The Purified Water generating plant is formed by two different parts, the inverse osmosis and the deionizer.
a) Inverse osmosis
The osmosis feed is with pre-treated water, with particles no larger than 50-60 microns.
It is vital to check that the water from the descale for the osmosis feed is 0ºHTF hardness.
The osmosis stage is formed by:
- A pressurizing pump fed from the electro-deionizer
- The membrane containers is formed by a set of a theoretical osmosis of a single tube, configured according to the production of the plant. According this configuration, the hydraulic yield of this system corresponds to 40% of permeate and 60% of rejection water.
The electro-deionizer is the part dedicated to the ionic and bacterial treatment of the osmotized water. The EDI contains a complete electrical panel with a PLC that monitors the operation of the entire Purified Water production plant. A touch-screen is used to as a HMI.
