Combined Treatment System

The Puraflo Peat Fiber Biofilter from Anua can be designed and installed as a combined treatment and effluent dispersal system. Treated effluent exits the modules via weep holes around the perimeter at the module base and flows into the dispersal system situated directly beneath. Available options include an in-ground or mounded pad. It features a small footprint and the ability to overcome site limitations such as seasonal high water tables, shallow soils or restrictive layers. Assistance is provided to designers and regulators on sizing and configuring the pad dispersal system. 336/547-9338; www.anua-us.com.

  Spider Valve

Clarus Environmental’s Spider Valve manifold assembly allows the appropriate distribution of effluent when regulations require pressurized splitting or when small lots require lateral lines of unequal length. When combined with a pump, orifice diameters within the manifold may be modified to ensure no lateral receives more than its share of flow. The incoming line should maintain at least 3 feet of distal pressure to ensure equal effluent splitting. The assembly must be installed at the high point of the system, permitting the effluent to drain from the valve to the trenches. It is available in models that serve up to 10 laterals. The assembly should be installed level inside a 24- or 30-inch access riser with lid. 800/928-7867; www.clarusenvironmental.com.

  Geotextile Sand Filter

The GSF Geotextile Sand Filter from Eljen Corporation provides advanced treatment and dispersal in the same footprint. The internal design provides sufficient void space to allow for aerobic conditions, while the Bio-Matt fabric promotes biological growth on its multiple surfaces. The fabric enhances system performance and keeps the biological growth away from the native soil, preserving the soil’s long-term acceptance rate. The unit’s lightweight and easy-to-handle modules allow for quick and convenient delivery and installation. 800/444-1359; www.eljen.com.

  Low-Profile Chambers

Quick4 Plus low-profile chambers from Infiltrator are optimal for shallow installations, providing maximum strength through center structural columns. At only 8 inches tall, they can be installed with as little as 6 inches of cover. They feature the Contour Swivel Connection, which allows 10-degree turns, right or left. They come in easy-to-handle 4-foot lengths, and provide even distribution of effluent to the soil. They don’t require heavy equipment for installation, and can be configured in a variety of inletting options and heights. 800/221-4436; www.infiltratorsystems.com.

  Ornamental Septic Vent

The Pagoda Vent from Pagoda Vent Company is an ornamental, but functional, septic vent that is easy to install, cost-effective, and blends into the landscape. It is offered in heights from 1 to 14 feet. The vent slides onto the vent stub, fitting with a seal on the stub pipe concealed inside the vent. Optional odor control filter cartridges are packed with septic odor-eating media. 888/864-1468; www.pagodavent.com.

  Distribution Boxes

Distribution boxes from Polylok/Zabel Environmental are available in 12- and 20-inch sizes, and accept 2-, 3-, 4- and 6-inch pipe. The 12-inch boxes come with stabilizing feet to anchor and prevent them from floating. They will accept risers to bring them to grade where necessary for convenient inspections. 877/765-9565; www.polylok.com.

  Carbon Filter

The Super Wolverine mid-size carbon filter from Simple Solutions holds between 8 and 10 pounds of activated carbon and is available with inlet sizes between 3 and 6 inches. It has a pressure drop of only 0.2 inches W.C. at 10 cfm, making it ideal for larger aerobic systems found at restaurants or on small commercial buildings. It also has an optional saturation indicator for monitoring the life of the carbon bed, and uses a 2-inch drain plug for easy media replacement. It is also available with a solar-powered fan for active ventilation. Common applications include grease trap vents, commercial building plumbing vents, holding tank vents, septic tank vents and gravity mainline sewer vents. 866/667-8465; www.industrialodorcontrol.com.

  Pipe Stand

The STF-BTPS “bow tie” pipe stand from Sim/Tech Filter is designed for use in chamber systems where distribution piping is suspended above the soil. The stand is independent of the chamber, allowing the pipe to be installed prior to chamber installation and also before the squirt test is performed. It installs by a squeeze-and-release action that makes installation quick and easy. It can be installed on the pipe before placing in the trench, and is easily adjusted to any desired spacing. It stores flat for economical shipping and easy storage, and is available to fit 1-, 1 1/4-, 1 1/2- and 3-inch pipe. 888/999-3290; www.simtechfilter.com.

  Roof Vent Filter

The Sweet Air Filter from Tuf-Tite is designed to eliminate offensive odors from roof vents. It is a self-cleaning D-Vent filter using activated carbon to remove odors. It uses heat from the sun to automatically clean and refresh itself. The filter comes with a removable cap for easy carbon replacement, and fits standard 2-, 3- and 4-inch pipe, with custom sizes available. 800/382-7009; www.tuf-tite.com.
