Timer settings for the OSCAR-XO2 are short and very frequent(3 minutes off and 30 seconds on). The supply line needs to drain between doses, so the"on time" may need to be increased to compensate for filling the supply line prior to each dose.

The intent is not to have too much additional cover over the final C-33 sand layer. Placing they cover will inhibit plant root growth. Because the C-33 sand is sub-surface irrigated,grass and ground cover will grow rapidly,forming a firm protective cover over the OSCAR.At the end of the first growing season the C-33 sand layer will be as firm as native soil to walk on. Cover Options include: • Landscaping jute mat with grass seed or ground cover plantings • Thin layer of mineral soil low in organic content(<30%organics) • Thin layer of crushed or washed rock for wind erosion protection • Thin layer of bark or wood chips Do Not Cover C-33 Sand drainfield with: • Organic mix(manufactured top soil from compost) • Filter fabric OSCAR authorized dealer supply kit contact Info: • H.D.

Wastewater is collected In the septic chamber where gross solids are separated.The waste stream is aerated in the aeration chambers.Aerated effluent passes though the clarifier then into the pump chamber.The expected waste strength will be 30 mg/I CBODS and 5 mg/I TSS. Effluent is dosed through a 120 mesh disc filter to OSCAR coils,installed in ASTM C-33 sand. Effluent discharged from the coils is treated by the sand prior to infiltrating Into the receiving soil. Final discharge is expected to reach 2 mg/I CBOD, 1 mg/I TSS,and 36 FC/100 ml of effluent, meeting Treatment Level A.The X02 tanks can only be used with OSCAR coils. EH APPROVED Rhonda Thompson 07/29/2024 Design: The single family residence packages are designated as: Ond have t OSXOz•300, OSX02-360, OSX02.450, OSX02-480, and OSX02.600 and have the corresponding design flows of 240, 300, 360, 450, 480, and 600 gallons per day. The OSX02.240, 300, 360, 450, and 480, are standard packages. Design flows greater than 480 gallons per day are considered custom and wilt 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. An 6SCAR-X02 is two technologies combined together as one. 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, 750, 1125, 2250, 3,000, to 3,500 gallons per day (see Table 1- ). The ending OSCAR is designed in increments of 62.5 or 125 gallons per coil per day, p on coil model (see Tables 2 and 3). Consequently, a design for a 7 bedroom system (840 gpd) would incorporate a 1125 gallon per day X02 plus 14 OS-50 OSCAR coils (875 gpd). X02: Treatment Tank: The partition wall between the first and second compartment of the treatment tank must have a 4 inch by-pass hole or the bottom of the tee baffle located between 40% to 60% of the liquid depth. Discharge Tank: The patrician between the first and second compartment of the discharge tank must have a 4 inch by-pass hole located at least 18 inches above the floor of the tank and no more than 27 inches between the bottom of the by-pass hole and floor of the tank. Recommended hight is 18 inches, if possible.
