About French Creek

WaterCycle, hyd-RO-dose, DownHole SAT, and WatSIM modeling software by French Creek.

About French Creek Software

French Creek Software writes both commercially available and private labeled modeling software for water treatment service companies, oilfield service & petroleum companies, chemical manufacturers/synthesizers, membrane manufacturers and individual water treatment personnel.

The application-specific-software released by French Creek is used daily by water treatment personnel and chemical providers world-wide, making complex physical chemistry (ion association model - see next tabs) a  highly practical and useful, everyday tool. 

The software's intuitive interface allows a chemist or field engineer to thoroughly troubleshoot an aqueous system for scale and corrosion over a wide operating range, then model any number of standard or custom treatments. Read More »

New Features

Our Approach

Traditionally, most treatment recommendations are based upon:

  • a single water analysis
  • a single temperature, and
  • a single set of operating parameters

However, industrial systems operate over wide ranges of both temperatures and other critical parameters. In many systems, significant changes can occur seasonally - even hourly.

French Creek's Visual Chemistry approach allows treatment personnel to painlessly evaluate mineral scale potential and other chemistry over the entire operating range. In a matter of minutes, French Creek modeling software users can perform an in-depth chemistry and scale evaluation. Interpretation is made simple with French Creek's thorough set of tables and 2D & 3D color coded graphs.

Inhibitor Modeling

Most traditional methods for dosage suggestion are based off of single scale, simple indices like the Langelier Saturation Index.

French Creek Premium Editions allow treatment personnel the ability to base inhibitor dosages off of multiple scaling species, with an Ion Association Model as the driving force (see next tab for ion association model).

Dosage models developed by French Creek are correlation files combining decades of field/lab data and professional expertise.

The models predict the dosage required to inhibit deposition until the treated water has passed through a system. This delay can vary from 3 to 15 seconds in a large volume system, to days in other recirculating systems.

Thermodynamic driving forces and system operating conditions are used by the models to describe the kinetics of scale formation, growth, and the impact of inhibitors upon induction time.

The end result are trustworthy dosage recommendations and limits. Read More »

Ion Association Model - Driving Force

French Creek programs are powered by an ion association model. Ion association models predict the equilibrium distribution of species for aqueous solutions - particularly well suited for cooling water, reverse osmosis, oilfield, municipal and mining applications.

The basis of this model is that ions in solutions are not all present as the free species. For example, calcium in water is not all present as free Ca.+2. Other species form which are not available as driving forces for scale formation. Examples include the soluble calcium sulfate species, hydroxide species, and bicarbonate - carbonates.

The software uses the model to perform a full speciation of water - providing the most thorough and practical scale and treatment models available.  Read more about ion association models in the Online Library »
