Water treatment projects for dishwashing

Consumers of drinking water often complain about white deposits on dishes after using a dishwasher. These deposits indicate the presence of elevated levels of calcium and magnesium ions, or high water hardness in drinking water.

Under high temperatures, calcium and magnesium ions precipitate, forming white deposits (scale) on dishes as well as on pipes. While white deposits on dishes can be removed by rinsing with cold water, deposits that form in pipes significantly affect the efficiency and lifespan of dishwashers. To prevent scale formation on other sanitary equipment and in pipes, the water must be softened.

Another issue that can cause unpleasant stains on dishes and deposits in pipes is elevated iron and manganese concentrations in drinking water. High iron concentrations lead to rust/brown stains and deposits, while elevated manganese content causes black deposits. To address iron and manganese concentrations in drinking water distribution systems, water softening should be combined with filtration systems for iron and manganese removal.

Before selecting the most suitable water treatment solution, we recommend conducting drinking water testing for 19 chemical parameters in our laboratory to accurately identify the water quality issues in your building and provide the best solution for your water treatment needs.
