Laundry:
 Water is an integral part of this Industry. The primary water concern for this application is hardness. Dissolved salts of calcium and magnesium usually in the form of bicarbonate salts such as chloride, sulfate or nitrate salts cause hard water.
Water hardness is measured in grains. One grain of calcium bicarbonate equals 17.1 ppm by weight. The American Society of Agricultural Engineer's water hardness classification system has four classes:
Class |
Grains per gallon |
Soft |
0 to 3.5 |
Moderate |
3.5 to 7 |
Hard |
7 to 10.5 |
Very Hard |
more than 10.5 |
Hard water reduces the cleaning efficiency of both soap and detergents. It reacts with soap to form curds and soap scum on fixtures. Furthermore, hard water reacts with detergent in laundry to form solids that precipitate out of solution. These solids collect between the fibers in clothing, making them stiff. These collected solids can not only wear out clothes faster, but also aide in discoloring of clothes. Moreover, hard water solids also collect in washing machines and water heaters, causing excessive wear.
Solutions
So~Safe Water Technologies provides comprehensive solutions to meet the demanding needs of this industry. So~Safe Water Softeners are used to treat hard water. They ensure that the water coming in to the washing machines is purified and softer in nature. This not only increases the efficiency of the detergent, but also keeps the fabric soft and long lasting.
