WATER QUALITY PROBLEM

Water hardness is a set of natural properties of water related to the concentration of calcium and magnesium salts. Although hard water is not harmful to human health, it can pose a serious threat to various appliances, such as washing machines, boilers, dishwashers and pipes, creating precipitation in pipelines and especially on heating elements. Using such water for washing laundry requires more detergent. Water hardness will reduce the quality life of sanitary equipment and increase energy consumption.

SOLUTION

The solution of these problems for households and production needs is softening by WATEX CMS series ion exchange resin filters (reduces limescale) that are regenerated with NaCl. Water softening equipment also effectively reduce iron, manganese and ammonium.

FILTER PERFORMANCE

For recovery of filtration media (ion resins) reagent (NaCl or salt tablets) is used. Wastewaters produced in regeneration processes of equipment in WATEX CMS  can be directly discharged to biological wastewater treatment plant. WATEX CMS consists of a filter column, control valve and salt tank. The filter column is filled with ion exchange resin (cationic), which reduces hardness and iron concentration in water. The control valve performs automatic regeneration. Salt tank is filled with a reagent (NaCl, salt tablets) for resin regeneration. Capacity of filtration media is calculated according to amount of resins and raw water quality.                

FILTER CONTROL

WATEX CMS is equipped with a Clack WSCI1 control valve, with a built-in flow meter that performs filtration media regeneration according to water consumption. Flowmeter saves water and salt used for filter regeneration. The valve can be fitted with a bypass pipeline that allows to perform maintenance works with ease. Control valve saves all information in case of power failure. Equipment has many parameters that can be adjusted according to needs, such as washing time, frequency, reagent consumption, and so on. It is possible to change the water hardness with certain control valve body (additional component). The equipment also performs iron removal function, however the dissolved iron concentration cannot exceed 2.5-3.0 mg/l.

EQUIPMENT MAINTENANCE

Although the equipment uses salt tablets for regeneration it is safe to use filtered water for drinking and other human needs. It is necessary to provide electricity connection power (one socket), sewerage drainage and incoming / outgoing water supply with minimum pressure of 2.5 bar.       

RECOMMENDATIONS:

  • Before selection of equipment, it is recommended to test raw water chemical composition.
  •  Before the water filter, it is preferable to install mechanical filter to ensure long-term equipment service life.        

 Additional equipment options:

  • Condensate isolation for tank
  • By-pass valve – For easier assembly
