It is common to use acids for washing cooling systems. The combination of multi-acids is very effective to remove hard scale and metal oxides caused by corrosion. Use this solution when the system is out of circuit. The equipment should be washed is removed from the entire system and the solution is circulate by a pump in a closed circuit. Working with this solution requires safety and should use masks, gloves and special clothing (see MSDS).
Calibration of Using Mitreh 825 Solution:
In order to scale removing in open circuit cooling tower systems, the amount of solution consumption varies according to the amount of scale available in system, and you need to consult with our company’s technical experts to achieve better performance.
System water analysis and scale formed at the installation, estimation of approximate amount of scale available at the installation, the volume of make-up water during the day, and the kind of alloys in the various parts of the system are required prior the scale removing operation.
