WHAT IS REVERSE OSMOSIS?
Osmosis is a process in nature that allows fluid of a lower concentration to pass through a
semi-permeable membrane into a fluid of a higher concentration (See Figure 1). Because of
the difference in salt concentration, pure water flows through the membrane as though a
pressure were being applied to it (Figure 2). The effective driving force is called the osmotic
pressure. As a rough guide, the osmotic pressure is equal to about 1 psi (pounds per square
inch) per 100 ppm Total Dissolved Solids (TDS). When enough pressure is applied to the
solution with a higher concentration it can then pass through the membrane into the
solution of lower concentration. (See Figure 3). This is the basis of Reverse Osmosis.
Household water pressure is used to force tap water through the semipermeable RO
membrane. The membrane only allows the purest of water molecules to pass through it
while over 98% of most salts and other impurities are rejected and automatically rinsed from
the membrane down the drain.

WHAT DOES THE SYSTEM DO?
SpectraPure’s CSP™ RO System uses household water pressure to reverse a natural physical
process called osmosis. Water, under pressure, is forced through a semipermeable membrane
where minerals and impurities are screened out and sent down the drain with waste water.
These minerals and impurities are measured as total dissolved solids (TDS).
The system connects to a house COLD water pipe for a water supply. The system includes
replaceable sediment, carbon prefilters and a membrane. The sediment prefilter removes
sand, dirt, rust particles and other particulates while the carbon prefilter takes chlorine and
organics out of the feed water. The water then passes through the RO membrane.
The CSP™ System gives you a continuous supply of sparkling clear, delicious water for
drinking, cooking, hydroponics etc. Foods will look better and taste better too. The reliability
with the CSP™ Water Treatment System is greatly improved over other systems and costly
maintenance is avoided. The system eliminates the need to buy bottled water. Instead, it puts
high quality water at your fingertips.
