Pre-filter, backflow preventer, duplex water softener, limitron hardness control device, and reverse osmosis unit are all included in the ready-to-connect combi unit. It has a small rotary vane pump and is used to desalinate water with a salinity of up to 1,000 mg/l. With fixed, factory-set limit values and no operation data logging, the RO 524 controller enables entirely automatic operation.
Terms and Conditions: 

  • This device can only be used to desalinate surface or well water that has been properly treated or feed water that meets drinking water quality standards. 
  • The device is meant to operate at 15 °C and 1,000 mg/l of salinity (TDS). 
  • Even after three years of operation, the anticipated permeate yield is reached under these circumstances. 
  • Pre-treatment and raw water quality both affect the permeate yield.

Utilization of  Reverse Osmosis Units With Duplex Softener

  1. Constant desalination and softening of water
  2. Ideal for business and industrial uses when parametrization and operating data tracking are not necessary.

Advantages of  Reverse Osmosis Units With Duplex Softener

  1. Fully integrated pre-treatment that is immediately compatible with the drinking water network
  2. ongoing due to the dual-purpose softener
  3. Just four connecting points—drinking water, permeate, waste water, and socket—make for an easy installation on site.
  4. Economical, factory-programmed RO 524 controller
