GRADUS
Water Purification System
Fully integrated pure and ultrapure intelligent water system. Superior quality of ultrapure and pure water is achieved directly from a tap water source. Available in 2 configurations – deionization or EDI.
Pre-Clean Pack
High efficiency removal of colloids, particles, free chlorine and minerals for improved system performance.
EDI Module Or DI Pack
Removes remaining ions for consistently superior quality pure water. EDI system requires no maintenance, ensuring low and predictable costs.
Advanced Reverse Onmosis (RO)
Removes 97-99% contaminants including ions, particles, bacteria and organic molecules, reduces feed water consumpt for 60%
Prior to Water Production
Automatic rinsing of the RO membrane and the EDI module ensures that only the highest quality pure water enters the tank.
Attached G1 ultrapure water dispenser -– delivers consistently ion free and low TOC ultrapure water.
Attached G2 pure water dispenser – delivers guaranteed quality Grade II pure water.
Within the tank, pure water quality is preserved by two built in features:
- Vent filter - provides protection against airborn contaminants
- Automatic Sanitization Module – with an integrated UVC regularly irradiates stored water and tank walls, ptreventing bacterial growth and biofilm formation.
Automatic recirculation of stored water through bacteridical UV lamp preserves water quality in the tank and ensures that high quality Grade II water is always on hand ready to use.
Ultra Pack Polishing Cartridge – removes ions and organic contaminants down to trace level.
Oxidation UV lamp – emitting 185 nm, photo-oxidises organic contaminants.
