• Amiad Filtration Systems provides efficient solution to central Florida city's water needs.

ST. CLOUD, FL, Feb. 7, 2007 -- Amiad Filtration Systems filter products were selected and installed for the expanded 20.25 MGD water reuse system at the City of St. Cloud's Michigan Avenue wastewater treatment plant. The self-cleaning-automatic system utilizes six Model EBS-10,000 units with a filtration degree of 200 microns. The cleaning mechanism consists of a suction scanner "focus back-flush" technology; which takes advantage of simple physics for cleaning (see Figure 1). The decision for using Amiad Filtration Systems was based on the experience of a smaller and successfully operating system previously installed in October 2003.

The "focus flush" concept in Figure 1 that Amiad uses specifically exhibits 100% cleaning using the suction scanner technology. The cleaning nozzle is designed within close tolerances to cylindrical screen for high efficiency of back-flushing.

During a bdack-flush cycle, water moves both tangentially and directly into the orifice of the nozzle due to the large difference between operating and atmospheric pressures.

Expanding this concept further (see Figure 2); the high velocity (50ft/sec²) combined with the spiral movement of the nozzle(s) across every square inch of screen area effectively removes the entire filter cake without any interruption of flow through the filter units. Typically, back-flushing wastewater is less than 1% of total flow.

The simplicity of design, cleaning efficiency, and reliability based on just a few moving parts are the attributes of a low operating and maintenance system favorable for municipal and industrial applications.

The actual installation was commissioned in September 2006 on Michigan Avenue in the city of St. Cloud, FL.
