1.0 PURPOSE AND SCOPE

1.1 Purpose

This procedure provides instructions for chemical cleaning and for laying up the rough

and fine filters.

1.2 Scope

This procedure provides instructions to use chemical cleaners made up in the CIP tank for

cleaning the fine and rough filters. These systems are also used for chemical solution

layup of the two filters.

Fine and rough filter backwash and use of the CIP tank for RO cleaning are not in the

scope of this procedure.

2.0 INFORMATION

2.1 Terms and Definitions

CIP - Clean-in-Place

EDTA - Ethylenediaminetetraacetic Acid

H2O2 - Hydrogen Peroxide

RO - Reverse Osmosis

SWRT - Secondary Waste Receiving Tank.

2.2 General Information

2.2.1 This procedure is written for cleaning either the rough or fine filter. Valving

associated with performing the rough filter cleaning are in “( )” and valving

associated with the fine filter cleaning are in “[ ]”, or are identified in valving

tables as either rough filter or fine filter valving.

2.2.2 Observe MSDS/SDS PPE requirements for the cleaning chemicals.

2.2.3 Chemical spills are to be reported immediately to the CRO.

5.0 PROCEDURE

Special Instruction

Draining of the CIP filters may be performed at any time per Section 5.10.

NOTE - Each cleaning evolution consists of:

Charging filter and transfer lines (Section 5.4)

Adding and recirculating cleaning chemical(s) or layup chemical (Section 5.5),

and one or both of the following:

Draining cleaning chemical(s) from (rough) [fine] filter and transfer lines

and CIP equipment (Sections 5.6, 5.7, and 5.8)

Draining layup chemical from transfer lines and CIP equipment, but not

from (rough) [fine] filter (Section 5.9).

- Some cleaning events require more than one cleaning evolution. A different chemical

may be needed or the cleaning evolution may be repeated with the same chemical, as

prescribed by Process Memo.

- Sodium EDTA may be used as either a cleaning chemical or a layup chemical.

- To avoid excessive foaming in Sump Tank 2, the RO/filter cleaning switch is toggled

to maintain sump tank level between 40 and 50%.

- Due to the infrequent use of rough filter, its operation includes a separate step for

activating a “Rough Filter Normal Operation” permissive switch on graphic Rough,

before valve positions can be changed.

- SOM determines component lineup requirements.

5.1 Valve Lineup Determination

5.1.1 (SOM) DETERMINE which valve lineup Checklists/Data sheets need to be

performed.

5.1.2 (SOM) IF valves are known to be in the required position and do not require

verification, INITIAL/DATE AND DOCUMENT reason in the comments

section of the Checklist/Data Sheet.

5.1.3 (SOM) IF valves are not in the required position because of an existing

process (i.e., LOTO, Caution Tag, Work Package, Administrative Lock,

Facility Tag or Status Seals), MARK N/A on the Checklist/Data Sheet AND

INITIAL/DATE AND DOCUMENT reason in the comments section of the

Checklist/Data Sheet
