Ultrafiltration systems Dulcoclean® UF

Ultrafiltration systems Dulcoclean® UF

Dulcoclean® UF systems are suitable for removing high turbidity peaks, particles and microbiological impurities (bacteria, viruses, parasites). Even with temporary or microbiological contamination after heavy precipitation the systems provide a constant filtrate quality – free of turbidity and pathogens.

The extremely robust hollow fiber membranes are operated in the economical dead-end process, thus reducing water and energy consumption to a minimum.
A PLC guarantees fully automatic operation of the filtration system. The parameters are entered user-friendly via a touch panel. A variety of control options ensures the highest possible degree of flexibility and operational reliability. Adapted to the untreated water quality, chemicals can be optimally added to support the cleaning process. All relevant operating parameters are registered electronically.

 

Advantages

  • Removal of turbidity with constant filtrate quality independent from fluctuations in the raw water quality
  • Very high bacteria and virus (referred to MS2 phages) retention rates of 99.999 % and 99.99 % respectively
  • Minimum energy and water consumption thanks to economical dead-end operation
  • Maximum operational safety and reliability ensured by fully automatic system control with integrated pre- and post-treatment
  • Compact design ensures convenient installation in existing systems control room or in a container
  • Optional: Complete solutions with precisely matched pre- and post-treatment as well as waste water treatment

Features

  • PLC for user-friendly operating with touch panel. Monitoring and data logging of all relevant operating parameters
  • Constant filtrate output and efficient backwash ensured by speed-controlled filtration and backwash pumps
  • Robust PES membrane in PVC housing with DVGW recommendation
  • Variable cleaning concept for optimum adaptation to changing feed water quality
  • Integrity-test for highest possible drinking water quality

Main applications

  • Drinking water production from surface water, spring or well water
    Water quality improvement in the food and beverage industry
    Pre-treatment for downstream desalination plants (RO, NF or ion exchanger),
    e.g. sea and brakish water desalination
