Summary
Product Identification
- Product Name: RoClean L404 Green
- Product Type: Liquid cleaner
- Manufacturer: Avista Technologies, Inc. (Mentioned as manufacturer of RoClean L404)
- Intended Use: To remove metal foulants from reverse osmosis (RO) and nanofiltration (NF) membranes.
Specifications
- Appearance: Pale yellow liquid
- pH (2% solution): 3.5-4.5
- Specific gravity (@25°C): 1.15-1.25
Performance Benefits
- A specialized blend of proprietary buffers, chelants and reducing agents to dissolve metal deposits.
- Highly effective against metal hydroxides, calcium carbonate and iron.
- Environmentally friendly formulation that is free of phosphate and EDTA.
- Certified for offshore use.
- Highly buffered to resist pH changes during the cleaning process.
- Compatible with polyamide and cellulose acetate elements.
- Suitable for use with other Avista cleaners.
Cleaning Instructions
- Dilution: 2% wt/wt for moderate to severe fouling, 1% wt/wt for mild fouling.
- Water Quality: RO permeate or deionized water.
- Temperature: Heat to the maximum acceptable temperature as per membrane manufacturer guidelines.
- Recirculation: Recirculate through cleaning tank for mixing.
- System Flow: Run through each RO system stage, one at a time, for a minimum of 60 minutes at the flow rate recommended by the membrane manufacturer.
- For 4-inch diameter elements: 10 gpm (2.4 m³/hr) per vessel.
- For 8-inch diameter elements: 40 gpm (9.0 m³/hr) per vessel.
- Heavy Fouling: Discard up to 15% of solution if discolored or turbid. Soaking up to 8 hours may be beneficial.
- pH Monitoring: Monitor pH during cleaning. If pH rises, prepare a new batch.
- Rinsing: Rinse membranes by flushing with RO permeate after cleaning is complete.
Packaging and Storage
- Formats: Pail, Drum (200 kg), IBC tote (1200 kg). (Note: Specific packaging formats may vary by region).
