FEED WATER & OPERATION SPECIFICATIONS
Nothing has a greater effect on a reverse osmosis system than the feed water quality.
NOTE: IT IS VERY IMPORTANT TO MEET THE MINIMUM FEED WATER REQUIREMENTS.
FAILURE
TO DO SO WILL CAUSE THE MEMBRANES TO FOUL AND VOID THE
MANUFACTURER’S WARRANTY.
NOTE: HIGHER FEED TDS AND/OR LOWER TEMPERATURES WILL REDUCE THE SYSTEM’S
PRODUCTION.
REJECTION, RECOVERY AND FLOW RATES
R1-Series reverse osmosis systems are designed to produce permeate water at the capacities indicated
in the “design basis section” on page 21 of this manual. For example, the R1-6140 produces 6.25 gallons
per minute of permeate water at the listed operating test conditions.
The amount of total dissolved solids (TDS) rejected by the membrane is expressed as a percentage. For
example, a 99% rejection rate means that 99% of total dissolved solids do not pass through the
membrane. To calculate the % rejection, use the following formula:
% Rejection = [(Feed TDS – Product TDS) / Feed TDS] x 100
Example:
99% = [(550-5.5)/550] x 100
NOTE: ALL TDS FIGURES MUST BE EXPRESSED IN THE SAME UNITS, TYPICALLY PARTS PER
MILLION (PPM) OR MILLIGRAMS PER LITER (MG/L).
R1-Series reverse osmosis systems are designed to reject up to 99% NaCl, unless computer projections
have been provided or stated otherwise.
