How to ensure the stable operation of reverse osmosis integrated seawater desalination equipment? Author: reverse osmosis desalination equipment integration is a relatively common desalination plants to solve the problem is a lack of fresh water in many regions, the integration of reverse osmosis desalination equipment operation instability happens when practical, small below Let me introduce how to ensure the stable operation of reverse osmosis integrated seawater desalination equipment. 1. Seawater pretreatment: Whether it is seawater desalination or brackish water desalination, feedwater pretreatment is the key to ensuring the long-term stable operation of the reverse osmosis system. 2. Seawater sterilization and algae killing: In seawater desalination projects abroad, chemical reagents such as liquid chlorine, NaCl and CuSO4 are often used to sterilize and kill algae. 3. Coagulation filtration: Coagulation filtration aims to remove colloids and suspended impurities in seawater and reduce turbidity. 4. Reverse osmosis seawater desalination: seawater has high salt content, high hardness, and is corrosive to equipment, and the water temperature changes seasonally. This makes the reverse osmosis desalination system much more complicated than the conventional brackish water desalination system. Investment and energy consumption are also much higher. 5. Chemical adjustment treatment: In order to prevent the production of insoluble inorganic salts, such as CaCO3 and CaSO4, due to the concentration of seawater during the desalination process, scaling and precipitation on the surface of the reverse osmosis membrane and system pipes, the seawater before entering the reverse osmosis desalination system To add anti-scaling agent. 6. Removal of organic matter and peculiar smell in seawater: Seawater is greatly affected by the surrounding environment, and the chemical oxygen demand (COD) of seawater is 1.7~2.5mg/L, especially in summer and autumn, sometimes the seawater has a big peculiar smell Peculiar smell. The above is the introduction of the editor on how to ensure the stable operation of the integrated reverse osmosis desalination equipment. I hope that through the above content, everyone can operate in accordance with the above methods during use, and can effectively protect the integrated desalination equipment.
