Sanitization of Reverse Osmosis Plant
This Document describes (Standard Operating procedure) SOP for Sanitization of Reverse Osmosis Plant
SOP for Sanitization of Reverse Osmosis Plant
I. Purpose & Scope:
- The Purpose of this SOP is to lay down the procedure for Sanitization of Reverse Osmosis Plant
- This procedure is applicable to all Engineering Department for Sanitization of Reverse Osmosis Plant
II. Responsibilities:
- All Engineering personnel’s shall be responsible to follow and implement this SOP.
III . Introduction and Procedural Part :
Procedure :
- Before starting the R.O. sanitization process initially remove all the sensors of R.O. system (like pH, ORP & Conductivity sensors) & instead of that put blinds.
- Add 5 liters of Mincare solution in the soft water storage tank & add 500 ltrs. of soft water to it.
- Check the pH of sanitization chemical which should be between 2.8 to 3.2. 1 % test strip is provided to check the concentration of solution.
- Connect permeate outlet & reject outlet to soft water storage tank with silicon hose pipe to keep re circulated the chemical during sanitization process.
- Open the valves of permeate & reject to full position.
- Start the RO feed water pump & allow the RO to run for 1.1/2 hr. at 25 to 30% recovery for this adjusts the reject valve.
- Allow the sanitization chemical to charge in the system.
- After the chemical is charged in the system , close RO Feed pump
- Allow the chemical to soak for 2 hrs. After 2 hrs. of soaking, start the flushing of the plant let RO permeate & reject water go drain.
- After 1.1/2 hr. flushing start checking the presence of sanitization chemical & continue flushing until the chemical is totally flushed out. Check the same with test kit.
- After the sanitization is completed, run the plant for 30 mins. & give sample for micro test.
- All data shall be monitored & logged in Annexure I
Frequency:
As And When Required.
