Drinking Water Plants: Re-Mineralization of Desalinated Seawater  and Mineralization Soft Water from Surface Sources

Mineralization facilities are an integral part of seawater and brackish water desalination plants, as well as surface and groundwater treatment installations.


      Global cumulative investments in desalination plants reached roughly $21.4 billion in 2015 and should reach nearly $48.2 billion by 2020, with a compound annual growth rate (CAGR) of 17.6%.


  • A compound annual growth rate of investments in re-mineralization at desalination plants only ( adding calcium only ) is estimated at more than 20%.  Emerging markets are China, India, and the USA.


  • The cost of re-mineralization installation at seawater desalination plant is estimated at 5 - 7% of a total cost of the entire seawater desalination installation, while in brackish water desalination plants its relative cost can be as high as 15% and in Surface Water Mineralization installations – up to 50%.


  • The global market volume of desalinated water re-mineralization is estimated above US$ 2.5B/y.


  • Market volume of mineralization ( hardening) soft water from surface sources is assessed as       US$ 1B/y.
