Water hardness is the main factor to form the scale and affect the quality of products. In fact, the total hardness is mainly the hardness of calcium and magnesium ions. The general water hardness unit is mmol / L, but different countries have used different units, the following is the conversion tables of these water hardness units.

In the case of industrial process contamination, it is possible for organic contaminants to decompose under boiler temperature and pressure to form organic acids. Sugar is an excellent example of an organic which, when returned in a large quantity, can cause rapid loss of boiler water alkalinity and reduce pH of the boiler water to 4.3 and lower.

Measuring Conductivity of RO Water | Reverse Osmosis

Jul 12, 2017 · Seawater has a conductivity of 50 mS/cm, and drinking water has a conductivity of 200 to 800 µS/cm. The permeate of an RO unit varies based on the feed concentration and operating pressure. Typically, the conductivity of RO water should fall between the value for deionized water and the value for drinking water (0.05 µS/cm-200 µS/cm).
