The interactive configurator needs JavaScript. The treatment sequence Mango Pie builds from is: coarse sediment pre-filter, fine sediment filter, iron removal where required, hardness control where required, activated carbon, micron guard cartridge, booster pump, RO membrane with a reject line to drain, TDS blend and mineral correction, UF where required, storage, post-carbon polishing, UV where required, and the outlet. Send us an enquiry and a person will go through it with you.
