Tiaano a well established company in India introduced Chemical free RO feed water pre-treatment system an combination of Electrolytic Scale Remover and Dechlorination by UV irradiation.
Critical Problems in Bottling, Power & Pharma Water:
Scale precipitation in RO.
· Chlorine / Sodium hypochlorite removal before RO.
· Biological & Algae growth.
a. Softeners:
· Hard to sanitize
· Constant salt addition
· Collects contamination
· High water consumption
· Resin attacked by chlorine
· Chlorine needed to keep clean
· Disposal of spent softener regenerate
b. Antiscalant:
· Contamination of Anti-scalant is common
· Hard to control, susceptible to feed fluctuations
· Proof needed of no presence in permeate
· Possible problems of concentrate disposal
· When dosing interrupted, system fails
· System typically cleaned frequently
· Maintaining Anti-scalant in stock
·
c. Sodium Bi Sulfate (SBS) Injection – Chlorine removal
· Problematic instrumentation (ORP).
· Free chlorine removal to protect RO & CDI.
· Low reliability.
· High maintenance.
· Tendency to over dose.
· Fouls the RO membranes.
· High water waste.
· SBS Contamination common.
d. Chemical Sanitization for equipment – Biological & Algae.
· Dangerous chemical handling.
· Post sanitization, validation needed.
· High manpower involved.
· Uncertain and unreliable results.
e. Ground water / City water / Raw water contamination.
· Self-Contradictory of Raw water, it becomes a contaminated, when it comes from ground or city water supplies.
