Input Water Chemistry
Entering a water analysis is quick and simple. Select
whatever analytical units you prefer (or whatever your lab
or client prefers) and get modeling within minutes.
Analytical units are available for almost any reporting
method in use. Users have a wide selection of analytical unit options:
- As the Ion
- As CaCO3
- French or German Degrees of
Hardness
- EPM (equivalents per million)
- moles/L
Alkalinity units can be specified as “M” and “P”
alkalinity (as CaCO3), corrected or uncorrected HCO3 and CO3
in mg/l as
the ion, or as milliliters of N/30 sulfuric acid. “M” and
“P” alkalinity input are the default.
Incomplete Analysis
Users can select the ions to use to balance
incomplete water analyses:
Cations - Sodium or Potassium
Anions - Chloride, Sulfate or Nitrate
Carbonate Equilibrium
The software deals with the carbonate equilibrium in two
basic ways as it cycles a water:
Conservation of Alkalinity or Conservation of Total Molar
Carbon.
Carbonate based Alkalinity is conserved in systems open
to the atmosphere due to the free exchange of carbon dioxide
(CO2) with the atmosphere. Molar carbon is conserved in
totally closed, air tight systems. For most systems,
carbonate calculations should be based upon the conservation
of alkalinity.
Select Parameters
Because each product line of French Creek modeling
software is application specific, users are able to enter
and model specifically their operating parameters or a range
of parameters to model.
Depending on their application, a user can model scale potential versus a
range of temperature, pH, pressure, COC, recovery or other concentration.

View Scale Potential
Traditional scale prediction methods are for one-point, often
in worst case scenarios. French Creek modeling software
enables treatment personnel to perform mineral scale potential
evaluations for 20+ scale forming species, over an entire
operating range, in typical and stressed conditions.
The software uses
an ion association model for calculations (see
Online Library). The model and interface give treatment
personnel a practical method for simultaneously predicting
scale potential in a reproducible, transportable, and
easily sharable medium.

Visual Chemistry™ SM
French Creek modeling software utilizes a Visual Chemistry™
approach, with a variety of in-depth tables, summaries and outstanding color-coded visual aids.
Users can select exactly the operating range or range of
parameters to view, then evaluate the chemistry with
thorough
tables,
one-page reports and
2D &
3D color coded graphs.
