FEED WATER AND 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 TDS AND/OR LOWER FEED WATER TEMPERATURES WILL REDUCE THE

SYSTEM’S PRODUCTION.

REJECTION, RECOVERY AND FLOW RATES

R2-Series Reverse Osmosis Systems are designed to produce permeate water at the capacities

indicated in the “design basis section” on page 19 of this manual. For example, the R2-6140 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 98.5% rejection rate means that 98.5% 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:

99.2% = [(10,000-80)/10,000] x 100

NOTE: ALL TDS FIGURES MUST BE EXPRESSED IN THE SAME UNITS, TYPICALLY

PARTS PER MILLION (PPM) OR MILLIGRAMS PER LITER (MG/L).

R2-Series Reverse Osmosis Systems are designed to reject up to 99.2% NaCl, unless computer

projections have been provided or stated otherwise.
