Commercial Septic Systems

Conventional commercial septic systems use leach fields and the surrounding soil to treat wastewater and other effluent. Although this strategy does produce partially treated water, it also sends waste into the ground and underlying aquifer. And over time, this buildup can lead to:

  • Irreversible groundwater contamination and soil erosion.
  • Lost business productivity and costly repairs.

Passive Septic Systems

Eljen Geotextile Sand Filter (GSF)

Geotextile fabric and plastic core materials function together to provide vertical surface area for biomat management and oxygen transfer in each GSF Module.  In the GSF System, treated effluent is applied to the receiving soil, which increases soil acceptance.  Additional filtration and dispersal is provided by the Specified Sand layer under and around the GSF units.  This sand layer remains in an unsaturated state allowing for the free flow of effluent and beneficial bacteria. 

Eljen Geotextile Sand Filter Key Features:

  • Integrated treatment and dispersal
  • Site installation flexibility
  • Reduced impact on the site
  • Easy to handle, lightweight

How the GSF System Works

In lieu of onsite septic leach field systems, Eljen offers its GSF (Geotextile Sand Filter).  Testing performed by independent, third parties verifies the performance of the GSF under different conditions, but the system is composed of a primary treatment zone (containing the GSF Module) and a secondary treatment zone (Specified Sand layer). Over the GSF Module is a perforated pipe that distributes septic effluent into the corrugations created by the plastic core.

Primary Wastewater Treatment

  • The GSF Module is designed to manage the biomat and relieve the native soil of the burden of treatment and biomat development.
  • Aerobic bacteria can grow on the GSF Module’s geotextile fabric interface thanks to open-air channels within the module. This promotes oxygen absorption in the system.
  • The unique design of the GSF Module provides a large surface area for the biological treatment of contaminants and nutrients.
  • The top and side sections of the Eljen GSF Module are covered with anti-siltation geotextile fabric to prevent fines from migrating into the open channels.

Secondary Wastewater Treatment

  • As well as protecting the soil from compaction, Specified Sand acts as a filler, preventing cracks and crevices from appearing in the ground.  
  • The filtered effluent drips into the Specified Sand layer, with precise grain size allowing unsaturated flow into the surrounding native soil.
  • The native soil serves as the final filtration layer and recharges the groundwater.

Specified Sand Layer

All Eljen GSF Systems must be installed using ASTM C33 sand that passes no more than 10% through a #100 sieve and no more than 5% through a #200 sieve to ensure that the system functions properly. This specification is the key to successful secondary treatment before the wastewater reenters the native soil.

Presby Enviro-Septic

septic systems for commercial businesses

But with the Advanced Enviro-Septic® wastewater treatment septic system, it’s possible to avoid the above septic-related health and environmental issues. Unlike with traditional commercial septic system water treatment solutions, the Advanced
Enviro-Septic® system uses a living, breathing bacterial ecosystem to remove up to 99% of contaminants before sending treated water into the surrounding soil.

This passive filtration technology combines treatment and dispersal into one small footprint, thus minimizing the environmental impact of commercial-scale wastewater treatment.

However, the benefits of this patented treatment technology don’t stop there. Below are just some of the reasons why the Advanced Enviro-Septic system is increasingly the “system of choice” for business owners and commercial property developers across the country.

Benefit 1: The Advanced Enviro-Septic® System Is Affordable

Because of its streamlined design, Advanced Enviro-Septic products install very quickly, helping you avoid many of the excavation and labor costs associated with conventional septic system installations.

In addition, operating and maintaining Advanced Enviro-Septic® systems is significantly cheaper, given that there are no moving parts, additives, or chemicals involved. Passive filtration allows the Advanced Enviro-Septic pipe to continue operating at peak performance – devoid of wear and tear. This unmatched endurance removes the need to invest in costly replacements or upgrades.

Benefit 2: The Advanced Enviro-Septic® System Is Powerful

Although the Advanced Enviro-Septic® wastewater treatment system is smaller than traditional water treatment solutions, it matches the raw performance of much larger septic systems. Even with commercial-sized applications, the Advanced Enviro-Septic® system consistently removes up to 99% of all contaminants to produce highly treated water that is safe enough to send back into the surrounding soil.

Benefit 3: Advanced Enviro-Septic® Technology Is Versatile

Thanks to its compact design, Advanced Enviro-Septic® pipe can be installed practically anywhere, whether you’re working with:

  • Flat or sloping terrain.
  • Open or confined spaces.
  • Straight or curved contours.

This unrivaled flexibility makes the Advanced Enviro-Septic® product the ideal solution for a broad range of residential and commercial applications. And because of its modular design, you can easily add as little or as much capacity as you need.

Benefit 4: Advanced Enviro-Septic® Systems Are Green

There are a number of commercial septic systems that approach the treatment standards of the Advanced Enviro-Septic® system. But most of these alternatives rely on leach fields to treat effluent. And over time, this often results in soil degradation and aquifer contamination.

By contrast, the Advanced Enviro-Septic® system technology safely removes up to 99% of all contaminants before sending highly treated water back into the ground. This helps to protect nearby waterways and other endangered resources. In fact, the Advanced Enviro-Septic® wastewater treatment system currently exceeds the on-site septic system secondary treatment guidelines established by the Environmental Protection Agency (EPA).

Is the Advanced Enviro-Septic® System Right for Your Commercial Septic System Needs?

If you’re looking for a commercial septic system that is greener, cheaper, and more powerful than most commercially available alternatives, the Advanced Enviro-Septic® system pipe may be the perfect wastewater treatment solution for you.

Mechanical Treatment Systems


ECOPOD-N Advanced Wastewater Treatment Unit

Delta ECOPOD-N Advanced Wastewater Treatment Units are an innovative approach to onsite wastewater disposal where nitrogen reduction is required. The ECOPOD-N technology has been tested under NSF/ANSI 40 and 245 with an average nitrogen reduction of greater than 50% and met and exceeded Class 1 requirements with an average effluent quality of 9 mg/L BOD5 and 8 mg/L TSS.

Delta ECOPOD-N Advanced Wastewater Treatment Unit Features:

• Oxygen is pumped into the system allowing the bacteria thrive and grow in much greater numbers than would occur naturally. This “overpopulation” of bacteria speeds the process of • breaking down the sewage, making it safe for release into the environment.

• ECOPOD-N units significantly reduce BOD, TSS, fecal coliforms, and nutrients in the wastewater.

• Nitrification and denitrification occur in a single tank.

• Features a fixed-film process which is characteristically stable, reliable and sturdy. Fixed-film is a preferred treatment process for onsite wastewater treatment systems.

MicroSeptic EnviroServer

MicroSepTec has taken the EnviroServer ES Series and redesigned it for commercial strength (CS)applications. Sometimes, the simplest solution is the best and that’s the case with the EnviroServer. The CS Series was engineered to treat commercial high strength wastewater in a small, simple, and economical footprint while providing reliable treatment and superior effluent quality. Simple, because the entire treatment system is in one tank. Simple, because the only moving part is the compressor. Simple, because there is minimal intrusion to the landscape. Simple, because the process is accomplished with aeration and agitation, the same technology as sewer treatment plants. Simply simple!
