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 …

What is the Impact of an RO on a Boiler Water Treatment

Make-up water enters the boiler and by dilution the conductivity is lowered. This balance is referred to as cycles of concentration (COC) or concentration ratio. Simply put it is the difference of the total dissolved solids or TDS in the make-up water vs the level in the boiler. The higher the COC results in the least amount of waste.
