BASIC WATER TREATMENT OF STEAM BOILERS

water by softeners. Their removal dramatically reduces the possibility of boiler scale formation. Water softening can be performed by ion exchange, whereby favorable sodium ions are exchanged for unfavorable calcium and magnesium hardness ions by the ion exchange resin beads. Eventually, the softener resin bed exhausts (fills up with

Sodium Monitoring TECHNICAL NOTE On Power Plant

Typical levels of sodium in river water would be approximately 30mgkg-1, and in sea water, approximately 12,000 mgkg-1. Nearly all sodium compounds are water soluble, and in the high purity waters (i.e. very dilute solutions) found in power generation plants, these compounds are dissociated into ions. In the case of sodium chloride (NaCl), into
