Seeking help with circulating water treatment
Thread Content
The current concentration ratio of our circulating water is above 3.5； The turbidity is within acceptable limits; total phosphorus is either above the limit or just meets the standard; hardness is extremely high. How should it be handled?
Professional water treatment personnel should be hired for the treatment and routine maintenance. Reduce water hardness through ion exchange or membrane methods.
What is the specific hardness? Our circulating water hardness is 1100 mg/l
Our circulating water level above 600 is considered excessive

Ladies and gentlemen, the ultimate goal of circulating water system management is to keep the corrosion rate and scaling rate at **standard levels**. There’s no need to focus too much on process control; we use a new type of chemical that maintains the pH above 7, without controlling any other parameters, thus enabling zero wastewater discharge from the circulating water system.
The inlet water hardness of 600, along with a concentration factor of 3.5, is too high.
The inlet water hardness is 600, so what about the calcium hardness of the inlet water? What about total alkalinity? Under normal circumstances, the control criteria are generally based on the calcium hardness and total alkalinity of the circulating water. At natural pH, if it is necessary to maintain a concentration ratio of over 3.5, it is recommended that the calcium hardness and total alkalinity of the feed water not exceed 400 ppm. Of course, if it is operated with acid, the situation will be different; it depends on the specific circumstances.
