RO Water Chemistry - Hydranautics

2016-12-9 · RO Water Chemistry Alkalinity: Alkalinity is comprised primarily of bicarbonate, carbonate and hydroxide ions. Naturally occurring alkalinity functions as the earth's natural buffering system. An example of this buffering capability occurs when small doses of strong acids (e.g. acid rain) react with the alkalinity in water. The

Foaming and priming in boilers - Lenntech

Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain types of
