A minimum value for alkalinity for adequate protection is 200 PPM. High boiler alkalinity, which is in excess of 700 PPM, should be avoided. Values higher than this can lead to embrittlement of the steel. Phosphates. Phosphates are used to react with …
Hardness - Hard water does not foam. However, boiler water is deliberately softened to prevent scale formation, and this gives it a propensity to foam. Colloidal substances - Contamination of boiler water with a colloid in suspension, for example. milk, causes violent foaming. Note: Colloidal particles are less than 0.000 1 mm in diameter, and can pass through a normal filter.
