Antiscalant RO

Antiscalant RO is a high-performance scale inhibitor specifically designed for reverse osmosis (RO) systems. Scientifically formulated to protect and maintain RO membranes, it also serves as an effective cleaner for water softener resins and can be used as a preventative treatment to prolong system life and efficiency.

Compatible with the polyamide and cellulose acetate RO membranes of the leading manufacturers.

This versatile formulation is particularly effective in systems prone to scale formation and iron fouling. In both RO and water softening applications, RXSOL-33-3302 delivers reliable performance, helping to maintain optimal flow rates and water quality. Highly effective for alkaline RO permeate, or where water to be treated is alkaline.

Traditionally, scale buildup and iron deposits on RO membranes have led to reduced permeate output, declining water quality, unexpected system downtime, and higher operating costs—ultimately resulting in early membrane replacement. RXSOL-33-3302 addresses these challenges with a powerful phosphonate-based chemistry that solubilizes iron contamination within sodium ion exchange resin beds.

Extremely helpful for antiscaling against:

Calcium Carbonate:CaCO3
Calcium Sulfate:CaSO4
Barium Sulfate:BaSO4
Strontium Sulfate:SrSO4
Calcium Fluoride:CaF2
Sodium Fluoride:NaF
Iron:Fe

Application and Dosage

Should be continuously dosed into the feedwater upstream of the membrane system, typically at a rate of 3–6 mg/L, depending on the feedwater quality and specific system conditions. Our technical consultants are available to recommend the optimal dosage tailored to your system's requirements.

For best results, it is advisable to operate the dosing pump at the highest possible frequency, adjusting the stroke length to fine-tune the dosing rate and ensure consistent membrane protection.

An additional benefit of RXSOL-33-3302 is its compatibility with RO permeate for dilution, with fresh solutions recommended every 3–5 days to maintain efficacy.

When used in ion exchange softener resin beds, the recommended dosage is 1/3 litre per 25 kg of salt added to the brine tank.

Industrial Efficiency Booster: How RO Antiscalants Enhance Reverse Osmosis System Performance

In large-scale industrial operations—like power plants, chemical manufacturing, food processing, and pharmaceuticals—Reverse Osmosis (RO) systems play a crucial role in water purification. However, these systems are prone to scaling due to dissolved salts and minerals, which can clog membranes and reduce output. RO antiscalants offer a powerful solution.

How RO Antiscalants Boost Efficiency in Industrial Applications:

• Prevents Membrane Scaling
  Inhibits the precipitation of salts like calcium carbonate, calcium sulfate, barium sulfate, and silica, which can block membrane pores.
• Extends Membrane Life
  Protects the expensive RO membranes from damage and fouling, reducing the frequency of costly replacements.
• Improves Water Recovery Rate
  By keeping membranes clean, antiscalants allow the system to operate at higher recovery rates with minimal downtime.
• Reduces Cleaning Frequency
  Minimizes the need for chemical cleaning (CIP), which saves both chemical cost and labor hours.
• Lowers Energy Consumption
  Clean membranes mean less pressure is required to push water through, reducing pump load and energy costs.
• Ensures Consistent Water Quality
  Maintains the desired output parameters, which is critical in industries with strict water purity requirements (e.g., pharma, electronics).
• Enables High TDS Feed Water Usage
  Allows RO systems to handle high total dissolved solids (TDS) feed water without sacrificing performance.
