How do you deal with scaling in circulating water?
Control drainage to reduce the concentration ratio, thereby making the overall water quality more corrosive; observe the operational effects and conduct regular inspections. Avoid excessive corrosion caused by chemical cleaning
Are there any with scale and corrosion inhibitors (NaPO4)?
A new patented descaling and anti-scaling product that generates no electricity or magnetism and requires no additives – worth taking a look at
Perform regular chemical cleaning; don’t believe in those nonsense static electricity techniques – it’s garbage
Use softened water, along with corrosion inhibitors and scale inhibitors, to reduce the concentration ratio
Chemical cleaning: After delivery, for the tube side, high-pressure cleaning can be used; for the shell side, it can be soaked in weak acids such as citric acid, then the solution is drained after circulation； During operation, forced circulation can be achieved by adding pumps, and organic acids can be used for cyclic descaling ； For daily management, this involves considering the use of softened water, or reducing the concentration ratio, increasing the frequency of backwashing the bypass filters, and adding scale inhibitors
1. Analyze the cause of scaling: Is the hardness of the make-up water too high? Is the system concentration multiplication factor set too high? Are the actual process operation parameters stringent? Design flaw in the equipment itself (insufficient flow rate)? 2. Treat the symptoms: Rehydrate: Water can be treated by softening it, for example by adding sodium carbonate, sodium bicarbonate, etc ； Concentration ratio: Control the system concentration; it is recommended to refer to LSI or RSI values ； Other factors: Handle according to the actual situation ； I have over 6 years of experience in recycled water treatment research; feel free to reach out if you have any questions ；
When there are few chemical gases in the air, electromagnetic descaling can be used, with excellent results; it reduces the amount of water that needs to be added, eliminates the need to purchase chemical reagents, and is beneficial to the environment
