A
semipermeable membrane, is a thin layer of material capable of
separating substances when a driving force is applied across the
membrane. Once considered a viable technology only for desalination,
membrane processes are increasingly employed for removal of bacteria and
other microorganisms, particulate material, and natural organic
material, which can impart color, tastes, and odors to the water and
react with disinfectants to form disinfection byproducts (DBP).
As advancements are made in membrane
production and module design, capital and operating costs continue to
decline.
The primary advantages of low-pressure
UF membrane processes compared with conventional clarification and
disinfection (post-chlorination) processes are:
• No need for chemicals (coagulants,
flocculates, disinfectants, pH adjustment)
• Size-exclusion filtration as opposed to media depth filtration
• Good and constant quality of the treated water in terms of particle
and microbial removal
• Process and plant compactness
• Simple automation
UltraFiltration is used to remove
essentially all colloidal particles (0.01 to 1.0 microns) from water and
some of the largest dissolved contaminants. The pore size in a UF
membrane is mainly responsible for determining the type and size of
contaminants removed.
In general, membrane pores range in
size from 0.005 to 0.1 micron. UF membrane manufacturers classify each
UF product as having a specific molecular weight cutoff (MWC), which is
a rough measurement of the size of contaminants removed by a given UF
membrane.
A 100,000 MWC UF membrane means that
when water containing a given standard compound with a molecular weight
of around 100,000 daltons is fed to the UF unit, nearly all of the
compounds will not pass through the membrane.
Substances with a molecular weight of
100,000 daltons have a size of about 0.05 microns to about 0.08 microns
in diameter.
UF membranes are used where
essentially all colloidal particles (including most pathogenic
organisms) must be removed, but most of the dissolved solids may pass
through the membrane without causing problems downstream or in the
finished water. UF will remove most turbidity from water.
The water flows through the UF membrane at a rate that
is slower than with other filtration media, but rapid enough to collect
without need of a holding tank or a long period of waiting to fill a
collection vessel.

Corrected Water Systems
"The
Water You Want" ~ Pure Water Fit To Drink
We have been in the water purification business for
over 30 years.
We offer
multiple
choices for good water purification, including both "corrected" reverse
osmosis units, and advanced filtration systems, all centered around redox media
(KDF or Eagle Redox Alloy) because of its
unique properties, effectiveness and affordability.
NOTE:
Redox alloy is a relatively expensive material.
Our purifiers have the substantial amount of
redox media
needed to do a thorough job. There are other brands,
some with the same kind of housing as ours,
that contain only a small amount of redox media so they may claim to have
it. These will perform less well and for a shorter time than ours.
Our redox and carbon water filter
cartridges do a great job for one to two years depending on the volume
and type of water processed. The larger the family, or the dirtier
the water, the sooner you would change the cartridge.
Clean your water
of bad taste & odor, chlorine, volatile organic chemicals, heavy metals,
agricultural poisons, drugs,
lime and scale. Our revolutionary processes effectively clear more
household water chemicals and other water problems than other types of water
treatment.
The solid
carbon block water cartridge used in some of our systems has an extra fine
screening ability. The pure,
high-pressure solid carbon in our filter systems will remove particles
as small as a micron,
eliminating even most bacteria. The reverse osmosis units screen down to
sub-micron size for very thorough removal of chemicals and
microorganisms.
We also
have several systems that remove the toxic
fluoride added to most
cities' water supply, supposedly for dental benefits. Those wishing to
use it for their teeth can use toothpaste and mouthwash with
fluoride.
You should not be drinking this toxic chemical.
Our unique
reverse osmosis
and ultrafiltration systems have the option of including a
"Corrected
Water" cartridge
to improve water, which may otherwise be too acidic. This
remineralizing alkalizer
is also an option with our fluoride filtration systems. It can be added to most of
our systems.
Our
Corrected Water cartridges "energize" the water as well, by conditioning it
with minerals and Far Infrared energy. The resulting water is ideal for
functionality in the body. The water performs better at doing the things
that water does.
Current prices for our complete
line of quality point-of-use kitchen water purifier
systems range from $78.97 for the Single Counter Top unit to
$309.70 for a corrected under counter reverse osmosis system.
All of our drinking water purifiers have replaceable cartridges.
Single Counter Top Filter

One of our
point-of-use Redox & Carbon units or reverse osmosis
systems will
effectively reduce or remove the following contaminants:
~algae
~bacteria ~parasites ~mold/fungus ~bad taste ~bad odor
~pesticides (eg. Endrin, Lindane, Methoxychlor, Toxaphene, etc.) ~herbicides
(eg. Silvex; 2, 4-D; etc.) ~fertilizers ~nitrates

NOTE: For those on
fluoridated city water, our special units with
redox
+ "alumina" or our reverse osmosis systems will more thoroughly eliminate fluoride.
NOTE:
It is recommended you have a
Corrected Water cartridge
with either of these systems.
All
components of our water systems are free of BPA.
WARRANTY: Our
point-of-use water filtration system housings and hardware have a
warranty to be free of defects in materials and manufacture,
with repair or replacement
for up to one year from date
of purchase, and our water cartridges for up to 90 days.
