Product treats difficult scales
Fluid Dynamics International, a U.K.-based manufacturer of hard water scale prevention systems, has launched MagCAT, a product of almost 40 years’ experience in treating difficult scales such as those from water containing high levels of sulphate, silica or phosphate and where oil contamination is present.
MagCAT uses powerful magnets that are encased in poleheads manufactured out of the same metal that is used for the catalytic core of Fluid Dynamics’ Colloid-A-Tron. The calcium carbonate particles which are formed when hard water is heated remain in suspension after this magnetic treatment instead of precipitating as scale on pipework and heat transfer surfaces. It also gradually removes existing scale.
Alier Paper, a Spanish paper mill, was adding 3 tons per day of carbon dioxide to its water system to prevent scaling of their vacuum pumps but with limited success. In January 2010 the company installed a 150-mm-diameter MagCAT in the feed line to its vacuum pumps. The cautious chief engineer reduced the carbon dioxide injection slowly over a three-month period, and the vacuum pumps now operate with no treatment other than the MagCAT. The savings in carbon dioxide paid back the capital cost of the MagCAT in just five months, according to Fluid Dynamics.
The MagCat uses no power, has no consumable parts, requires no maintenance and aims to be very simple to install.
