We all know that when using antiscalants in reverse osmosis equipment, many issues need to be constantly addressed to ensure the high-quality performance of the reverse osmosis equipment.

First, it is necessary to confirm that the flocculant and antiscalant used are compatible; otherwise, it will cause the reverse osmosis membrane to become blocked. When using reverse osmosis equipment antiscalants, adding too much or too little is not suitable; both will lead to reverse osmosis membrane pollution. Therefore, it is essential to add the antiscalant reasonably.

The antiscalant used in reverse osmosis equipment is part of the pretreatment of the reverse osmosis equipment. The antiscalant mainly converts high-concentration water into low-concentration water quality, effectively removing substances that easily form scale and large particulate impurities in the water quality, thereby achieving the water quality standards of the reverse osmosis equipment's feed water and making it less likely for the reverse osmosis membrane to scale. Characteristics of reverse osmosis antiscalants: Effectively control inorganic scaling. Effectively inhibit silicon precipitation. Easy to dissolve and has good stability. Does not form insoluble substances with iron and aluminum oxides.

The antiscalant is usually added using a dedicated chemical dosing tank, adding it to the raw water at regular intervals. The antiscalant injection point is generally before the filter. The dosage mainly depends on the flow rate of the reverse osmosis equipment, whether it is proportional. Reverse osmosis antiscalants can effectively reduce the pressure of the reverse osmosis equipment. If the impurities in the raw water are not treated with an antiscalant, the reverse osmosis membrane is very prone to scaling, which will not only affect the normal operation of the reverse osmosis equipment but also affect the service life of the reverse osmosis membrane.
