An evaluation method for scalingretardation behavior of waterquality stabilizing agent by using ultimate carbonate hardness method has been presented

including measurment of scalingretardation behavier

as well as ditermination of evaluation indices

water temperature in test

concentration of waterquality stabilizing agent

and circulating water flow rate of the test facility etc.

and a comparison with the scalingretardation rate method being carried out. Results of test show that the ultimate carbonate hardness method has many advantages

namely having high distinguish ability

good data reproducibility

clear and definite guiding significance

as well as simplicity and applicability etc.

being suitable for evaluating the scalingretardation behavior of waterquality stabilizing agent used in circulating water treament at thermal power plants
