from the feed water, reducing the incidence of
reverse osmosis (RO) membrane clogging and chemical degradation. The pre-filter element must be
replaced every twelve months or earlier depending on the quality of the feed water.
•
Reverse Osmosis (RO) Module
- The RO module contains a semi-permeable membrane. Its function is to
divide the RO feed water into separate permeate (low mineral) and brine (high mineral) streams. This is
accomplished by applying hydraulic pressure greater than the osmotic pressure in water containing
dissolved solids, effectively allowing water molecules to pass through the membrane while rejecting most
other molecules. The productivity of the RO membrane is measured in 2 ways:
•
water efficiency – the percentage of RO feed water that is converted to permeate water.
•
rejection rate – the percentage of minerals rejected from the RO feed water.
Both of these measures are directly affected by the RO feed water pressure and temperature. The life of the
membrane is determined by measuring the decline in the membrane’s rejection rate over time. Sans this level
of measurement, the membrane should be replaced every 24 to 36 months. (This could be earlier depending
upon quality of feed water).
DI Filters
- The red dot DI filters contain two types of beads coated with ion exchange resin. One type absorbs
molecular calcium and magnesium while the other absorbs chlorides. In exchange, the resins release hydrogen
and hydroxide ions which combine to create additional water molecules. DI filters have a specific capacity to
absorb minerals so the volume of DI water produced by a 2 filter set varies based on the mineral content of
the feed water and the rejection rate of the RO membrane. The DI filters must be replaced when exhausted
(TDS ppm > 5), and at least once annually.
