6.5. Chemical Cleaning and Sanitization Precautions
· Avoid direct skin contact with cleaning chemicals. Use appropriate
Personal Protective Equipment (PPE), such as safety glasses,
gloves and protective clothing. Consult SDS from chemical
supplier, or International Chemical Safety Card if available. See
https://www.ilo.org/safework/info/publications/WCMS_113134/l
ang--de/index.htm .
· Flush all hoses and rinse tank with clean water BEFORE adding chemicals.
· Pressure-test CIP system and connecting hoses with water before adding chemicals
to tank.
· To reduce the possibility of chemical sprays, relieve the pressure in chemical lines
before disassembly.
· Follow the manufacturer’s chemical safety instructions on the
container labels.
· Check the pH level in any solution before letting it flow to the drain. Adjust pH as
required to comply with any discharge restrictions.
· Do not run a cleaning solution through the system when DC power is applied to the
module. Make sure the DC power is off before cleaning.
6.6. Typical Procedure for Cleaning or Sanitization
NOTE: The following cleaning procedure is based on the CIP system shown in Figure 6-
1. If your CIP system is different, you may need to adapt this procedure.
6.6.1 Preparation
· Turn off the DC power supply.
· Drain most of water from the CEDI system (to avoid dilution of cleaning solution).
· Close the CEDI system feed valve and product valve.
· Connect the discharge of the cleaning pump to the LX system feed CIP connection.
· Install new filters in CIP system.
· Connect the CEDI system reject and product CIP connections to the cleaning tank.
· Verify that all piping connections are secure.
· Close cleaning pump discharge valve until ready to pump the cleaning solution into
the LX system.
6.6.2 Cleaning
· Follow the instructions in Section 6.6.1 (above) to prepare the LX system for chemical
