REVERSE OSMOSIS MEMBRANE CLEANER : low pH cleaner formulated to remove severe calcium carbonate scaling and moderate metal fouling and metal-organic Complexs
RO membrane cleaners is specifically designed to remove iron fouling for silica. It also has effectiveness against calcium carbonate scaling. RXSOL-33-3304-025 performance can be enhanced by adding low / high ph cleaners to the cleaning solution although some minor ph correction may be necessary. It should always be used as recommended by the membrane manufacturer or equipment supplier, in respect to cleaning ph and temperature. it also contains organic dispersants that helps to break down colloidal clay deposits and imparts better efficacy to biocides by penetrating into films. it is specifically developed for removing iron, silica, metal silicates, metal oxides/hydroxides and other colloidal/particulate based foulants from ro membranes. It is also effective to remove calcium carbonate, calcium phosphate and silt.
As RXSOL-33-3304-100 is buffered, the cleaning solution will stabilise at pH 3.6.

Treatment and Dosage Requirements
Cleaning solutions should be prepared with chlorine free product water to give a 4% w/w solution, or 1 kg of RXSOL-33-3304-025 to every 25kgs of water. As RXSOL-33-3304-025 is buffered the cleaning solution will stabilize at pH 3.6.
Deposition of fouling and scale directly affect the cleaning time In general practice to dissolve complete fouling 2 to 3 hours required . During chemical reaction between solution and deposition If the cleaning solution becomes brown to red in color it must be changed as the solution becomes completely non reactive.
On completion of cleaning process membrane should be clean with cupious amount of FRESH WATER till neutralisation of pH value of runing water.
For disposal of RXSOL-33-3304-025 cleaning solution should always be neutralized with alkali.

|
Skin exposure |
If this product contaminates the skin, immediately begin decontamination with running water. Remove exposed or contaminated clothing, taking care not to contaminate eyes. Victim should seek immediate medical attention if any adverse exposure symptoms develop. |
|
Eye exposure |
If this product enters the eyes, open victim's eyes while under gently running water. Use sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is for 15 minutes. Victim must seek medical attention. |
|
Inhalation |
If mist of this product are inhaled, remove victim to fresh air. If necessary, use artificial respiration to support vital functions. Remove or cover gross contamination to avoid exposure to rescuers. |
|
Ingestion |
If this product is swallowed, CALL PHYSICIAN OR POISON CONTROL CENTER FOR MOST CURRENT INFORMATION. DO NOT INDUCE VOMITING. Have victim rinse mouth with water, if conscious. Never induce vomiting or give a diluent (e.g., water) to someone who is unconscious, having convulsions, or unable to swallow. If contaminated individual is convulsing, maintain an open airway and obtain immediate medical attention. |
| Most Important Symptoms/Effects |
Immediate: Inhalation exposure may cause coughing or sneezing. Symptoms of skin and eye contact may include redness and irritation. Ingestion may cause stomach pains, cramps, and gastritis. Delayed: Prolonged or repeated skin overexposure to this product may cause dermatitis (dry, red skin). Symptoms may include tingling, redness, and visible injury. |

For small releases ( 20 L), clean up spilled liquid wearing gloves, goggles, faceshield, and suitable body protection. The minimum Personal Protective Equipment recommended for response to non incidental releases (more than 20 L) should be Level C: triple-gloves (neoprene gloves and nitrile gloves over latex gloves), chemical resistant suit and boots, hard hat, and full-face respirator with acid mist and HEPA filter. |
| Emergency procedures | Monitoring must indicate that exposure levels are below those provided in Section 8 (Exposure Controls-Personal Protection) and that oxygen levels are above 19.5% before anyone is permitted in the area without Self-Contained Breathing Apparatus. |
| Methods and Materials for Containment and Cleaning Up | Vacuum or soak- up solids liquid for recovery/disposal. Neutralize residue with sodium bicarbonate or other neutralizing agent for dilute acids. Decontaminate the area thoroughly. Test area with litmus paper to ensure neutralization. Place all spill residues in a suitable plastic container. Dispose of in accordance with applicable Federal, State, or local procedures, or appropriate local standards (see Section 13, Disposal Considerations). |
