Eliminite Total Anoxic Nitrification Combination (TANC) 3000-7000


Eliminite’s TANC™ streamlines the advanced treatment process by combining a fully sized septic tank, recirculation tank, dose tank and advanced treatment filter within a single compartmentalized, fully assembled unit. The TANC™ achieves aerobic nitrification and anaerobic denitrification, solids settling and significant BOD reduction within one compact treatment tank. Superior system scalability, simplified installation and maintenance, and reliable treatment performance distinguish the TANC™ from its competitors. Eliminite's TANC™ series represents a more compact and efficient alternative to common multi-tank configurations, allowing designers to specify a single, standard residential TANC™ system for homes with up to 13 bedrooms (may vary by state). 


The TANC™ is delivered to each site pre-assembed and pre-plumbed for the contractor's convenience. The unit can be installed in minutes with basic excavation equipment, thereby minimizing site disruption and reducing installation expenses. The only visible component of the TANC™ system are its two 24" access ports, which are unobtrusively located at ground level. Moreover, maintenance requirements for the TANC™ system are minimal because every treatment component is centralized within a 6ft x 16ft space.


The Eliminite pump, drainfield pump, MetaRocks® media bed and patented Lung® air entrainment device are all factory-installed within the TANC™ and are readily accessible to the maintenance provider through strategically placed access ports. Upon request, Eliminite, Inc. can also pre-wire the TANC™ system to its control panel in the factory so that the licensed electrician in the field can simply connect the main power source to the control panel. The septic tank component of the TANC™ can be pumped every 3-5 years (or as dictated by local regulations) in the same manner as a stand-alone septic tank.


Where system designers must accommodate tight setback requirements and/or steep slopes, Eliminite's TANC™ is the ideal advanced treatment option. Sloping sites can be problematic for multi-tank systems because even a slight shift in the slope can disrupt or shear connections between tanks, precipitating costly repairs and further site disruption.


Standard TANC™ systems are available in 3,000-7,000 gallon models, as well as semi-custom and custom models for larger flows and for clustered, community and commercial applications. A community TANC™ system is an affordable and efficient advanced treatment option for almost any decentralized land development project.

Eliminite C-Series Offers Affordability and Benefits Local Businesses


The Eliminite C-Series was developed in response to the growing demand for a more affordable advanced treatment option in the rural west. Eliminite Inc. has teamed up with qualified precast concrete manufacturers who provide state-approved concrete septic tanks that serve as sturdy containment housing for the Eliminite system. The Eliminite's proprietary components have been adapted to accommodate the dimensions of each precaster's standard line of concrete septic tanks. Eliminite kits are custom-built and shipped from our manufacturing facility in Three Forks, MT to each tank manufacturer's yard, where trained staff members install the kit into a standard concrete tank. Several lightweight kits may be efficiently packaged and shipped in a single load, thereby reducing freight charges and carbon emissions.


While most manufacturers only offer a "package plant" system in a limited size range, the Eliminite C-Series is available in a variety of sizes and configurations, from 1,500 gallon models to 3,500 gallon models and beyond. Larger-scale community and commercial Eliminite C-Series systems may be installed in custom-built precast concrete vessels that are assembled in sections, at the job site. In certain regions, overall system cost can be cut by up to 50% simply by using concrete containment vessels in place of fiberglass tanks.


Eliminite Community and Commercial Systems are Customized for Every Site

Eliminite's advanced treatment technology is inherently scalable, so options for clustered, community and commercial systems are virtually limitless. Every clustered, community and commercial Eliminite system is customized and adapted to each site's unique topography and to each developer's unique vision for his or her project, so no two systems look alike. Eliminite's design team "listens to the land" and considers developer's preferences in the system selection process.
Eliminite's TANC™ technology has been popular among developers due to its relatively compact footprint and reduced installation costs. Treatment capacity is easily increased by upsizing Eliminite components and tanks. This simply means using larger diameter piping, greater media volume, bigger tanks and more powerful pumps. This simple design spares significant square footage when compared with typical multi-pod clustered, community and commercial systems, allowing property owners to preserve more open space or to take advantage of more development opportunity.


Another important (though often neglected) factor in selecting an advanced wastewater treatment system for larger flows is aesthetics. No one wants to see multiple rows of risers and manhole covers or access lids scattered across the landscape. Moreover, each additional lid/access point represents an increased probability that wastewater odor will escape from the system and become a nuisance. Sub-grade Eliminite systems--regardless of which configuration is settled upon--are designed with just a few strategically placed access points, which are flush with the ground and are virtually invisible from a short distance away.



Innovative Community/Commercial Designs Merge Centralized and Decentralized Technologies to Optimize Treatment for Larger FlowsAnother pragmatic design option is Eliminite's centralized above-ground design. Concealing any treatment system below ground requires additional excavation work and extensive landscaping efforts, which may add more expense than the treatment system itself. Eliminite resolves this issue through a compact, inconspicuous, above-ground centralized treatment system design that offers several major advantages over sub-grade systems.


The above-ground Eliminite system is housed within a small building that is designed to meld with the surrounding landscape and the architectural trends of the development it serves. For instance, a stucco building with terra cotta shingles might be most appropriate for a desert development in the southwest, whereas a timber frame or log building might be better suited to a ski resort development in the Rockies.


Believe it or not, these tastefully designed buildings are small, affordable, and simple to build, and they actually lend aesthetic appeal to the development. Moreover, these buildings come equipped with electricity and plumbing, and they are temperature controlled. The Eliminite's primary and secondary clarifiers, packed bed bioreactors,pumps, piping and controls are all strategically located within this single, one-room building.

Operating and maintaining an above-ground Eliminite system that is housed in a temperature-controlled, fully plumbed and wired building is almost effortless. O&M providers can simply walk into the building and look at every single component without digging through snow or laboring to unscrew access lids in the blazing heat. The electrical and mechanical components of the system are protected from the elements and will operate more smoothly and efficiently as a result, and the overall life of the system will be longer. Additionally, because the Eliminite relies upon natural biological processes to purify the incoming wastewater, the warm building will increase treatment performance dramatically, particularly in cold mountain climates. Microorganisms become sluggish and struggle to survive in cold temperatures, which is why treatment performance on biological treatment systems typically improves during the summer months and tapers off during the winter months. The building provides a hospitable, 60-70 degree environment year-round, which promotes the increased biological activity that produces reliable, consistent advanced treatment results. In some areas, the system's treatment capacity can be increased simply due to the temperature-controlled environment. Warmer wastewater increased biological activity are a perfect recipe for enhanced system performance.
