PERFORMANCE AND TECHNICAL INFORMATION / 17

Measuring Temperature

Use a thermometer to measure the temperature of the

product water. It is most convenient to take this reading

when the product water flow rate is checked.

Checking System Performance

Procedure

The following procedure is summarized on the Performance

Worksheet printed on page 19. It details the measurement

and evaluation of the key aspects of Aqua-Cleer

/Good Water

system performance:

• Quality of water produced

• Quantity of water produced and stored

• Efficiency of operation

This procedure should be used to evaluate and record the

performance of a new system and to check the performance

of an operational system. The results of the new system

performance evaluation should be retained as a benchmark

of system performance in the years to come.

Checking Quality

Measure and record the TDS level of both the product water

and the feed water. Calculate the percent removal of TDS as

follows:

Removal = x 100%

As an example, consider a system which is producing 50

mg/L product water from a 1000 mg/L source:

[(1000 - 50) ÷ 1000] x 100% = 95% Removal

Checking Quantity Produced

Measure and record both the flow rate and temperature of the

product water. Record the temperature correction factor from

• Rinse the cell cup twice with water to be tested, then

fill to the top.

• Press the button on the front of the meter and read the

dial for the dissolved solids content of the product

water in parts per million (ppm).

Measuring Flow Rates

To measure flow rates, it is necessary to use a graduated

cylinder (100 ml suggested), and a watch or stopwatch with a

second hand. Measure and record the product and concen-

trate flow rates as follows:

• Collect the water sample directly from the manifold

for exactly one minute or exactly two minutes.

• Convert the measured flow rate to gallons per day (gpd)

as follows:

one minute sample: ml

two minute sample: ml

min.

2 min.

x 0.40 conversion = gpd

÷ 5 conversion = gpd
