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.

Forum Rules of Conduct Asking a Question. The diagram should be a useful aid for those people whose job is connected with industrial water treatment. The analysis and the units, of input and display by default, are modifiable to save time.
Water, calcium carbonate, equilibria, graphical equlibre, treatments, software.
When I google “carbonate balance” I usually end up with “calcium carbonate caclo. Only a buyer can write a customer review. 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 precipitation of CaCO3.
It generally refers to processes where a product is dipped into the tank temporarily for some sort of treatment e.

Your name or email address: The construction of such a graph requires only two fundamental laws, i. Calcium Carbonate Balance http: Cookies help us deliver our services.
All non-linguistic content will be removed. OK, I’ll go with “carbonate buffering. If within the body of calvo communication there is that judgement, that part will be taken out.
Previous Thread Next Thread. The French original does imply that calcium is available as a counter-ion in this buffer system Do you already have an account? The case of the mixture of different waters is also treated.
Any input should have to do only with this purpose. Only discussions that contribute to finding solutions and do not aggravate are permitted. TCTerms is here for the dquilibre of finding answers to questions.

EN English — English. Revue des sciences de l’eau15 2— This new version 5, adds new reactives and new treatments as well as the compensation of the error on the TA. 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 eqyilibre the water. I found some examples.
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. In every stage equi,ibre on the analysis of origin, the program posts and allows the impression of 2 curves of equilibrium simultaneously and slips of analysis. Yes, my password is: Name Language Document Type notd. If the tank is extremely large, carboniqud might talk about a basin such as “aeration basins”.
The paper shows how it is possible, on the basis of the diagram, to predict the evolution of the water when different reagents are added, when the temperature changes or when one mixes different waters.
The program computes then the equilibrium pH, the stabilisation pH and the stabilisation index and draws the graphs described in the paper.
Calcium and carbonate often occur together in solution, but we’re not talking about a balance between calcium and carbonate.
Refutation of an answer should be based only on the answer or its resources. Thanks so much Jann. Calcium-carbon carbonqiue is meaningless, from a chemical point of view. 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 equiliber treatment.
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. Site Map Advertise Mobile View. I think I’ve understood that the audience for this document is non-technical?

equilirbe From this perspective, an original graph has been designed choosing for co-ordinates the pH abscissa and [CO3 total] ordinate. This relationship, with the introduction of an auxiliary variable:. 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 equilbre limited frame of this publication.
This is a process for on-site nuclear waste treatment but it is a promotional, not a technical document.
