POST TREATMENT:
ENDOTOXIN FILTERS

      * Endotoxin Filters, or ultra filters, are used to trap bacteria and bacterial endotoxins.

      * Endotoxin Filters are the final purification device before the water goes to the treatment floor.

      * Endotoxin Filters are required downstream of UV Lights and DI Tanks.

      * The Delta (Δ) Pressure (prefilter in - [minus] postfilter out) is checked daily and recorded in the
         Daily Water Quality Monitoring Log. If the delta pressure is greater than 20 contact B.E.S.T.
