Issues regarding the circulating water network
Thread Content
The quality of the circulating water does not meet the standards, and scaling is severe inside the water coolers. How should this be addressed?
Either add chemicals or use electric descaling
Soften first, then enter the circulation system. Descaling agent is added to the circulation water tank for continuous descaling.
Manage it from two aspects: 1. The circulating water system must ensure that the water quality meets the design requirements; 2. Users should also pay attention. 1) The water volume must not be too small, and the temperature difference between the inlet and outlet must not exceed 10°C ； 2) When adjusting the water flow in the heat exchanger, all the inlet valves must be opened, and the flow rate should be controlled via the outlet to ensure the appropriate flow speed of the cooling water.
When the water quality cannot be changed, install a filter before the heat exchanger and clean it regularly
I would like to ask about adjusting the water flow. By reducing the inlet flow, isn’t that equivalent to throttling? The pressure decreases, so the flow rate should increase, right?
The key is to find the cause of the abnormal water quality: was too little scale inhibitor added, and are there restrictions on daily wastewater discharge? If it’s possible to remove the heat exchanger, clean it
