General guidelines for antiscalant application and dosing

A well-designed reverse osmosis system produces high-quality purified water.

However, it relies on more than quality equipment alone. Effective pretreatment, chemical dosing and ongoing monitoring are essential.

At G-Chem Aquacare, we provide specialised reverse osmosis treatment solutions. These solutions are designed to improve membrane performance, minimise fouling and extend membrane life.

Our programmes support every stage of the reverse osmosis water treatment process. The result? You maintain consistent water quality while improving operational reliability.

How We Use Antiscalants

Antiscalants are typically dosed upstream of the reverse osmosis unit to ensure adequate mixing before water reaches the membranes. Effective chemical treatment helps control scale formation and improve membrane efficiency.

Our programmes include:

  • Antiscalant dosing and optimisation
  • Membrane protection strategies
  • Pretreatment system monitoring
  • Fouling prevention
  • Water quality analysis
  • System performance evaluations
  • Technical support and troubleshooting

What Is Reverse Osmosis?

Reverse osmosis (RO) is a water purification process that uses a specialised membrane to remove dissolved salts, minerals and other impurities from water. The result is high-quality purified water suitable for a wide range of industrial and commercial applications.

To perform efficiently, a reverse osmosis system requires proper pretreatment and membrane protection. Without the right treatment programme, membranes can become blocked by scale, fouling and biological growth, reducing performance and increasing maintenance costs.

Our goal is simple: to keep your reverse osmosis system operating efficiently, maximise membrane life and minimise downtime.

MaxiFLOW Series:

The MaxiFLOW range has been specifically developed to support the performance of reverse osmosis systems by controlling scale formation and protecting membrane surfaces.

MaxiFLOW 100
A general-purpose antiscalant designed for reverse osmosis water filtration systems. MaxiFLOW 100 is highly effective in controlling calcium carbonate, calcium sulphate, barium sulphate, strontium sulphate and calcium fluoride scale formation.

MaxiFLOW 135
A severe-service inorganic scale inhibitor designed for challenging operating conditions. The product effectively controls a wide range of scale deposits and supports long-term membrane performance.

MaxiFLOW 260
A premium-performance antiscalant developed for applications where iron and silica control are critical. In addition to controlling common inorganic scale deposits, MaxiFLOW 260 assists in maintaining optimal membrane efficiency under demanding conditions.

RO-Kleen Series:

The RO-Kleen range consists of specialised membrane cleaning liquids and powders designed to remove deposits and fouling from reverse osmosis membranes.

Regular membrane cleaning forms an important part of any reverse osmosis treatment programme, helping to:

  • Restore membrane performance
  • Improve water production rates
  • Extend membrane lifespan
  • Reduce operating costs
  • Improve overall system efficiency

Combined with effective pretreatment and antiscalant programmes, RO-Kleen products help maintain the long-term performance of commercial water treatment systems and industrial water purification systems.

Frequently Asked Questions

A reverse osmosis system uses pressure and specialised membranes to remove dissolved salts and other impurities from water. It produces high-quality purified water for industrial, commercial and potable water applications.

Antiscalants help prevent scale from forming on membrane surfaces. This improves system efficiency, extends membrane life and reduces maintenance costs.

This depends on water quality, operating conditions and system performance. Regular monitoring helps determine when cleaning is needed.

Fouling can be caused by scale, suspended solids, biological growth and other contaminants. Proper pretreatment and routine maintenance help reduce these problems.

We supply antiscalants, membrane cleaning products and technical support to help improve efficiencies, protect membranes and keep reverse osmosis systems operating at their best.
