Ultrafilter UF-400 Defender

The ultrafilter water purification system is a stand-alone system that consistently provides clean, filtered water for laboratory water applications.  The system can be applied universally to any Edstrom automated watering system and used as a standalone unit or as a prefilter for a reverse osmosis system.  When used before a reverse osmosis system, the ultrafilter helps increase membrane life.

The Ultrafilter water purification system removes bacteria and viruses from water.  The system is self-flushing, greatly reducing ongoing maintenance cost.  In operation, the system uses electricity to conduct the flushing but can safely run for several days without power (provided there is water pressure) while still supplying filtered water.  For this reason, the ultrafilter is often employed in a facility's emergency contingency plan.  By specifying a selectable bypass, the ultrafilter can circumvent the reverse osmosis unit during an emergency.

Ultrafiltration provides a level of purification between particles filtration and reverse osmosis, removing viruses and bacteria while leaving in most minerals.  For a great level of purity, reverse osmosis will be required.  In those applications, an ultrafilter can be used to protect the RO membrane, increase RO efficiency and reduce cost.
