Title 22 Pilot Testing

GDisk® DuraPile™ 10, 5, and 2 µm Cloth Media

Continued excellent results have come from Title 22 pilot testing of Beacon’s GDisk® DuraPile™ cloth medias at the Meridian Idaho Water Reclamation Facility.  Testing protocol required data to be collected before and after our GDisk® XS pilot filter with our 10- and 5-micron filtration rating cloths.

Facility secondary effluent was pumped to our filter at multiple hydraulic loadings. During the workday, influent was also spiked with return activated sludge to increase the solids loading to our pilot filter.  Collected data implies that our 10- and 5-micron filtration rating cloths meet all relevant California Title 22 requirements, including less than 2 NTU average within a 24-hour period.  Beacon fully expects that the final written report will recommend Title 22 approval of our 10-, 5-, and also our 2-micron cloth, which performed even better during bench scale testing.

Testing Results

10 Micron Testing Results Graph
10 micron Beacon GDisk® DuraPile™ NLB10 with influent at 3 gpm/ft2 Solids were spiked to provide an average influent turbidity of 3.3 NTU and effluent averages 0.83 NTU.
Filter cloth testing result graph
Influent was spiked again to produce an increased solids loading that resulted in 5.2 NTU average and hydraulic loading rate was maintained at 3 gpm/ft2.
Graph with pilot testing results
Influent was spiked to produce an increased solids loading that resulted in 9.8 NTU average and hydraulic loading rate was maintained at 3 gpm/ft2. The effluent averages 1 NTU.
Pilot Testing Results
Hydraulic loading increased to 6 gpm/ft2. Influent was also spiked to produce an increased solids loading that resulted in 5.2 NTU average and the effluent averages 0.87 NTU.
Pilot testing results (graph)
Influent was spiked to produce an increased solids loading that resulted in 10.2 NTU average. Hydraulic loading rate was maintained at an elevated 6 gpm/ft2. The effluent averages 1 NTU.
Pilot Testing Results (Graph) for 10 micron cloth
10 micron DuraPile™ NLB10 cloth: Hydraulic loading rate was increased to 10 gpm/ft2 and influent spiked to produce a solids loading that resulted in 5.2 NTU average and effluent averages less than 1 NTU.
Pilot Testing Results Graph for 5 micron cloth
5 micron Beacon GDisk® DuraPile™ FineLB5 cloth media: Influent was spiked to produce an increased solids loading that resulted over 5 NTU average. Hydraulic loading was maintained at a 3 gpm/ft2 rate. The effluent averages 0.9 NTU.
Pilot Testing Results (Graph) for 5 micron cloth
Hydraulic loading rate was increased to 6 gpm/ft2. Influent was spiked to produce an increased solids loading that resulted in almost 5 NTU average and the effluent averages less than 1 NTU.
5 micron Pilot Testing Results (Graph)
Hydraulic loading rate was increased to 10 gpm/ft2 and influent spiked to produce a solids loading that resulted in 3 NTU average. The effluent averages 0.89 NTU utilizing the FineLB5 cloth.
Pilot Testing for FineLB5 cloth
Shows a continuance of data recorded that afternoon without solids spiking at 10 gpm/ft2.

Both the Beacon GDisk® DuraPile™ 10-micron NLB10 and the 5-micron FineLB5 cloth medias performed extremely well during the pilot test periods.  These and other results show that these DuraPile™ cloths meet all relevant Title 22 requirements, despite challenging elevated hydraulic and solids loading rates. Stay tuned for the publication of the formal Title 22 report in the very near future!
