Ultra-pure water from purified water
The purified water quality required as feed water
Tap water subjected to ion exchange, reverse osmosis or distillation
Optimally, the purified water supplied by a Dofree Pureflow-E/Pureflow-RO system
The content of organic and inorganic substances in the feedwater are reduced to values approaching their limites by the serial combination of high-efficiency of Dofree purification technologies.
