What is antiscalant

Antiscalant (Ultraside) are anti-sediment substances that are injected into RO desalination systems to clean water purification systems and to prevent the formation of industrial membrane deposits.

Raw water contains mineral salts and salts, which are deposited on the membrane while passing through the membrane, and these deposits gradually clog the pores of the membrane, which reduces the efficiency of the water coming out of the RO desalination system.

Antiscalant is a solution that is used to reduce the effects of deposits such as calcium carbonate (CaCO₃), calcium sulfate (CaSO₄), barium sulfate (BaSO₄) and strontium sulfate (SrSO₄) that are formed on the polyamide membrane or the membrane of the desalination device. is used The possibility of formation of silica deposits (Sio2) is lower than other deposits.

Types of anti-scalant

Currently, there are various types of antiscalants available in the market, which can be prepared and used according to the :operating conditions of the industrial water treatment system. In general, antiscalants can be divided into the following two ways

Phosphate base: Phosphate base consists of compounds of carboxylic acid and phosphate group, and this type of anti-fouling can be considered as the best quality product in the market. Phosphate-based antifouling has an excellent effect and acceptable performance in reverse osmosis devices, and among the industrial products in this category, A104 and A111 can be mentioned.

Polymer base: Polymer-based antiscalant is used in cases where sea water or very salty waters are desired, and this type of antiscalant has a high power in case of carbonated and sulfated sediments. In the type of polymer base, the molecular weight is high, and one of its important advantages is the possibility of using it in different areas and the possibility of preventing biological pollutants.

Application of antiscalant in all kinds of devices

Reverse osmosis water purification devices (as a descaling solution)

Industrial and semi-industrial desalination device

Sea water desalination device

cooling towers
