The PENTEK U440 Ultra-filtration System provides complete point-of-entry filtration proven to reduce turbidity, particulates and cysts for safer, cleaner water at every tap. The system employs hollow fiber ultra-filtration membrane technology to filter impurities as small as 0.025 microns.
To maximize membrane capacity and service life, a metered flushing cycle is controlled using an advanced controller and high-performance turbine meter. The self-cleaning forward and backflush cycle are initiated when the programmed capacity of the membrane is reached. During the backwash, flow is reversed and particles are ejected from the pores of the membrane and flushed to drain. In the forward flush cycle, service water passes through the capillaries at a high speed, scouring particles from the membrane surface and rinsing them from the system. Since power is only required to flush the system, outages and interruptions will not jeopardize the integrity of membrane or its ability to provide clean, safe water.
The advanced electronic controller provides a programmable day override which allows the unit to flush every day with fresh water when the system is not in use. Critical system diagnostics, including totalized flow, instantaneous flow rate, and previous days water usage, are available to optimize flushing cycles and monitor performance. |
