Sanitization of purified water storage tank.

This Document describes (Standard Operating procedure) SOP for Sanitization of purified water storage tank and Distribution Loop

SOP for Sanitization of purified water storage tank and Distribution Loop

I. Purpose & Scope:

• The Purpose of this SOP is to lay down the procedure for Sanitization of purified water storage tank and Distribution Loop
• This procedure is applicable to all Engineering Department for Sanitization of purified water storage tank and Distribution Loop

II. Responsibilities:

• All Engineering personnel’s shall be responsible to follow and implement this SOP.

III . Introduction and Procedural Part :

Procedure ( Manual Mode )

• Switch on the control panel, operate the switch to manual position.
• Check and conform the sufficient water available in the tank (minimum 1/3 of capacity)
• Start the circulation pump and circulate the water through circulation loop.
• Open the steam inlet valve of the jacket heat the water till the water temperature attain the 80 Degree Celsius.
• UV lamp should be closed during sanitization.
• Check the circulation pump water attains the temperature of 80 Degree Celsius in the return line by temperature sensor.
• Start count the time of sanitization of tank and loop system. Which is 45 mins.
• After compilation of circulation of hot water, drain the water of the system and tank.
• Collect the fresh water.

Frequency :

15 days or as and when required.

Procedure : (Auto Mode)

• Set the level in the purified water at medium level or below medium level. Switch on the normal- sanitization mode two switches on control panel to sanitization mode.
• The distribution pump should start.
• The actuated steam valve should open.
• After achieving temperature sanitization cycle must stop after 45 minutes giving an alarm on the screen.
• Sanitization cycle should stop by pressing STOP in sanitization mode
