Reasons for adding antiscalants to RO systems?

Adding antiscalants to RO systems because modern reverse osmosis systems use membranes to produce high-quality water. Ensure that the peels do not affect the membranes and prevent contamination. It is necessary to use a good quality anti-scalant. Due to the high pressure effect, water will pass through the membranes leaving behind minerals that will not pass due to their ionic size and additional deposit formation will occur if allowed to concentrate beyond the saturation limit. Deposits on the surface of the membrane prevent water from passing through. Therefore, it is necessary to prevent these deposits, known as calcification, resulting from water treatment with RO systems to continue their continuous operation.

If the wrong antiscalant is used, it will allow scaling and subsequent loss of performance, so injecting the right antiscaler at the correct dosing rate is important to completely prevent scaling problems.

Therefore, you must make sure to use the appropriate type of antiscalant for your reverse osmosis plant. This can be determined based on a number of factors, the most important of which is the quality of the source water that will be treated.

Application areas of antiscalant for RO reverse osmosis systems

Antiscalants are fed upstream of the RO system and usually require a very low dose rate and at the same time maintaining a proper antiscalant dosing rate is very important. On the one hand, underdosing can lead to scaling or fouling, and on the other hand, overdosing can cause anti-scalant to be deposited on the membrane surface creating a fouling problem.

In this article, you will find how to calculate the amount of antiscale added to reverse osmosis systems

Why should antiscale be added to reverse osmosis systems?

Because RO produces the highest water purity of all water technologies known to man, the cleanliness rate is nearly 100%.

The reverse osmosis membrane is the main part of the reverse osmosis system. As the system continues to operate for a long time, the calcium and magnesium plasma in the water will continue to precipitate and adhere to the surface of the reverse osmosis membrane. The formation of deposits or calcification leads to blocking the pores of the membrane. This will affect the water efficiency of the reverse osmosis system, and lead to damage to the reverse osmosis membrane.

Since the reverse osmosis membrane is more expensive, in the operation of the system, a dosing system is added. Water treatment machine in water with anti-scalant for reverse osmosis systems to retard the precipitation of calcium and magnesium ions and fouling of the membrane surface.

The reverse osmosis preventer is specially used for reverse osmosis (RO) system, nanofiltration (NF) and ultrafiltration (UF) system. It can prevent membrane surface pollution, can improve water production and water quality, and reduce operating costs.

Advantages of using antiscalants for reverse osmosis systems

• Effective control of inorganic pollution in a wide concentration range.
• It does not combine with iron and aluminum oxides and silicon compounds to form insoluble substances.
• Effectively prevents silicon aggregation and deposition, and the concentration of SiO2 on the concentrated water side can reach 290 ppm.
• It can be used in CA and TFC reverse osmosis membranes, nanofiltration membranes, and ultrafiltration membranes.
• Excellent solubility and stability.
• Effective in the feed water pH range of 5 to 10.
