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.

Calcium-carbon balance How hard can it be? Comments Merci a tous! Download the article in PDF to read it.
He specifies the quantities of necessary products for any correction of a parameter, such as the pH, the calco-carbonic balance, the TA, the putting in the balance with the atmosphere, the remineralization In addition, one uses also another variable derived from PTA to which we gave the name: We would talk about the carbonate balance, or better yet, “carbonate buffering. Revue des sciences de l’eau15 2— The balance we care about is carbonate — its concentration and its chemical speciation carbonate vs.
Revue des sciences de l’eau 15, no. The bottom of the graph can be coloured according to the pH caco the saturatio. He allows to solve in a few seconds the equations of the calco-carbonic balance allowing to characterize waters. The variable may also be considered as practically constant in the field of natural waters. 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 carboniquee with calcium carbonate.
LPLWin logiciel calco-carbonique Software for resolution of the calco-carbonic equilibrium The LPLWin software allows to characterize waters face to face of the cargonique balance, so allowing to predict and to correct the problems of scaling, aggressiveness and corrosion of materials in contact of the water. This is a process for on-site nuclear waste treatment but it is a promotional, not a technical document. Calcium and carbonate often occur together in solution, but we’re not talking about a balance between calcium and carbonate.
No duplicate answers are permitted. Use signifies your agreement. I found some examples. Name Language Document Type notd. The analysis and the units, of input and display by default, are modifiable to save time. I think I’ve understood that the audience for this document is non-technical? The asker selected one carboique several most wquilibre answers. No, create an account now.
It generally refers to processes where a product is dipped into the tank temporarily for some sort of treatment e. If you see a lot of google occurrences, they’re related to balancing equiljbre, or to a specific biological system If a message involves judgment of a peer, criticism or defence of that peers competence, judgmental remarks, that message will be deleted. To be sure, is “calcium carbonate balance” OK? This new version falco, adds new reactives and new treatments as well as the compensation of the error on the TA.
In this paper we have 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 taken into account the kinetic aspects of the reactions involving the dissolution or carbonoque 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.
Or are you suggesting “carbonate balance” on its own?

If within the body of a communication there is that judgement, that part will be taken out. LPLWin will bring you a considerable saving of time by feigning the essay in the marble and by calculating you all the indications saturatio, Langelier, Larson, aggressive CO2.

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.
Mail comments and suggestions to TranslatorsCafe. We have taken advantage of this property to build up two networks of curves that make up the overall graph, i.
The case of the mixture of different waters is also treated. Thanks so much Jann. 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.

This was my guess but only gets 5 hits on Google so I’m not sure. Forum Rules of Conduct Asking a Question. Numerous examples for using the graph under different circumstances are developed in the paper, which should be useful for those whose job is connected with industrial water treatment.
The French original does imply that equilbre is available as a counter-ion in this buffer system Eequilibre construction of such a graph requires only two fundamental laws, i. Log in or Sign up. If the tank is extremely large, you might talk about a basin such as “aeration equulibre. If you want to be accessible to those who don’t know what buffering is, I would avoid the ambiguity and go for “carbonate balance” without “calcium.
