The effectiveness of SepticNET™ at removing Total Nitrogen, Biochemical Oxygen Demand (BOD), and Total Suspended Solids (TSS) for residential wastewater and its design flexibility provide numerous advantages of using SepticNET™ for wastewater treatment. Some advantages are:
320% Better Contaminant Removal: SepticNET™ is approved to remove total nitrogen to <7.5 mg/L; the major competitor is approved for 24 mg/L, thus SepticNET™ provides more than three times the treatment for a comparable cost.
No Nitrate Mixing Zone: Using SepticNET™ streamlines the permitting process by eliminating the need for a nitrate mixing zone analysis by MDEQ, which in-turn saves money for the owner.
Smaller Drainfields: SepticNET™'s highly efficient treatment results in smaller drainfields which significantly reduces costs for the project.
Longer Drainfield Life: Less loading to the drainfield extends its life and thus saves replacement costs for future operations of the treatment system. It is highly likely that the drainfield of a SepticNET™ system may never have to be replaced as a result of bio-mat build-up or biological plugging.
Low Operation & Maintenance Cost: The SepticNET™ system has few mechanical parts and was designed to run unattended for long periods of time. Also, no hazardous chemicals, such as methanol, are used in the SepticNET™ system and no complicated dosing/recycle systems are needed to achieve the superior treatment levels.
Easily Expandable: The SepticNET™ is a modular treatment system that is designed to effectively treat wastewater with highly variable flows and concentrations. Should additional treatment objectives be required in the future, components can easily be added to SepticNET™ without major system modifications.
Montana Invented, Tested, and Manufactured: SepticNET™ was developed and tested in Montana, using funding from Water & Environmental Technologies and a grant from the Montana Board of Research and Commercialization Technology. Testing and developing the system in Butte proves it can effectively operate in the adverse environmental conditions that exist throughout many areas of the state. Also, because SepticNET™ is manufactured in Montana, service and technical expertise for the system is readily available.
SepticNET™ Performance Data
Wastewater treatment is a complicated process involving numerous biological components and various environmental conditions. SepticNET™ modular design allows it to efficiently remove TN, BOD, and TSS; and allows the system to be easily upgraded to remove additional contaminants as needed. For example, a phosphorous module is already available for SepticNET™ and testing is being conducted on modules designed to remove pharmaceuticals and personal care products. The following items summarize SepticNET™ performance data obtained from systems located around Butte, Montana, which provides an accurate expectation of how SepticNET™ will perform at other Montana locations (other systems have been developed and tested at locations with much different conditions than those we encounter regularly in Montana).
