CHEMICAL CLEANING PROCEDURES

The membrane plates are fragile. Care must be used in cleaning them. Carefully follow the

instructions below. Always keep the membrane plates thoroughly wetted.

Only authorized service personnel are to perform chemical cleaning on the BioBarrier.

Hazardous chemicals and infectious waste material are present when cleaning the system.

Proper protective clothing, equipment and practices must be implemented when attempting the

procedures described below.

CIP (CLEAN IN PLACE) PROCEDURE

The following procedure is to be performed for each membrane

module/stack in the entire system.

Shut OFF air to unit(s) to be cleaned.

Open ball valve on vent/CIP pipe to membrane's discharge pump.

Mix chlorine cleaning solution

a. Each single stack module - Premix 0.8 L (~1/4 gal) household bleach (5.2 – 6.2% NaOHCl (sodium

hypochlorite)) into 10 gallons of tap water. Warm water is best (~80°F/26°C).

Use a funnel to pour this mixture into the CIP pipe.

Close CIP pipe ball valve.

Let the unit sit NOT RUNNING for at least 4 hours (longer is better).

After 4 hours, turn ON the power to the unit (should return to AUTOMATIC operation).

INTENSE OXIDATIVE CLEANING PROCEDURE:

Chlorine and chlorine gas can be lethally toxic. Proper safety precautions as detailed in the Material Safety Data Sheets for the chemical being used must be

followed. Use ONLY the substances mentioned in these instructions. Using additional substances could be lethally hazardous.

Remove membrane unit from the aeration tank. Remove the membrane module from its housing.

Carefully remove any large solids or sludge cake from the surface of the membrane by rinsing each membrane plate with a garden hose.

NOT

touch the surface of the membrane sheet with any foreign substance including a hand.

Prepare a chlorine cleaning solution in a container large enough to fully submerge the membrane module. For every 10 gallons of water mix 0.8

L (~1/4 gal) household bleach (5.2 – 6.2% NaOHCl (sodium hypochlorite)). Typically, 30 gallons of water is needed per module for complete

submergence of the module.

Soak the membrane modules in this solution for a minimum of four (4) hours. The entire module must be submerged for the entire cleaning

period.

Perform citric acid cleaning procedure, if necessary. Place the cleaned membrane back into the aeration tank.

The membrane plates
