OPERATING PARAMETERS

To insure proper operation of your Aquathin system, it is
advisable to collect the following information about your
water supply. This information is generally available
from your municipal water department, and in many
cases is available from the website of your local
Department of Public Works.

Pressure

In order to overcome the natural osmotic force, adequate
water pressure must be available from your water supply.
The osmotic force is directly proportional to the
concentration of dissolved solids in the water. When the
water pressure is equal to the osmotic force, there will be
no movement of pure water molecules across the semi-
permeable reverse osmosis module. A minimum of 45
PSI is required. (If your water pressure is below 45 PSI, a
booster pump is available. If you are on a private well,
have your plumber raise the minimum pressure above 45
PSI.)
In general, the higher the pressure (up to 100 PSI), the
better the performance of the module at rejecting
contaminants.
pH
The Aquathin HRO TFC module will hold up very well
when the pH of the feed water is between 2 and 11.
Water supplies with pH over 11 are very rarely, if ever,
found. (Chlorine bleach has a pH of ~11.5.)

Chlorine and Chloramines

Chlorine is the most common substance added to
municipal water supplies. Its purpose is to eliminate
biological growth (i.e. chlorine is toxic). Regulations
usually require there be residual chlorine when water
