scale inhibitor

1.       Discontinuation protection

Before the discontinuation of the boiler, replenish the drugs into the boiler and system to make the system water pH more than 10.5. Then close the boiler and system.

2.       Announcements

a.       Because of the different water qualities of the different areas, after the recommended dosage, test the pH of the water in boiler frequently. Adjust the dosage according to the actual situation to keep the pH of the boiler water and system water between 10~12.

b.       Before the operation of the boiler, adjust the initial dosage to ensure the drug concentration of the solution qualified (pH≥10.5). Then operate the boiler or the system.

c.       If the dissolving tank is home-made or is made by remolding the salt pond, sometimes, because of the over-dosing or short stirring time, there will be sediment in the bottom of the dissolving tank. Reduce the concentration of the solution, lengthen the stirring time or add warm water periodically into tank to dissolve the sediment. Otherwise the accumulation of the sediment will damage the dosing pump and then reduce the anticorrosion and descaling effects of the drug.
