Fouling of the reverse osmosis membrane will reduce system performance and lead to the need for early replacement of the reverse osmosis membrane. Dirt and sediment accumulated on the reverse osmosis membrane will cause problems such as deterioration of permeability performance, reduced permeability, unplanned downtime, increased water consumption, and increased energy consumption.

◇Regulatory status
This product has obtained the international certification of the reverse osmosis antiscalant category in the /standard. Its official name is other water supply products. The maximum dosage is/. Only products with the / logo on the packaging can be used for drinking water treatment.
◇Product Dosing
The preferred solution is to use a closed dosing system to add pure products to avoid contamination by external impurities. A closed feeding system means that the fluid flows directly from a closed storage container into the processing medium without being exposed to the atmosphere but the usual exhaust or pressure safety devices are still open to the atmosphere.
Continuous dosing is necessary to greatly reduce scaling and dirt precipitation in the reverse osmosis membrane. It is recommended to use a dosing pump with the highest stroke frequency for feeding and adjust the dosage by adjusting the stroke of the pump to effectively protect the film system.
◇Dosage requirements
The recommended dosage based on the operating value and temperature is that an antiscalant product needs to be added for every silicon in the incoming water. When the concentrated aqueous salt solution contains a high silicon content, it is necessary to ensure that the proper dosage is maintained in the feed water (in the concentrated water). Because the silicon scale on the membrane is particularly difficult to clean.
Silica scaling is difficult to predict because both dissolved and colloidal silica may be present and the nature of the chemical reactions is complex. Preventing the formation of matrix materials such as insoluble calcium and iron salts is critical to preventing silicon scaling. It is also critical to use efficient automatic permeate water flushing facilities to treat water with high silica content. These facilities will use permeate water to flush incoming water containing supersaturated salts and treatment chemicals before shutting down the system.
The dosage depends on the chemical properties of the feed water, membrane type and system operating parameters (such as recovery rate, temperature and pressure, etc.). These parameters determine the fouling species that may cause membrane module fouling. It is recommended to use special antiscalant calculation software to select the optimal dosage. This software can select the appropriate antiscalant and calculate the appropriate dosage based on the design and operation of the r system and the chemical characteristics of the inlet and concentrated water ends. The software is easy to use and automatically calculates various results.
◇Storage
