The WaterCycle®
Rx Series
WaterCycle is predictive modeling software
for the prediction and prevention of scale and
corrosion in cooling water systems. Water treatment
professionals use WaterCycle to model scale, corrosion, and
inhibitors, and to choose, develop and optimize
treatment programs and products.
The WaterCycle series addresses the needs of
both once through and open recirculating (cooling tower)
systems.

Calculation Engine
WaterCycle is not a simple spreadsheet model.
Although it calculates simple indices for reference, French
Creek products use a much more powerful and sophisticated ion
association model.
The ion association model improves the realism and accuracy of
indices and extends the applicable ionic strength for
calculations; providing consistent, reproducible indices for
common, and not so common scale forming species.
Who Uses WaterCycle?
WaterCycle is used by water treatment
chemists, service technicians, salesman, research and
development chemists, manufacturers of polymers & inhibitors, ae
firms, equipment manaufacturers, independent consultants and
other water treatment professionals charged with cooling system
management. French Creek is proud to be part of the curriculum
at several well respected engineering schools.
Through special licensing, WaterCycle's
calculation engine is available for use in automated
controllers.
|
| Ion Association Models |
|
Though simple indices provide insight they
are limited to simple estimation methods, and do not take into
account phenomena such as "Common Ion Effects." Ion association
models are based on free ion concentration rather than total
analytical values.
Ions in water are typically associated with
other ions. Indices calculated based upon total ion
concentration can be misleading. Ion association models
overcome this by modeling the concentration of free ions rather
than total analytical values.

Premium Editions
WaterCycle Rx
Salesman Edition
The Salesman Edition performs
all of the functions and has all of the features of the basic WaterCycle
program. It adds the ability to select a water treatment product and
obtain dosage recommendations. Each table has an additional line for
Dosage or Predicted Corrosion Rate in the Rx
series, of which the Salesman Edition is the first. An additional graph
selection appears for all two (2D), three (3D), and four (4d)
dimensional graphs - the Dosage Profile.
The Salesman edition can load a
Product File (.PRD) for use in determining treatment rates and
developing dosage profiles. But, alas, the Salesman Edition lacks the
ability to edit or create Product Files, or even look at the
ingredients. They must be created (and edited) using a higher member of
the WaterCycle Rx
Series. Both the Product Manager and Laboratory
Editions can create and edit Product Files.
Salesman Editions are used extensively by field sales
and service engineers, and by plant chemists for optimizing treatment
levels.

WaterCycle Rx
Product Manager Edition
The Product Manager Edition
adds the ability to create and edit product files. Creating a Product
File is as simple as filling in a computerized formula (batch) sheet.
Product Files can be password protected to maintain confidentiality.
Files so created can be used by the Product Manager Edition or copied to
the \WATER\INHIB sub-directory on other computers with WaterCycle Rx
programs.
Product Manager Editions are used extensively by
water treatment companies who wish to use the inhibitor models supplied
by French Creek, by Corporate Chemists who wish to evaluate and compare
the treatment programs proposed for their cooling systems, and by
consultants for performing in-depth technical and economic analyses of
aqueous systems.

WaterCycle Rx
Laboratory Edition
The Laboratory Edition adds the ability to develop
scale inhibitor, corrosion inhibitor, and corrosion rate predictive
models from laboratory data, field data, or a combination of both.
Dosages (or Rates) can be modeled as a function of any parameters input
into the program in their raw form, calculated indices, and other
parameters calculated by the program.
Transforms are available and
can be applied independently to each variable. For example, a CaCO3
inhibitor might be modeled:
This is, in fact, a common model for phosphonate
inhibitors.
A simple corrosion rate model might be correlated
as follows:
-
log(Rate) = f( log(Ca),
1./RT, log(Cl), log(SO4 ), pH)
Inhibitor models developed by the Laboratory Edition
are output to the .INH files used to develop Product Files. Raw data is
stored in .COR files. Statistics are, of course, provided on each
variable as you develop a model.
Laboratory Editions are used extensively by scale
inhibitor synthesizers, and by major water treatment companies and
industrial laboratories doing inhibitor and/or corrosion research.
Five of the top six U.S. water
treatment service companies, as ranked by sales volume, use the
Laboratory Edition. It is used by all of the major inhibitor suppliers,
and by the top industry consultants. Isn't it time for you to add
WaterCycle Rx
to your technical arsenal?
