Comment on Desalination system could produce freshwater that is cheaper than tap water

  limestone deposited by water leads to a hard, not easy to remove build up as it will not readily redissolve into any water, unlike salt, that will gladly let its self be dissolved via osmotic pressure until the maximum salinity of water is reached

  seawater for example has around 34-35 ppt salt, water is satisfied at around 260ppt, meaning that one saltwater flush of the system will clean out basically all the salt of like 7 prior runs
