  • What is a dealkalization boiler?
  • Generally, dealkalization can be used to treat water in boilers operating at less than 700 psi, with feedwater containing less than or equal to 50 ppm alkalinity, and with make-up of 1,000 gallons or more per day. Makeup water is the water added to the boiler to offset water lost due to steam and blowdown.
  • Why is alkalinity important in water treatment?
  • The alkalinity of water determines its ability to neutralise acid and alkali, and is an important parameter in achieving a stabilised finished water quality. As water treatment operators will know, the higher the alkalinity of the raw water, the more acid or alkali addition is required to effect a pH change.
  • Why is alkalinity important for the Wheatstone LNG plant?
  • It will also discuss the challenges of designing this system for the Wheatstone LNG plant to be constructed by Xylem Water Solutions (Australia). Alkalinity is important for the coagulation process and in maintaining a stable final water quality that minimises corrosion of the supply pipework.
  • How can raw water alkalinity be reduced?
  • Raw water alkalinity may be reduced using several different methods: Reverse Osmosis – Membrane filtration has become the popular option for boiler water treatment. With appropriate pretreatment, nearly all carbon dioxide can be eliminated from RO-treated feedwater.
