INRS – SCALESWEEPER PRODUCT PERFORMANCE TEST DATA 3

BACKGROUND

The Scalesweeper product is an electro-magnetic device tested by The Institut National de la Recherche Scien-

tiﬁque (INRS) in Quebec Canada. The INRS is an independent research-oriented branch of the ten provincially

run public universities in Quebec, Canada. INRS conducts research in these sectors: water, earth and the envi-

ronment.

Professor Patrick Drogui (Ph.D) led the team verifying the performance of the Scalesweeper product. Dr. Drogui

is a well-respected expert in the areas of Electro-Technologies and Water Treatment and is credited with pub-

lishing over 120 papers and books. His research interests focus on the troubleshooting and development of new

technologies for the elimination of pollutants (inorganic and organic). Among these techniques are electro- tech-

nology processes, taking advantage of electrochemical properties and techniques in water treatment. These

techniques can be used effectively to improve existing municipal and industrial wastewater treatment systems or

to replace conventional inefﬁcient technologies for the removal of speciﬁc inorganic or organic contaminants.

TEST PROCEDURE

The test protocol was designed to verify in a laboratory pilot scale, the effectiveness of the Scalesweeper prod-

uct against forming scale build up in piping and appliances using various hard water solutions made up of cal-

cium and magnesium under the effect of electromagnetic ﬁelds. The tests were divided into two sections using

a closed loop test stand (see Figure 1 in Appendix section) with the holding tank ﬁlled with one or the other total

hardness test solutions (Very Hard, 400 ppm, 23.36 gpg)

i. Experimental Unit – will show the effectiveness of scale build up to the piping and total water hardness

measurements with and without the Scalesweeper product active in the circuit at a water temperature of

70°C (158°F) and at ﬂow rates between 3 and 7 gpm.

ii. Analytical Methods – will show the characterization of carbonate deposits using a scanning electron

microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) machine coupled with X-ray diffraction

(XRD) to quantify the percentage of each allotropic forms of calcium carbonate present.

TEST RESULTS

Experimental testing has proven that calcium and magnesium content in a water solution which are the two ma-

jor causes of scale build up in pipes and appliances CONTINUES to stay in solution form as shown in Graph 1:

Total Hardness when the Scalesweeper is TURNED ON. If the water hardness stays constant, then the calcium

and magnesium minerals are not sticking to the inside of your pipes or appliances.

Experimental testing has again proven in a different test that calcium and magnesium scale build up on your

pipes and appliances will reduce over time if the Scalesweeper is installed. Graph 2: Total Hardness shows

scale build up on a clean pipe over a 24-hour time period (0-24 hours) then shows total hardness increasing

once the Scalesweeper is TURNED ON (24-48 hours). The increase in Total Hardness is because the calcium

and magnesium scale build up is being removed from the pipe thus cleaning the inside of your pipes and appli-

ances. Once the scale changes back to aqueous solution, these minerals simply pass through your pipes and

appliance without causing additional scale build up.

Analytical Method has proven that with Scalesweeper installed on your main water pipe under SEM review that

the makeup of calcium carbonate in aragonite form is much smaller due to the electro-technology incorporated

in the Scalesweeper product and the calcium carbonate in calcite form is much larger. Thus, the calcium car-

bonate in calcite form has a much lower scale forming tendency.
