Duplex Eco+ units offer the same features as the simplex Eco+ while providing 24/7 treated water on demand. The Eco+ media takes advantage of a hybrid of different medias including cation and anion exchange resins to reduce problematic contaminants including iron, manganese and hardness.
Eco+ Media is designed for applications where the iron levels are extreme and can’t be removed with normal filter medias. This media is recommended for situations where iron levels are over 30 mg/l as this is designed to reduce levels to within potable standards.
We have done extensive trials with this new media and found it to be the best way of removing iron at extremely high levels. Regular Eco media or manganese dioxide will struggle to reduce the levels to within acceptable levels and will require multiple lead / lag treatment vessels.
Eco+ requires salt as its regenerant as well as a specialist cleaner that will aid in the regeneration of the mechanical structure of the resin. This unit will use a combination of ion exchange media, rather than traditional aeration and oxidation plants. This eliminates the need for a high backwash flow rate and the need for large aeration vessels that can be clogged with oxidised iron.
Each unit includes a metered Clack head to help get the maximum capacity between regenerations and limit the use of salt, keeping running costs low.
