OSCAR XO2

The XO2 system is a complete onsite sewage treatment and disposal system. The XO2 comprises a septic tank, oxidation tank, clarifier, and an OSCAR for final treatment and dispersal. Testing completed by the National Sanitation Foundation (NSF) show the highest monthly average treatment level of 2 mg/l CBOD, 2 mg/l TSS, and 36 FC/ 100 ml.

OSCAR-XO2 only needs 12 inches of soil and has the smallest foot print available for Washington State. The coils used with the OSCAR-XO2 have the same physical format as any of the the OSCAR products, but there is a difference. The OSCAR OS-50 and OS-100 coils used in conjunction with the XO2 system have greater design flows: 62.5 gallons per day for the OS-50 coils and 125 gallons per day with the OS-100 coils.

The standard single family residence package is approved for up to 500 gallos per day. There are five design flow arrangements: 750, 1125, 2250, 3,000, and 3500 gallons per day for the XO2 unit. The OSCAR coils can be arranged for flow rates from 240 up to 3500 gallons per day.

XO2-IN-A-BOX

The XO2-in-a-BOX (XO2-B) is a slightly different application of the OSCAR-XO2 technology. The XO2-B is an OSCAR formatted like an intermittent sand filter. The OSCAR is built inside a 30 ml PVC liner that is supported by a wooden box. All the wastewater is treated by the XO2-B and collected in the underdrain. The underdrain directs the flow of treated wastewater to a pump basin or pump tank where it is dosed to a dispersal field: sub-surface drip or a low pressure distribution (LPD) system. 

The treatment capability of the XO2-B is treatment level A: 10/10 CBOD5/TSS and <200 FC/100 ml, MPN. This treatment level is achieved without a UV light. The XO2-B is comprised of an XO2 kit, OS-50 or OS-100 coils, and a 2 inch slotted underdrain. Additional items needed for the installation are tanks, a PVC , liner, and sand.

LOWeFLOW to XO2 retrofit

Existing OSCAR-LOWeFLOW systems can be converted to an OSCAR-XO2 system. This conversion will allow property owners to elect to eliminate the above ground LOWeFLOW unit and replace it with an aerator and diffusers. By doing so the system could be converted to a treatment level “A” designation. The local health jurisdiction may require a permit for the conversion.

OSCAR II

The OSCAR-II system is a dispersal technology for use as a stand alone technology or as dispersal technology with another treatment device. The three components to the system are: a septic tank or treatment unit, the pump chamber, and an OSCAR -II dispersal field. There are two options for the treatment vessel: a 1500 gallon septic tank (up to 500 gpd design flow) OR a treatment unit that must be listed on Washington State Department of Health’s List of Wastewater Treatment technologies.

The OSCAR-II with a 1500 gallon septic tank is approved as a treatment level D (TLD) system and will need 24 inches of soil. When the treatment unit is listed at a higher treatment level, say treatment level B (TLB), the OSCAR-II can be installed with soil depths between 12 and 18 inches.

OSCAR III

The OSCAR-III is an onsite sewage treatment and dispersal component for use with residential wastewater. Wastewater first passes through a septic tank and then into a dosing tank where it is dosed to OSCAR-III coils. Effluent is micro dosed into a layer of ASTM C-33 sand where physical, biological, and chemical treatment processes remove organic compounds and pathogens from the waste stream. Treated liquid then migrates downward to the receiving soil where final discharge of treated wastewater enters the soil environment.

The OSCAR-III is comprised of a 12 inch layer of C-33 sand media and a series of custom manufactured Netafim Bioline drip tubing coils. The sand media is placed on a prepared soil surface creating a level surface for the coils. OSCAR-III coils are then placed on the sand media and then covered with another 6 inches of sand media. No other cover material is needed.

Minimum size tanks for design flow upto 500 gpd is a 1,500 gallon septic tank and a 1,000 gallon pump chamber. Coil arrangements and minimum sand depth for the OSCAR-III system are different than the criteria for OSCAR-II. Please refer to the OSCAR-III manuals and drawing files listed below in this section.

System Description

The OSCAR-III is comprised of a 12” layer of C-33 sand media and a series of custom-manufactured Netafim Bioline drip tubing coils. The sand media is placed on a prepared soil surface, creating a level surface for the coils. OSCAR-III coils are then placed on the sand and covered with another 6” of sand media. No other cover material is needed.
Minimum tank sizes for design flow up to 500 gpd is 1,500 gallon septic tank and 1,000 gallon pump chamber. Coil arrangement and minimum sand depth for the OSCAR-III system are different than that for OSCAR-II.

OSCAR-in-a-BOX

The OSCAR-in-a-BOX (OSB) is a slightly different application of the OSCAR technology. The OSB is an OSCAR formatted like an intermittent sand filter. The OSCAR is built inside a 30 ml PVC liner that is supported by a wooden box. All the wastewater is treated by the OSB and collected in the underdrain. The underdrain directs the flow of treated wastewater to a pump basin or pump tank where it is dosed to a dispersal field: sub-surface drip or a low pressure distribution (LPD) system.

The treatment capability of the OSB is treatment level B: 15/15 CBOD5/TSS and <1,000 FC/100 ml, MPN. This treatment level is achieved without a blower or a UV light. The OSB is comprised of an OS-II kit, OS-100 coils, and a 2 inch slotted underdrain. Additional items needed for the installation are tanks, a PVC ,iner, and sand.
