OSCAR-LOWeFLOW System

View or download manuals here.

The OSCAR-LOWeFLOW™ (OS-LF) is a treatment and dispersal system that requires only 12” of soil to restrictive layer, has the smallest footprint of any technology available, and there is NO UV light! The OSCAR (Onsite Sand Coil Area Recharge) is an onsite sewage disposal and disinfection component when used with the LOWeFLOW™ treatment system. The OSCAR is comprised of a 6” layer of C-33 sand media and a series of pre-assembled Netafim Bioline™ drip tubing coils. The sand media is placed on a prepared soil surface. OSCAR coils are then placed on the sand media and then are covered with another 6” of sand media. The sand/soil interface is the discharge point of the treated wastewater. Vertical separation is measured from the original soil surface to the restrictive layer.

A 500 gpd LOWeFLOW filter. The LOWeFLOW™ system is a recirculating gravel filter with a loading rate of 25 g/ft2/d.

System Description

The OSCAR-LOWeFLOW™ treatment system is comprised of a recirculation filter, a septic tank, recirculation/mixing tank, headworks, discharge/clarifier tank, and the OSCAR unit.
Wastewater is collected in a standard septic tank where gross solids are settled out and primary treatment occurs. Septic tank effluent flows from the septic tank into the recirculation tank. Liquid in the recirculation tank is mixed with treated filtrate from the gravel filter. The mixed liquid is dosed to a drip tubing network called a Coil in the top of the LOWeFLOW ™ filter.

Treated filtrate from the LOWeFLOW™ filter flows by gravity back to the recirculation tank through the splitter valve. The position of the splitter valve determines the flow path of the filtrate. When the liquid level in the recirculation tank is high enough to seat the splitter valve, all of the filtrate passes into the clarifier/discharge tank, otherwise, all of the returning filtrate returns to the recirculation tank. Liquid accumulates in the clarifier/discharge tank. Liquid from the clarifier/discharge tank is timed dosed to the OSCAR coils where final treatment and dispersal occurs.

Design flows of the OSCAR-LOWeFLOW™ system range from 240 gpd to 100,000 gpd.

Treatment Level Expectations

The OSCAR-LOWeFLOW™ system was tested under National Sanitation Foundation’s standard 40 protocol and the Washington State Department of Health’s fecal coliform testing requirements. Average treatment level results for the six month test were:
• 5 mg/l CBOD₅
• 9 mg/l TSS
• 27 fecal coliform colonies/100 ml, MPN
• Turbidity ranged from 1-2 NTU
