RO FEED WATER PRE-TREATMENT SYSTEM BY USING TIAANO’S CHEMICAL FREE ELECTROLYTIC SCALE REMOVER AND DECHLORINATION BY UV IRRADIATION
Based on over 20 years design and manufacturing capacity of MMO coated / DSA activated anode production, Tiaano India established design, supply, installation, commissioning & operation of “Tiaano ElSr-RO” 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
Softeners:
• Hard to sanitize
• Constant salt addition
• Collects contamination
• High water consumption
• Resin attacked by chlorine
• Disposal for the spent softener regenerate
Antiscalant:
• Contamination of Antiscalant 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 stock
Active carbon filter (ACF)
• Closed cylinder with Activated Carbon media
• Generates carbon fines
• High and quick buildup of microorganisms
• Steaming or Hot Water Sanitization is must
Sodium Bi Sulfate (SBS) Injection
• Problematic instrumentation (ORP)
• Low reliability
• High maintenance
• Tendency to over dose
• Fouls the RO membranes
• High water waste
• SBS Contamination common
Chemical Sanitization for equipment
• Dangerous chemical handling
• Post sanitization, validation needed
• High manpower involved
• Uncertain and unreliable results
Our Solution; ElSr-RO Chemical & Media free System:
• Removal of scales by Electrolytic Scale Remover (ElSr)
• Removal of available chlorine by UV radiation(UVDC)
• Continuous bio burden reduction.
