Description
Seawater desalination in MED and MSF systems has always been associated with the formation of scale layers in the system due to the concentrating of residual water in the system of solutes and scale compounds. Scales created on pipes and surfaces by creating an insulating layer will greatly prevent heat transfer. Acids are commonly used to remove scales formed in these systems. Mineral Acid-based Mitreh 833 solution separates large amounts of formed scales from the walls and removes them from the system.
Calibration of Using Mitreh 833 Solution:
In order to remove the scale in the multi-stage desalination, the dosage of solution consumption varies depending on the volume and type of scale. It needs to be consulted with the company’s technical experts for scale removing.
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.
