Orenco Systems Inc. March 2002 AdvanTex AX 10 Test Report ANSI STANDARD 40 PROTOCOL According to ANSI Standard 40 protocol, testing and evaluation of a plant should fulfill the following items. Plant Start-Up Plant installation should occur under the supervision of the manufacturer. Once the plant has been installed the manufacturer, should inspect the plant to ensure that it has been installed and is running to their satisfaction. At this point the manufacturer will sign an Installation Sign-off Form. Following the installation, the system will undergo a hydrostatic test. For this test, the system will be filled with water to its high water alarm level and allowed to sit for at least 24 hours. During this time there should be no more than a 0.5% change in the initial water level. At this point the plant is ready for startup. The plant should then be drained down to 66% its normal operating volume and filled with 33% sewage sludge at which time the plant is started up. The plant will have a three week period to reach steady state. The manufacturer may choose any time during this period to begin ANSI Standard 40 testing. Plant Loading According to ANSI Standard 40 protocol the system should be tested for 26 consecutive weeks. During this time the system should be tested for 16 weeks using its daily rated hydraulic loading, 7.5 weeks of stress test loading and another 2.5 weeks using its daily rated hydraulic loading. The plant should be dosed with raw municipal wastewater, on a daily basis, 7 days a week, at its rated daily hydraulic capacity. Daily dosage will occur from 6:00 to 9:00 am, 11:00 am to 2:00 pm. and 5:00 pm to 8:00 pm. These periods have been chosen to mimic times when the hydraulic loading to the system is expected to be at its highest. The system will be dosed 35%, 25% and 40% of its total daily load during these three periods. Stress Testing The Stress Testing should begin 17 weeks into the program. These tests are used to mimic four non-ideal conditions, that the treatment system would be subjected to, during regular operation. These tests are a Wash Day Stress, a Working-Parent Stress, a Power/Equipment Failure Stress and a Vacation Stress. Wash Day Stress This test evaluates the systems ability to perform when detergents and fabric softners are added, as part of a regular wash cycle. During this stress, the plant should be dosed with Nova Tec Consultants Inc. Page 36 of 38
