RXSOL Membrane Antiscalant ALKA 191T : RO ANTISCALANT

• Minimizes carbonate and sulphate scaling, reducing system fouling and lowering cleaning costs.

• Eliminates the need for acid dosing in many applications, improving safety and simplifying operations.

• Compatible with all membrane types based on polyamide chemistries, ensuring broad application flexibility.

• Acts as an effective iron sequestrant, preventing iron deposition and fouling.

• More stable and effective than sodium hexametaphosphate and most conventional polymeric antiscalants, delivering superior long-term performance.

ORG - 191 t (Membrane Antiscalant) is used when the silica level in the brine is less than 185 mg/l at a brine pH of 7.5 and temperature 25oC (77oF). For higher silica levels, the recommended product is ORG - 191 t (Membrane Antiscalant).

ACTIVE CONSTITUENTS

Proprietary Sequestering Agent

COMPATIBILITY

This product has Standard 60 in the reverse osmosis antiscalant category.

MATERIALS OF COMPATIBILITY

 All membrane elements based on Polyamide chemistries including

Thin Film Composite (TFC) membranes when used as directed

* O-rings are acceptable for static applications. If fitting is opened, O-ring must be replaced.

DOSAGE AND FEEDING

ORG - 191 t (Membrane Antiscalant) be fed continuously to minimize precipitation of scale and fouling of RO and nanofiltration membranes. The feedpoint location should be as close to the RO membrane as practical but one that ensures good mixing with the feedwater prior to entering the RO system. Typically, this is before the cartridge filters.

All new installations of ORG - 191 t (Membrane Antiscalant) should begin with a 2 week monitoring phase during which current operating conditions should be maintained (i.e. setting pumps manually based on stroke length and frequency). After this evaluation period, TRASAR-based control of the system should be instituted using the recommended pump.

It is preferred to feed ORG - 191 t (Membrane Antiscalant) neat via a closed feed system to prevent contamination from foreign material (a closed feed system being defined as a system in which fluid is moved from a closed storage vessel into a treated media without exposure to the atmosphere, except through normal venting or pressure relief devices).

ORG - 191 t (Membrane Antiscalant) can be diluted using RO permeate (only) following these guidelines:

1. Use RO permeate for dilution.
1. Prepare a fresh antiscalant solution every 3-5 days.
1. Inspect the antiscalant day tank before adding the new solution. If needed, the antiscalant tank should be cleaned prior to filling.
1. Dilution rates up to a factor 10 are typically applied. Dilution factors higher than 10 will require more attention with respect to the condition of the antiscalant tank (cleaning) and preparation of a new solution (every 1-3 days).
1. NaOH can be added to the dilution to increase the pH to 10-11. This is especially recommended for warm environments to prevent bio-growth.

ORG - 191 t (Membrane Antiscalant) dosage is dependent on feedwater chemistry, membrane type, and system operating parameters (e.g., recovery, temperature and pressure). These parameters determine the potential foulant that is likely to foul the membrane elements.

To determine the optimum product dosage for your system, it is recommended that you use the RO Optimizer chemical projection computer program. This program will select the appropriate scale inhibitor treatment program and calculate the recommended dosage based on the RO design and operation as well as feedwater or brine chemistry. This program will do all calculations for you easily and automatically.

CONSEQUENCES OF OVERFEED
Overfeed of ORG - 191 t (Membrane Antiscalant) will result in a higher chemical cost.

CONSEQUENCES OF UNDERFEED
Underfeed of ORG - 191 t (Membrane Antiscalant) will result in poor scale inhibition. This will lead to fouled RO membranes, and reduced system performance and/or premature membrane replacement. In RO units, scaling is typically seen in the tail-end elements that have the highest reject concentration (4:1 for a 75% recovery system).

PHYSICAL & CHEMICAL PROPERTIES

These properties are typical. Refer to the Material Safety Data Sheet (MSDS) SECTION 9, for the most current data.

RXSOL Membrane Antiscalant ALKA 191T is specially designed for use in Reverse Osmosis (RO) systems as a high-performance antiscalant, providing effective protection against scale formation and membrane fouling.

RXSOL Membrane Antiscalant ALKA 191T, enabling precise dosage monitoring and control to safeguard the system from both under-dosing and over-dosing, ensuring optimum performance and extended membrane life.
