Lime scale or other salts are found in almost all water in dissolved forms. Depending on the amount of calcium carbonate, dissolved carbonic acid and the temperature of the water, the minerals start to crystallize and start depositing on surface areas. This phenomenon can cause substantial problems for technical applications.

The deposits reduce heat transfer in heat exchangers and lower the efficiency of the heating installation or cooling system significantly. Increasing pressure losses and decreasing flow rates are other symptoms associated with the same problem. In many cases the water is treated chemically to avoid these problems. The Merus water treatment however provides an environment-friendly solution.

The Merus technology avoids or slows down the build-up of lime scale, rust, biofilm, salts and paraffin wax.
