A computing program is necessary to draw the curves, to obtain the water characteristics with a better accuracy than can be read from the cakco. TCTerms is here for the purpose of finding answers to questions. Previous Thread Next Thread. Revue des sciences de l’eau 15, no. The variable may also be considered as practically constant in the field of natural waters. Use signifies your agreement.

The graphical method here described, in conjunction with an associated computer programme, also constitutes an excellent introduction to the more complete computing methods developed elsewhere but which could not be treated in the limited frame of this publication.

The paper shows how it is possible, on the basis of the diagram, to predict the evolution carboniue the water when different reagents are added, when the temperature changes or czrbonique one mixes different waters. Refutation of an answer should be based only on the answer or its resources.


All non-linguistic content will be removed. The paper describes how to use the graph and brings out its ease of use for both the qualitative and quantitative prediction of the behaviour of water in contact with calcium carbonate.

équilibre calco-carbonique

Edited by Rosalind Howarth on I found equilibbre examples. The diagram should be a useful aid for those people whose job is connected with industrial water treatment. The balance we care about is carbonate — its concentration and its chemical speciation carbonate vs.

LPLWin logiciel calco-carbonique Software for resolution of the calco-carbonic equilibrium The LPLWin software allows to characterize waters face to face of the calco-carbonic balance, so allowing to predict and to correct the problems of scaling, aggressiveness and corrosion of materials in contact of the water.

We would talk about the carbonate balance, or better yet, “carbonate buffering.

This is a process for on-site nuclear waste treatment but it is a promotional, not a technical document. Although many good methods exist for computing calcium-carbonate equilibria, we considered that it was still possible to improve the representation to csrbonique problem and for this reason we have developed a new method of calculation.

During the display of the curve of balance the mouse cursor allows to know the characteristics of any point of the graph and an adjustable magnifying glass allows to post details. Numerous examples for using the graph under different circumstances are developed. OK, I’ll go with “carbonate buffering. Site Map Advertise Mobile View.

The French original does imply that calcium is available as a counter-ion in this buffer system Only discussions that contribute to finding solutions and do not aggravate are permitted.


If you want to be accurate, I’d opt for “carbonate buffering” with or without the word “calcium”. Water, calcium carbonate, equilibria, graphical method, treatments, software. Cookies caco us deliver our services.

The program computes then the equilibrium pH, the stabilisation pH and the stabilisation index and draws the graphs described in the paper. Mail comments and suggestions to TranslatorsCafe.

George Leonard Trail Mother tongue: The graphical method here described, in conjunction with the associated computer programme, constitutes equilibrre an excellent introduction to the more complete computing methods developed elsewhere but which could not be treated in the limited frame of this publication.

To be sure, is “calcium carbonate balance” OK?

He allows to solve in a few seconds the equations of the calco-carbonic balance allowing to characterize waters. Dictionary and thread title search: The graph is shown to be a useful tool for the characterisation of waters as well as for the evaluation of most chemical treatments.

In every stage and on the analysis of origin, the program posts and allows the impression of 2 curves of equilibrium simultaneously and slips of analysis.
