Crystal Right works by an ion exchange process which removes iron, manganese and hardness. The minimum pH requirement is 6.0 and Crystal Right will raise the pH in these acidic waters. Crystal Right works at its best on clear water, i.e. when the iron/manganese are in a dissolved form. Crystal Right will also remove hardness with no extra treatment. Ammonia, lead, hydrogen sulphide and copper can also be reduced. The media bed can be sanitised with chlorine from time to time. The regeneration process is exactly the same as that used in a water softener and requires regeneration with salt (sodium chloride). There are two types of Crystal Right. CR100 is used where the pH is between 6 and 7 and will increase the pH. CR200 is used where the pH is 7 or above. Crystal Right has a number of advantages over conventional systems in that pH correction, iron/manganese removal and softening can all be addressed in a single process.
