✦ Synopsis

Experiments were carried out on spiral would ultrafiltration unit regeneration using various hydraulic washing techniques, for example reduced pressure and large flow washing, static load and immersing, back washing, and static load and immersing combined with back washing. The results show that the unit's stable performance could be maintained by back washing once an hour for feed water with FIs, and the flux restored completely by immersing the unit in pure water for at least 10 h and back washing for 2 min.
