MUSCAT CHEMICAL TAG::
ORG - 191 t (Membrane Antiscalant) combines the product reliability of ORG - 191 t (Membrane Antiscalant) for advanced monitoring and control. ORG - 191 t (Membrane Antiscalant) is a highly effective scale inhibitor whose active components were developed to treat reverse osmosis (RO) systems. ORG - 191 t (Membrane Antiscalant) has shown for over 20 years excellent performance against the following scalants: calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, calcium fluoride, silica and iron.
RO antiscant
Scaling is caused in membranes because the level of hardness salts in the water becomes highly concentrated as it passes through the RO unit. In smaller units scale formation can be prevented by base exchange softening the make-up water but for larger systems that is very expensive. We have developed a range of easy to handle, cost effective RO Antiscalant which increase the solubility of the hardness salts so they remain in solution rather than forming scale on the membrane. Our cost effective RO antiscalants will inhibit a wide range of foulants including: calcium carbonate, calcium sulphate, barium sulphate, strontium sulphate, calcium fluoride, silica and iron.
RO Antiscalants are dosed directly to the RO feed water tank or feed water line (after pretreatment) at the recommended dosage of 1-3 mg/L and maximum dosage at 8mg/L, subject to inlet water quality and parameters is respect of Calcium Hardness, Iron, TDS, Alkalinity, pH and silica content. Maximum dilution should be 10% with RO or DI water for temperature less than 30 deg C. For higher temperature the dilution ratio can increase.

Application and Dosage
Our RO Antiscalant (HIGH PH) is dosed directly to the RO feed water tank or feed water line (after pretreatment) at the minimum recommended dosage of 1ppm and maximum dosage at 15ppm, subject to inlet water quality and parameters is respect of Calcium Hardness, Iron, TDS, Alkalinity, pH and silica content.
In case of high iron content of about 0.5 to 1.0ppm, the dosing has to be increased by 10-15ppm for stabilizing Calcium.
At about 10-15ppm dosage our RO Antiscalant (HIGH PH) is capable of fully inhibiting iron and calcium, and silica up to 166ppm. For higher silica content RXSOL ANTISCALANT should be used.

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).
Scaling and iron fouling of the RO membranes will reduce system performance and lead to premature membrane replacement. Precipitation of scale and deposits build up on the RO membrane, which leads to poor permeate quality, low permeate production, unscheduled downtime, increased water consumption and increased energy costs.
