Products
SAGPack™
The SAGPack system is designed to condition, compress, and remove moisture and siloxanes from biogas. It includes patented technology for stratifying the media and calibration of the siloxane removal capabilities of the system based on the different species identified during gas testing. System size is based on gas velocity, temperature, pressure, and SIL-2 gas analysis. Treated gas operating conditions are 20-40 percent RH at a maximum of 80° F.

AGPack™
The AGPack is a conditioning system that removes macro particles like sticks, stones and dust from a biogas source by compressing and drying the waste stream. Ideal for dairy manufacturing, food processing and select digester streams, the AGPack is also used to support SAGPack, AFT’s industry-leading contaminant removal system.

CO2 Strip
CO2Strip is the first step in creating pipeline-grade methane out of a waste stream. The system conditions a waste stream for multiple contaminants at once; namely carbon dioxide, sulfur and siloxanes by chilling and flashing the gas with recovered water.

WaterStrip LP™
WaterStripLP is a counterflow water stripping product that removes sulfur from inlet gas by utilizing secondary plant water. Through this process, 50-70 percent of the sulfur is removed from the digester gas. Effluent is directly discharged or recycled. It can also be used in agricultural areas where sulfur may be beneficial.

SulfrPack CIS™
SulfrPack CIS is anaerobic or aerobic, iron sponge-based treatment system that eliminates that sulfur from biogas streams at ranges of 0-2,500 ppm. This proven technology remains adept while working with sewage gases, low-pressure systems and high-pressure natural gas. An extended use occurs when a one percent maximum of air is added the system. At this point, it will assume aerobic function and improve its efficiency by 25-50 percent. The additional oxygen used up in the reaction does not carry forward in the system and in-situ regeneration is possible if you combine aerobic and anaerobic operations.

SulfrPack ST™
SulfrPack ST is a biogas treatment system that removes sulfur from waste streams at a range of 0-2,000 ppm. SulfrPack ST is also equipped with a highly-effective odor control system that neutralizes sulfur and light mercaptan-type odors from any air or gas stream. This high-capacity product’s reliability in partially to fully humid air makes it unique to other sulfur removal systems.

SulfrStrip™
SulfrStrip is an economical proven sulfur removal technology that uses a chelated iron chemical scrubbing system to remove hydrogen sulfide (H2S) and recover it as elemental sulfur. SulfrStrip is ideal for gas flows with high sulfur and low scfm. In sensitive system applications, SulfrPack can remove any remaining sulfur.

BioStrip™
BioStrip is a completely biological technology for reducing sulfur. In biogas with concentrations of sulfur below 15,000 ppm, BioStrip provides the lowest operating expenses per pound of sulfur removed of all AFT solutions. In addition, the elemental sulfur byproduct can be resold to further reduce expenses.

AirWedge™
AirWedge is designed to safely move media between a facility’s SAG™ and HOX™ systems and its shipping containers. The process of media replacement is simplified by enabling workers standing on the ground to easily load media into the top of the treatment vessels. Once the media enters the system, an air educator operated by a small blower transfers the media from a small hopper to the top of the vessel. The AirWedge is available in several different configurations, all of which are further customizable to meet particular project needs.
