Water purification system

A low pressure, high flux water purification system. In a continuous loop recirculation system metal hydroxides are employed to bind impurities in wastewater into particles of a size greater than ten angstroms which are then separated from the water by means of an ultrafiltration membrane.

description A low pressure, high flux water purification system. In a continuous loop recirculation system metal hydroxides are employed to bind impurities in wastewater into particles of a size greater than ten angstroms which are then separated from the water by means of an ultrafiltration membrane. A large metal hydroxide/impurity ratio is maintained thereby permitting a purified water flux of over 30 gfd using filter tubes of diameter greater than 100 mils and length greater than 6 inches under a wastewater pressure as low as 9 psig. The filter tubes are grouped in bundles, each bundle within its own water collecting box, so that system down time is minimized and purification standards may be maintained in the event of a partial failure of the system.
