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:

98.5% = [(550-8.25)/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).

DT-Series reverse osmosis systems are designed to reject up to 98.5% NaCl, unless

computer projections have been provided or stated otherwise.

The amount of permeate water recovered for use is expressed as a percentage. To

calculate % recovery, use the following formula:

% Recovery = (Product Water Flow Rate / Feed Water Flow Rate) x 100

Example:

46% = (6.94/15) x 100

NOTE: ALL FLOW RATES MUST BE EXPRESSED IN THE SAME UNITS,

TYPICALLY GALLONS PER MINUTE (GPM).

SYSTEM REQUIREMENTS AND OPERATION GUIDELINES

PLUMBING

The membranes and high pressure pumps used on DT-Series systems require a

continuous flow of water with a minimum feed pressure of 45 psi, not to exceed 85°F.

FEED WATER CONNECTION

1. Locate the 2” FNPT feed water inlet on the 18” FSI bag filter housing.

(Figure 1A, Page 15)

2. Attach the inlet piping to the 2” FNPT feed water inlet.
