Water for the Boiler | Spirax Sarco

If the pH value is too high, and the water is alkaline, other problems such as foaming may occur. Caustic embrittlement or caustic cracking must also be prevented in order to avoid metal failure. Cracking and embrittlement are caused by too high a concentration of sodium hydroxide.

pH - Wikipedia

Solutions with a pH of 7 at this temperature are neutral (e.g. pure water). The neutral value of the pH depends on the temperature, being lower than 7 if the temperature increases. The pH value can be less than 0 for very strong acids, or greater than 14 for very strong bases.

Water Treatment Coagulation | Water Treatment | Waste

This is fed usually in solution form with strength of 4 to 8 %. The alkalinity and pH value of natural water are too low to react with copperas to form the desired ferric hydroxide floc, because the reaction involves oxidation by the dissolved oxygen in the water, which does not occur when pH value is less than 8.5.

Boiler Water Tests | Viking Water Technology, Inc.

May 04, 2016 · Since the pH scale is logarithmic, each change in pH value by a whole unit indicates a 10-fold increase in acidity or basicity. For example, at pH 6 there is 10 times more acidity than at 7. pH 5 is 100 times more acid than pH 7. Similarly, pH 8 is 10 times more basic (alkaline) than pH 7 and pH 9 is 100 times more basic than pH 7, and so on.

Water Handbook - Measurement of Steam Purity | SUEZ

Sodium Tracer Technique. Another commonly used method for measuring steam purity is the sodium tracer technique. This technique is based on the fact that the ratio of total solids to sodium in the steam is the same as the ratio of total solids to sodium in the boiler water for all but the highest-pressure (greater than 2400 psig) boiler systems.
