SCALE PROBLEMS REMOVED AT DAIRY
January 1st 2004

Tims Dairy has saved on chemicals, time and lost production since installing Hydropaths Hydroflow units at its Chalfont St Peter factory to prevent limescale build up as well as milk scale build-up on the plate pack (heat exchanger). Hydroflow physical water conditioning units were installed in three locations to control limescale from the water feeds, and one before the heat exchanger on a milk line. Prior to installation of the C45 unit on the milk line, operators had to shut down the line twice a week and clean it with phosphoric acid. Now, cleaning is only required once a week with half the amount of acid. Hydroflow emits randomly-varying electric fields throughout the system. This enhances the precipitation of the bicarbonates from solution to suspension by introducing clusters of ions in the water to act as seed for suspended crystallisation. The resulting suspension, therefore, does not adhere to pipework or internal surfaces, but is merely washed away with the flow and during blow down. Easily fitted to existing and new systems, the unit has low operating costs, giving a short payback time. Fuel requirements are also said to be lower.
