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.
High level of active substance.

Dose

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.

Specific Hazards Arising From Chemical When involved in a fire, this material may decompose and produce irritating fumes and toxic gases (e.g., carbon monoxide, carbon dioxide, phosphorous oxides, and nitrogen oxides).
Special Protective Equipment And
Precautions For Fire-Fighters
Incipient fire responders should wear eye protection. Structural firefighters must wear Self-Contained Breathing Apparatus and full protective equipment. Move containers from fire area if it can be done without risk to personnel. If possible, prevent runoff water from entering storm drains, bodies of water, or other environmentally sensitive areas.

Personal  Precautions       

Uncontrolled releases should be responded to by trained personnel using preplanned procedures. Proper protective equipment should be used. In case of a spill, clear the affected area and protect people.

Protective equipment

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).

Handling

All employees who handle this material should be trained to handle it safely. Open containers carefully on a stable surface. Empty containers may contain residual liquid; therefore, empty containers should be handled with care. As with all chemicals, avoid getting this product ON YOU or IN YOU. Wash thoroughly after handling this product. Do not eat or drink while handling this material. Avoid generating dust of this product. Remove contaminated clothing immediately.
During equipment maintenance follow practices indicated in Section 6 (Accidental Release Measures) to decontaminate equipment or clean-up small spills. Make certain that application equipment is locked and tagged-out safely if necessary. Collect all rinsates and dispose of according to applicable U.S. Federal, State, or local procedures or appropriate local standards.

Storage

Store containers in a cool, dry location, away from direct sunlight, sources of intense heat, or where freezing is possible. Store away from incompatible materials. Material should be stored in secondary containers, or in a diked area, as appropriate. Storage and use areas should be covered with impervious materials. Keep container tightly closed when not in use. If appropriate, post warning signs in storage and use areas. Inspect all incoming containers before storage, to ensure containers are properly labeled and not damaged.

Incompatibilities  Strong bases, oxidizers, and water reactive materials.

Engineering Control

Use with adequate ventilation to ensure exposure levels are maintained below the limits provided in this Section or as low as reasonably achievable. Ensure eyewash/safety shower stations are available near areas where this product is used.

Personal Protective Equipment

Respiratory protection:
None needed under normal conditions of use. Use NIOSH approved respirators if ventilation is inadequate to control mists or vapor. If respiratory protection is needed, use only protection authorized in the U.S. Federal OSHA Standard (29 CFR 1910.134), applicable U.S. State regulations, or the applicable local standards. Oxygen levels below 19.5% are considered IDLH by OSHA. In such atmospheres, use of a full-face piece pressure/demand SCBA or a full-face piece, supplied air respirator with auxiliary self-contained air supply is required under OSHAs Respiratory Protection Standard (1910.134-1998).

Eye protection:
Use approved safety goggles or safety glasses, as described in OSHA 29 CFR 1910.133. Splash goggles with a faceshield may be needed if splash hazards exist.

Hand protection:
Wear chemical impervious gloves

Body protection:
If needed, use body protection appropriate for task (e.g., suit, rubber apron) to protect from splashes and sprays.
