Design CriteriA 40, rencor <br /> Hydraulic Loading <br /> Design average HLRA is 25 gpd/ft2(from page 15). Determine the textile area required based on Average Day Hydraulic Load,AHLRA using <br /> Equation 1.2: <br /> (3350 gal/d) <br /> f 2 <br /> AxcaA — 25.ga1/ft2d — 134 t <br /> The area associated with organic loading rate is the most restrictive and therefore the AdvanTex area should be a minimum of 210 ft2. <br /> Treatment Unit Options <br /> Option 1:Using AX-Max units —210 ft2 area <br /> AX-MAX225-35(Max unit includes recirc-blend tankage and discharge tankage) <br /> Option 2:Using AX pod units —210 ft2 area <br /> (3)AX100, 5025-gallon recirc tank, 1500-gallon discharge tank. (Recirculation-blend tank sized at minimum of 75%of QM,equates to 5,025 <br /> gallon minimum, per page 17 of Design Criteria; discharge tank size based on local regulation, but typically sized at minimum of 20%of QM, <br /> equates to 1340 gallon minimum) <br /> Other Design Notes <br /> • RV dump waste should be limited to no more than 20%of the design flow(average or maximum day)and metered into the system using <br /> small doses, preferably with a timed dose system. <br /> • Ensure access to the treatment site for maintenance activities. <br /> • Ensure availability of water at the treatment site for maintenance activities. <br /> Orenco Systems°•800-348-9843•+1 541-459-4449•www.orenco.com NDA-ATX-1 <br /> Rev.8,©10/20 <br /> Page 33 of 38 <br />
