8 <br />4 <br />It should be recognized that some effluent samples will have contaminants of concern <br />above the discharge requirements. This occurs because the purification level is <br />systematically backed off until break through or a non-compliant discharge level is <br />achieved. This is done in order to determine the optimal treatment condition and its <br />corresponding rate. <br />9. Sampling plan <br />The following sampling plan provides the guidelines for successful ongoing operation of <br />the demonstration unit. It is the client’s responsibility to conduct the samples and analyze <br />the samples in a certified laboratory. <br />After successful commissioning of the demonstration plant, supervised by Fluence, an <br />approximate acclimation period of 1-3 weeks will take place. During that period the <br />biology will develop on the MABR towers and will begin Nitrifying. During the acclimation <br />period, 2 grab samples per week should be taken from the influent wastewater and the <br />effluent water (samples should be taken per the guidelines referenced in “Standard <br />Methods for the Examination of Water & Wastewater” - Lenore S. Clesceri, American <br />Public Health Association, latest edition) The following elements should be analyzed in a <br />certified laboratory: <br />A. Ammonia (NH +) <br />B. BOD5 <br />C. pH <br />D. Dissolved Oxygen (a mobile DO device should be used). <br />After the biology had acclimatized and the Demonstration system is producing effluent <br />that meet the Ammonia effluent requirement, the following samples should be taken as <br />part of the routine operation of the Demonstration system: <br />A. Ammonia (NH4+) – Influent and effluent grab sample, once per week. <br />B. BOD5 – Influent and effluent grab sample, once per week. <br />C. TSS – Influent and effluent grab sample, once per week (recommended). <br />D. Dissolved Oxygen (a mobile DO device should be used) – Grab sample should <br />be taken from the last MABR chamber, once per week. <br />E. Nitrate (NO3-) – Influent and Effluent grab sample, once per week <br />(recommended). <br />* In case one of the samples exceeded the estimated influent concentration/effluent <br />requirement concentration, an additional sample should be taken after consultation with <br />Fluence. <br /> <br />10. Valuation <br />The replacement value of the Demonstration Equipment is the value declared on the <br />Commercial Invoice, as submitted to US Customs. This is the value used for Insurance <br />purposes and is currently valued at $280,000 USD.
