Because the biological processes are the same, this is considered a non‐differentiator and highly dependent on operating conditions.aSpare parts cost lists provided by each bidder varied in level of detail; the assumption is made that this cost will be approximately the same for all three proposals and not a differentiator, therefore this is not included in the comparative present worth.bSpare parts cost provided by Ovivo given as a 20‐year total cost. Annual cost shown is the 20‐year total cost divided by 20.cCloacina provided equipment replacement cost, whereas H2O Innovation and Ovivo did not. Value shown here for completeness, but not included in comparative present worth.dH2O Innovation provided no calculation detail of annual projected power usage; Ovivo calculated power use for only when duty units are operating; Cloacina appears to have calculated power use assuming all duty and standby units are on for the same number of hours.eNaHOCl and Citric Acid are used for membrane cleaning; NaOH is used for pH control of treatment process; MicroC is a proprietary glycerin‐based carbohydrate used as a carbon source for biological processes.1 of 6 Port Hadlock Water Reclamation FacilityMBR Equipment Bid EvaluationAssumptions for Comparative Present Worth Calculation(P/F, i=3%,n=10)=F/(1/(1+i)^n) 0.7441(P/A,i=3%,m=20)=14.88i, discount rate3%discount rate in 2021 Facility Plann, membrane replacement year10m, present worth evaluation period20Power, $/KWH0.101unit cost in 2021 Facility PlanNaHOCl 12%, $/gal$0.89unit cost in 2021 Facility PlanCitric Acid 50%, $/gal$4.29unit cost in Ovivo proposal;
