“Ozone”. The most expensive but very effective method of filtering water is through Ion Exchange. It involves replacing ions like Ca2+ and Mg2+ (harmful) with good ions like Na+ or K+. Ca2+ can cause cell injuries and trigger a number of membrane-disruptive processes while Mg2+ in all of its forms greatly increases SRB (Sulfate Reducing Bacteria) growth. SRB causes extreme cases of corrosion and sabotage in water cooling‚ heating‚ and filtering systems. Meanwhile Na+ and K+ are ions that “transport
