ELSR – RO CHEMICAL & MEDIA FREE SYSTEM

April 26, 2019 at 5:21 PMadmin

 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.

Our Solution; ElSr-RO Chemical & Media free System:

•          Removal / Reduction of scales by Electrolytic Scale Remover (ElSr).

•          Removal of available chlorine by UV radiation (UVDC).

•          Continuous bio burden reduction.

•          Hot Water Sanitization.

•          Green Technology.

 

PFD of Tiaano ElSr-RO

 

•          Electrically powered and  separation of scale in Reactor

 

•          Partial electrolysis to change dynamic equilibrium conditions.
