BETAGARD 6000
Premium Antiscalant & Antifoulant
Betagard 6000 is a multifunctional antiscalant and antifoulant for reverse osmosis systems, highly effective in controlling crystallization and particulate fouling on membrane surfaces.
Betagard 6000 will control the scale deposition of CaCO3, CaSO4, BaSO4, and CaF2. Betagard 6000 is formulated to control soluble and insoluble iron and actively disperse particulates. Effective against silica fouling, Hydro 600 is specifically designed for use on Thin Film and CA membranes.
Technical Specifications
| Physical Form | Sp. Gravity at 25 DEG C | pH | Handling and Storage Measures | Packaging |
|---|---|---|---|---|
| Clear colorless liquid. | 1.09 - 1.11 | 5.0 - 6.0 | Keep out of reach of children. In case of accidental splashing, flush with plenty of water. And for eye contact, should receive medical attention as a safety measure. | Available in plastic container size with a net weight of 30 Kg. |
Dosage & Usage Instructions:
Betagard 6000 is an aqueous solution of organic acids and is corrosive in concentrated form. Therefore, corrosion resistant dosing equipment should be used. Examples of suitable materials are 316L stainless steel or plastics such as GRP, PVC and PE. The recommended injection point is into the feed water downstream of filtration equipment and cartridge filters. Betagard 6000 is miscible with water in all proportions.
It can be applied as a neat product, or as a solution in distillate. A minimum dosage solution strength of 10% w/b is recommended. Betagard 6000 should be dosed continuously and in proportion to the feed water flow, to maintain the recommended dosing rate. The dosage rate required depends on the feed water quality and the saturation index of the various scale forming species present in the concentrated brine. The usual range of dosage levels is between 5 - 15 ppm.
BETAGARD 6510
Low pH Membrane Cleaner
Membrane surfaces are a major cause of Reverse Osmosis system failure. Membrane fouling is a common phenomenon involving the deposition of different but related types of foulants on the membrane surface. Betagard 6510 is a low pH membrane cleaner specifically designed for cleaning Reverse Osmosis systems. It effectively cleans inorganic salts such as CaCO3, CaSO4, BaSO4, and metal oxides. Betagard 6510 removes calcium carbonate scale and colloidal metal hydroxides without damaging sensitive polyamide composite membrane elements. Betagard 6510 will restore the cleanliness of the membrane surface and therefore extend the membrane service life.
Technical Specifications
| Physical Form | Specification Specific gravity | pH | Handling and Storage Measures | Packaging |
|---|---|---|---|---|
| Clear liquid with slight odor. | 1.06 - 1.16 | <3 | Betagard 6510 is a fuming liquid and special care should be taken in handling the concentrated form, please handle with care. Avoid contact with eyes, skin or clothing. In case of accidental splashing - flush with plenty of water. In case of contact with eyes, seek medical attention as a safety measure. | Available in plastic container size with a net weight of 30 Kg. |
Dosage & Usage Instructions:
To remove iron and metal hydroxide fouling and calcium carbonate scale. Betagard 6510 should be mixed in a cleaning tank equipped with a mechanical mixer, low pressure recirculation pump, and cartridge or bag filter. This sanitizer works best when applied at temperatures of 40oC- 45oC, pH 2.5 to 3.5, and at flow rates of 8 - 10 gpm per 4" pressurized tube or 30 - 40 gpm per 8" pressurized tube at pressures between 20 - 50 psi. Dilute 1 to 10 with RO permeate water or DI water. Check and adjust pH if necessary. Add Ammonium Hydroxide to increase pH and add more Betagard 6510 to decrease pH. Recirculate solution for 1 hour, checking pH regularly. Turn off the pump and soak for 1 hour. After soaking, recirculate for 20 minutes and then rinse.
BETAGARD 6520
High pH Membrane Cleaner
Foulant accumulation on the membrane surface is a major cause of Reverse Osmosis system failure. Membrane fouling is a common phenomenon that involves the deposition of many different but related types of foulants on the membrane surface. Betagard 6520 is an alkaline cleaner specifically designed for cleaning Reverse Osmosis systems. It effectively cleans colloidal particles, bio-film and organic foulants. Betagard 6520 is typically used in conjunction with Betagard 6510, which is an acidic cleaner, to provide a thorough cleaning process in Reverse Osmosis systems. Both Betagard 6520 and Betagard 6510 will restore the cleanliness of the membrane surface and therefore extend the life of the membrane. Betagard 6520 should be the first step in any cleaning regime. Features:
- Alkaline liquid to remove biological, organic and colloidal fouling without damaging sensitive polyamide composite membrane elements.
- Effective for removing emulsified oils and silica. It should be used after the system shows signs or performance degradation or as a preventative cleaning.
Technical Specifications

|---|---|---|---|---|
| Clear to slightly colored strong alkaline liquid. | 1.06 - 1.16 | <12 | Betagard 6520 is an alkaline liquid and special care should be taken when handling the concentrated form, Avoid contact with eyes, skin or clothing. In case of accidental splashing - flush with plenty of water. In case of contact with eyes, seek medical attention as a safety measure. | Available in plastic container size with a net weight of 30 Kg. |
Dosage & Usage Instructions:
Betagard 6520 should be mixed in a cleaning tank equipped with a mechanical mixer, low pressure recirculation pump, and cartridge or bag filter. This cleaner works best when used at 40oC- 45oC, pH 11.5, and at flow rates of 8 - 10 gpm per 4" pressure tube or 30 - 40 gpm per 8" pressure tube at pressures between 20 - 50 psi. For Silica fouling, use at pH 12. Be careful as pH above 12 can damage membrane elements. Consult your membrane manufacturer for an acceptable cleaning pH range. Dilute 1 part Betagard 6520 into 10 parts RO permeate water or DI water. Check and adjust pH if necessary. Add Sulfuric Acid or Hydrochloric Acid to lower the pH and add more Betagard 6520 to increase the pH. Recirculate the solution for 1 hour, checking the pH regularly. Turn off the pump and soak for 1 hour. After soaking, recirculate for 20 minutes and then rinse.
