Wastewater is collected in the septic chamber where gross solids are separated. The waste stream is then aerated in the aeration chamber Aerated effluent passes through the clarifier then into the pump chamber. The expected waste strength from the X02 will be 30 mg/I CBODS and 5 mg/I TSS. Effluent is 's through a 120 mesh disc filter to OSCAR coils, installed in ASTM C-33 sand. Effluent char from the coils is treated by the sand prior to infiltrating into the receiving soil. 10 r,7t9ri) t level in the final discharge is expected to reach 2 mg/I CBOD, 1 mg/I TSS, a v f.� eeting Treatment Level A. The X02 can `V only be used with the OSCAR. '' s m 1 s 9 51 1 s� or EN w t[ EN esi 1 EXPIRES nsno, /N�11 Design: Single family residence packages are designated as: OSXO2-240, OSX02-300, O5X02-360, OSXO2-450, OSXO2-480, and OSX02-600 and have the corresponding design flows of 240, 300, 360, 450, 480, and 600 gallons per day. The OSX02-240 - 480 are standard packages. Design flows greater than 480 gallons per day are considered custom and will require design assistance from Lowridge Onsite Technologies, inc. For the standard single family residence OSCAR-X02 package parts list see the appendix. The X02 can only be used with OSCAR coils. All tanks must be approved by Washington Department of Health as wastewater vessels. The system can be designed in increments of flow up to 3500 gallons per day. The OSCAR has different sizing criteria than the X02. The X02 is designed in increments ranging from 500 to 3,500 gallons per day (for reference, see Table 1-2). The OSCAR is designed in increments of 62.5 or 125 gallons per coil per day, depending on coil model (see Tables 2 and 3). Consequently, a design for a 7 bedroom system (840 gpd) could incorporate two 1750 gallon, two compartment tanks plus an addition aerator (OXz+1 kit) with 14 0S-50 OSCAR coils (875 gpd). X02: The tanks for the XO2 can be arranged in different formats. One option is to use two double compartment tanks of the same size, either made of polyethylene or concrete, with the following criteria: Treatment Tank: The partition wall between the first and second compartment of the treatment tank must have either a 4 inch by-pass hole or the Men bottom of a tee baffle must extend down between 40% to 60% of the liquid depth of the tank. 1 Discharge Tank: The partition between the first and second compartment of the discharge tank must have a 4t inch by-pass hole located at least 18 inches above the floor of the tank or no more than 27 inches between the bottom of the by-pass hole and floor of the tank. Recommended hight of by-pass hole is 18 inches. To determine the tank size for design flows greater than 500 gpd, the tanks can be up size proportionally. Example: - - • Tanks for a 500 gpd design = 1,000 gallons A 7-bedroom design (120 gpd x 7) is 840 gpd. 840 gpd/500 gpd = 1.68 or 68% increase P n im nk size for 840 gpd = 1,000 gal. x 1.68 = 1,680 gallons AN A a 1750 gallon, two compartment tank can be used. - \ \V m F-y IDE 18 CINDY E. IT LI D IG pik\ 2,4n nI • ,ceHlSa, v L� For tanks with water tight, structurally sound partitions: for both the treatment tank and discharge tank a double compartment tank with tee baffles can be used (no flow through ports). Flip the discharge tank around so the smaller compartment is first as shown (see Illustration 2). The clarifier chamber is to remain full. .-ALL l_ r u - r i- - F s 1 • g 3 �.v+,�4:ka. - --s..^r. ,� , .. ho-. TA. ., ? Illustration 2 As the daily design flow rates increase, larger tanks will be needed. It may become necessary to have individual tanks for each chamber or a combination of tanks to meet the volume requirements. For example: 3.000 god design flow (refer to Table 1-2). Septic chamber = 4000 gal. needed, use a 3000 gal. tank + 1000 gal. tank. Aeration Chamber = 2-1000 gal. tanks. Clarifier chamber = 2- 1000 gal. tanks. Pump chamber = 3000 gal. tank + 1000 gal. tank. " ' i 3 In this example, the septic chambers could be connected using standard tee . baffles making a two compartment chamber. The aerator chamber could be arranged the same as the septic chambers. Half of the diffusors would be placed in each 1,000 aeration chamber. The clarifier chambers could either use tee baffles or be connected together below the liqui level.

Deviation from this design without prior approval from the designer and Mason County Health Department will make this design null and void. • 22. This design was sized per Washington Administrative CodeWAC246-272A-0230. The operating capacity is based on 45 gallons per day per capita with two persons per bedroom. The minimum design flow per bedroom per day is the operating capacity of ninety gallons multiplied by 1.33. This results in a mi urn design flow of one hundred twenty gallons per day. This creates a surge factor o but anticipated flow is ninety gallons per bedroom per day. Pe pA M1e ems„ IA 5 Sic 1)or IND w it 1\ LIG ODE GNER� ExPIgLS , 10 System Owner Responsibilities: 1.
