�.i <br /> EXECUTIVE SUMMARY <br /> Testing of the MicroSepTec EnviroServer 600 was conducted under the provisions of ANSIINSF Standard <br /> 40 for Residentiff Wast eater Treatment Systems (January 1999 revision). ANSI/NSF Standard 40 was <br /> developed�fray the NSF Joint Committee on Wastewater Technology. <br /> The performance evaluation was conducted at the Bazan Bay STP Wastewater Technology Test Facility <br /> located in North Saanich, British Columbia, using wastewater diverted from the Dean Park Estates municipal ' <br /> wastewater collection system. The STP Wastewater Technology Test Facility is a Standard 40 <br /> subcontractor for NSF. The evaluation consisted of five days,of dosing without sampling to allow for plant <br /> start-up, sixteen weeks of dosing at design flowl'seven weeks of-stress test and three of dosing at design <br /> flow. Sampling started in the late spring and continued through the Fall, covering a range of operating <br /> temperatures. <br /> Over the course of the evaluation,'the avereige luent CBOD.was 6 ing&, ranging between less than 2 and <br /> 62 mg/L, and the average effluent suspended solids was 8 mg/L, ranging between less than 2 mg/L and 45 <br /> mg/L. <br /> The EnviroServer 600 produced an effluent that successfully met the performance requirements established <br /> by ANSI/NSF Standard 40 for Class I effluent: <br /> The maximum 7-day arithmetic mean was 40 mg/L for CBODS and 30 mg/L for suspended <br /> solids, both at or below the allowed maximums of 40 and 45 mg/L respectively. The maximum <br /> 30-day arithmetic mean was 22 mg/L for CBOD3 and 16 mg/L for suspended solids, both below <br /> the allowed maximums of 25 and 30 mg/L respectively. <br /> The effluent pH during the entire evaluation ranged between, 6.2 and 7.9, within the required range of 6.0 <br /> to 9.0. The plant also met the requirements for noise levels (less than 60 dbA at a distance of 20 feet)and <br /> color, threshold odor, oily film and foam. <br /> r <br /> 99116=1510B0 This , may not be mprodtxed in:whole or in part Page 2 of 49 <br /> Final Report without the expressed wrt tan consent of MSF International.
