Kleen MCT400

Summary

Product identification

• Product Name: Kleen* MCT400
• Product Type: Membrane biofouling and organic cleaner
• Form: Powder

Description and Use

Kleen MCT400 is a specially formulated membrane cleaner designed for the removal of bio-fouling and organic-based material. It is provided in dry form and contains organic acids, anionic surfactant, and solubilizing actives. This product is recommended for cleaning microbiological fouling, bioproteins, and organic foulants from Desal and Brackish water membranes. It is compatible with PA and CA type membranes.

Treatment and Feeding Requirements

Kleen MCT400 should be used in conjunction with RO-Membrane cleaning CIP equipment. Ensure compatibility with materials of construction.

Preparation and Dilution

Kleen MCT400 is a powder that must be made down (diluted) before circulation into the membrane system.

• Recommended Dilution: One pound (0.45 kg) per 5 gallons (19 L) of total CIP volume.
  • Total CIP water volume includes the water volume in the CIP tank and the RO system piping.
• Table of Concentration, pH, and Conductivity:

General Cleaning Instructions

1. Inspect and clean the cleaning tank, hoses, and cartridge filters. Install new cartridge filters.
2. Fill the cleaning tank with RO permeate or DI water. Turn on the agitator or tank recirculation pump.
3. Slowly add the recommended amount of Kleen MCT400 to the cleaning tank and mix thoroughly.
4. Check and adjust solution temperature. Do not exceed 95°F (34°C).
5. Check and adjust solution pH to be between 2.0 and 3.0, or as recommended by the membrane manufacturer. Adjust upward with NaOH or downward with hydrochloric acid if necessary.
6. Circulate the solution through one stage at a time in the direction of feed flow for 30 minutes.
   • Circulation flow rate should be as recommended by the membrane or system manufacturer.
   • Operating pressure should be low enough to minimize permeate production, always less than 60 psig (4.2 kg/cm²).
   • For heavy fouling, divert the first return flow (up to 15% of tank volume) to drain.
   • Clean each stage separately in a multistage system.
7. If the cleaning solution becomes turbid or discolored, dump the tank and prepare a fresh solution. Replace solution if pH or temperature moves out of the recommended range.
8. Rinse with RO permeate water before returning the system to service.
9. When returning the unit to service, divert product water to drain until residual cleaning solution is rinsed from the system.

A soak period may be necessary depending on the fouling type.

Storage and Handling

Use corrosion-resistant equipment (e.g., PVC, cross-linked polyethylene) for storage and preparation. Pumping materials must also be corrosion-resistant.
