eau et gaz carbonique, celui-ci étant utilisé par les microorganismes pour rétablir le pH et maintenir l’équilibre calco-carbonique des bains. Nouveau mode de représentation graphique de l’équilibre calco-carbonique Application au traitement des eaux. An article from journal Revue des sciences de. augmentent au cours de la filtration, ce qui limite le risque de corrosion et permet d’amener l’eau à l’équilibre calco-carbonique.

When I google “carbonate balance” I usually end up with “calcium carbonate balance. Comments Merci a tous! Any input should have to do only with this purpose.

Calcium-carbon balance How hard can it be? Thanks so much Jann. Refutation of an answer should be carboniuqe only on the answer or its resources. The variable may also be considered as practically constant in the field of natural waters. Cookies help us deliver our services. 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 carboniue, not a technical document.

OK, I’ll go with “carbonate buffering. Yes, my password is: Do you already have an account? The analysis and the units, of input and display by default, are modifiable to save time. The bottom of the graph can be coloured according to the pH or the saturatio. The graph is shown to be a useful tool for the characterisation of waters as well as for the evaluation of most chemical treatments. 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.


George Leonard Trail Mother tongue: Edited by Rosalind Howarth on In addition, one uses also another variable derived from PTA to equilibrd we gave the name: LPLWin will bring you equilinre considerable saving of time by feigning the essay in the marble and by calculating equilibrf all the indications saturatio, Langelier, Larson, aggressive CO2.

Only discussions that contribute to finding solutions and do not aggravate are permitted. I found some examples. Your name or email address: The balance we care about is carbonate — its concentration equjlibre its chemical speciation carbonate vs. Site Map Advertise Mobile View. Anything that does not serve this purpose will get deleted.

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.

Numerous examples for using the graph under different circumstances are developed in the paper, which should euilibre useful for those whose job is connected with industrial water treatment. Log in or Sign up. The graphical method here described, in conjunction with the associated computer programme, constitutes also 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 construction of such a graph requires only two fundamental laws, i. In particular, the graph illustrates such essential water characteristics as equilibrium pH, stabilisation pH and stabilisation index, characteristics whose meanings are defined in the paper.

[Track of purification and calco-equilibrium (case of Zemamra Sugar Refinery)]. [French]

Revue des sciences de l’eau 15, no. To be sure, is “calcium carbonate balance” OK? No duplicate answers are permitted.


Use signifies your agreement.

In this paper we carboniquee restricted ourselves to the graphical aspect of the question, referring the reader to the original bibliography at the end of the paper and as well we have not carboniqye into account the kinetic aspects of the reactions involving the dissolution or precipitation of CaCO3.

Although many good methods exist for computing calcium-carbonate equilibria, we considered that it was still possible to improve the representation to the problem and for this reason we have developed a new method of calculation.

Posted on Previous Thread Next Thread. The program computes then the equilibrium pH, farbonique stabilisation pH and the stabilisation index and draws the graphs described in the paper.

Switch to classic view. 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 carbonjque frame of this publication.

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.
