ALEXAPURE FILTER MICROBIOLOGICAL P231 TEST REPORT
Report # 15-288 (Alexapure Filter Element) Report Date: 10/27/2015
Customer Name: Alexapure, LLC
EXECUTIVE SUMMARY
The Alexapure Filter Element was tested for Microbiological Reduction following the NSF protocol P231 for a total volume of 200 gallons. The Alexapure Filter element qualifies as a microbiological water purifier set forth by the NSF protocol P231 for 200 gallons.
INTRODUCTION
The Alexapure Filter Element was tested for Microbiological Reduction following the NSF protocol P231 for a total volume of 200 gallons. The filter element was challenged with tap water adjusted and spiked with Bacteria (Klebsiella); Virus (Rotavirus); and Polystyrene Microspheres (Cryptosporidium, Giardia lamblia) and tested using Standard Methods for the Examination of Water. The Alexapure filter element qualifies as a microbiological water purifier set forth by the NSF protocol P231 for 200 gallons.
REAGENTS, MATERIALS, AND LAB EQUIPMENT
Barnstead Lab-Line Incubator Klebsiella pneumoniae (Bacteria) Rotavirus (Virus)
Polystyrene Microsphere (Giardia lamblia, Cryptosporidium).
Sterile water, Phosphate buffer, fluorescein isothiocyanate dye (FITC), 0.45 µm membrane filters. Amscope EPI Fluorescence Microscope FM-320TA-3M.
Alexapure Filter Element.
PROCEDURE
Flushed the filter element with approximately 1 gallon of sterile water. Prepared 20 gallons of general test water daily for 6 consecutive days with Klebsiella at a concentration of 108/L, Rotavirus at 107/L, and microspheres at 106/L. Two days of stagnation. Prepared 20 gallons of challenge water for the following 4 days without adding the micro-organisms and two additional days of stagnation. Table 1 and 2 summarize the general test and challenge water properties. Passed 20 gallons of the general test water through the filter element per day, every day for the first 6 days. Collected the effluent water and analyzed the filtered water for micro-organisms following the Standard Methods of Analysis of Water 21st Edition, methods SM 9222-D (bacteria); SM 9510-B (virus); SM9711-B (cyst). Left the filter system in stagnation for the following 2 days, then added 20 gallons per day of the challenge water and analyzed the filtered water for micro-organisms following the Standard Methods of Analysis of Water 21st Edition, methods SM 9222-D (bacteria); SM 9510-B (virus); SM9711-B (cyst). The results are summarized in Table 3, 4, and 5 below.

EXECUTIVE SUMMARY
One Filter Element was tested for Microbiological Reduction for a total volume of 10 gallons. The filter element qualifies as a microbiological water purifier.
INTRODUCTION
One Filter Element was tested for Microbiological Reduction for a total volume of 10 gallons. The filter element was challenged with tap water adjusted and spiked with e. Coli Bacteria and tested using Standard Methods for the Examination of Water. The filter element qualifies as a microbiological water purifier.
REAGENTS, MATERIALS, AND LAB EQUIPMENT
Barnstead Lab-Line Incubator
e. Coli Bacteria NSI Catalog # 9001H Lot 052215. Sterile water, Phosphate buffer
Alexapure Gravity Block Filter Element.
PROCEDURE
Flushed the filter element with approximately 1 gallon of sterile water. Prepared 10 gallons of challenge influent water with e. Coli Bacteria at a concentration of 108/L. Table 1 summarizes the Influent water properties. Passed 10 gallons of Influent water through the filter element. Collected the effluent water and analyzed the filtered water every 5 gallons for micro-organisms following the Standard Methods of Analysis of Water 21st Edition, methods SM 9222-D (bacteria); The results are summarized in Table 2 below.
