Testing Overview and Performance <br /> NSF Standard 40 NSF Standard 245 <br /> This standard determines whether NSF This standard includes Total Nitrogen NSF <br /> treatment systems product secondary reduction requirements with Class I <br /> treatment effluent quality,with Class I systems achieving a 30-day average <br /> Certified w NSF/ANSI Standard 40 Certified to NSF/ANSI Standard 245 <br /> systems achieving a 30-day average et- effluent quality of more than 50%Total <br /> fluent quality of 25 mg/L CBODS and 30 mg/L TSS or less, Nitrogen removal,25 mg/L CBODS and 30 mg/L TSS or <br /> and pH 6.0-9.0.Testing and certification are done at an less,and PH 6.0-9.0.Testing and certification are done at <br /> independent third party testing facility. an independent third party testing facility. <br /> SETUP:Gravity GSF system with 6"of ASTM C33 sand in SETUP:Gravity GSF system in a bed configuration with 18" <br /> a bed configuration.450 gal/day,(2.0 gal/ftz loading rate). of ASTM C33 sand, 12"of sand/woodchip mixture,and 2" <br /> RESULTS:The Eljen GSF is Tested and Certified by NSF to of limestone.450 gal/day(2.0 gal/ft2 loading rate). <br /> NSF Standard 40 Class 1 since 2014. RESULTS:Tested and Certified by NSF to NSF Standard 245 <br /> More information can be found at www.NSF.org. Class 1 since 2018. <br /> More information can be found at www.NSF.org. <br /> The third-party testing results listed below were taken over a 12 month consecutive period.This extended sampling period <br /> provided verification to the stability and consistency of the Eljen GSF's performance and capability to handle colder weather <br /> conditions.A summary of the test results from the independent third-party evaluation are listed below: <br /> Eljen GSF A42 Modules Treatment Performance during third parry 12 months testing <br /> (includes 12 consecutive weeks with influent temperature below 501 F) <br /> CBOD(mg/L) TSS(mg/L) Fecal Coliform(MPN/100ml) <br /> Average 2.0 2.7 66'` <br /> Average(cold water period) 1.2 1.7 13" <br /> Median 1.0 2.5 71 <br /> Min Value 1.0 2.5 2' <br /> Max Value 7.2 7.0 10 965" <br /> 'Geometric average <br /> Eljen GSF-A42 Influent and Effluent Temperature (degree F) <br /> Influent Temperature Effluent Temperature <br /> 75 <br /> 72 12 weeks with Influent <br /> Temperature below 50'F <br /> 68 <br /> LL <br /> N <br /> L <br /> 61 <br /> m <br /> L <br /> Q 57 <br /> H 54 <br /> y 50 <br /> .a <br /> m <br /> 3 46 <br /> N <br /> «r <br /> 43 <br /> 39 <br /> 36 <br /> 32 <br /> Ory 0� �� try try 1� 6ry e� 5ry 1� 1� ery cry 6� 5ry hry 5ry a� �ry �ry �ry �.� tiry <br /> ,pe e�¢1 ne ,oe a�e`I' ewe^ Jael anti a�^ <br /> 2 o e �aC aCJ p�J lCa PG <br /> Sampling Dates <br />
