SoilAir™ GEOMATRIX
Description of Technology
Descriptions for proprietary technologies are from the Massachusetts DEP Approval Letters for the technology.
The SoilAir System is designed for enhancement of leach fields or soil absorption systems (SAS). The System blower introduces air directly into the SAS for optimum ventilation. This supplemental air displaces carbon dioxide, methane and hydrogen sulfide and increase oxygen levels within the SAS and surrounding soil. This subsequently increases the microbial population which in turn reduces the clogging of the biomat and organic accumulations at the soil interface; thereby improving SAS capacity.
SoilAir components include a blower and either a timer or a microprocessor based controller in a small enclosure. This enclosure is connected to a power supply and an air line to the existing piping running from the septic tank to the SAS. The System typically includes other components, installed to monitor septic system operation and to determine aeration frequency. A phone line is necessary for the remote telemetry option.
The smallest model RF-3952TB is designed for up to 5 bedrooms or 400 mg/L BOD sanitary wastewater and is operated on a 115 volts electrical supply. It is controlled by a 7 day programmable timer and an optional line voltage float switch. The timer can be set to control the operation of the system on a daily basis, allowing the system to be shutdown on certain days or times, or to run more or less on other days, depending of flows or other constraints. If blower static back pressure is greater than 2 inches of water column, and the system is configured for gravity flow, the timer must be programmed to shut down the blower to allow water to pass to the leach field. Alternatively, on a gravity system, an optional float switch can be installed in the outlet baffle or effluent filter to automatically dose a set volume of effluent to the SAS. A float can also be utilized in conjunction with a pump system to alternate the flow of air and water.
The System requires installation of a check valve in the existing system venting between the septic tank and the dwelling to prevent loss of the added System aeration.
