At ARS, we are proud to be on the forefront of remediation technology and hold numerous patents and trademarks in the field.
ARS considers its intellectual property (IP) assets critical to its current and long term business success. The IP consists of 2 granted patents, 2 granted trademarks, 1 pending filed patent and 1 soon-to-be-filed trademark. Our corporate branding and recognition has been achieved through 25 years of implementing our own technologies, sub-licensing academia technology through exclusive and semi-exclusive licensing agreements, numerous awards and more than 58 published papers covering its projects and services. Identification of the company and its technology in more than one dozen government guidance documents report this claim.
In addition, our company’s field services know-how was gained through 25 years of applying innovative in situ treatment technologies and brand recognition through exclusive and semi-exclusive licensing agreements. ARS Technologies and its predecessor Accutech Remedial Systems (ARS) brands are synonymous with the environmental fracturing and advanced injection industry it pioneered and currently leads.

“Ferox™”, US Patent
US Patent #5,975,798
Developed by ARS, this in situ treatment process for contaminated soil and groundwater is based on a gas injection process technology and had been demonstrated to treat a wide range of hazardous compounds including halogenated hydrocarbons, heavy metals, PCBs and pesticides.
“Atomized Biological Injection”, US Patent
US Patent #5,560,737
Atomized Liquid Injection of biological processes covers a wide range of materials associated with in situ microbial treatment. The process involves the introduction of a liquid or slurry into a high velocity gas stream acting as a carrier fluid. The liquid is then atomized into a fine mist or aerosols and dispersed into the formation. Maintaining proper gas-to-liquid fed ratios result in the liquid being injected more uniformly and radially further than conventional hydraulic injection processes. Biological supplements such as vegetable oils, ORC® and HRC® can be injected using this technology.
“Dry Media Injection”, US Patent
US Patent #5,908,267
In the early to mid-1990s, ARS engineers working with NJIT researchers expanded the field of gas-based injection technologies to include dry media injection of materials. The initial fieldwork was performed at the DOE Hanford Site in Washington. Under this DOE funded project, dry media injection technology was used to emplace glass-frit (graphite) into the subsurface to serve as a conductive material for in situ vitrification. Since that groundbreaking project, dry media has been used to inject a wide variety of materials including ceramic beads and iron powder.
“Sonic Energy”, US Patent
US Patent #5,984,578
This new process under development by NJIT relies on the use of Sonic or ultrasonic energy as an enhancement tool to extract contaminates more effectively from the subsurface. When integrated with Soil Vapor Extraction (SVE), the technology relies upon the “excitation” of the target hazardous compounds, which in turn readily volatilize into the extraction airflow. Preliminary field treatability tests show favorable results for this new technology.
Pneumatic Fracturing, US Patent
US Patent #5,032,042
Pneumatic Fracturing (PF) can best be described as a process whereby a gas is injected into the subsurface at pressures exceeding the natural in situ pressures in the soil/rock interface (i.e. overburden pressure, cohesive stresses, etc.) and at flow volumes exceeding the natural permeability of the formation.
ZVI Soil Purification, Japanese Patent
Japanese Patent JP3267873 B2
Developed by ARS, this in situ treatment process for contaminated soil and groundwater is based on a gas injection process technology and has been demonstrated to treat a wide range of hazardous compounds including halogenated hydrocarbons, heavy metals, PCBs and pesticides.
Hybrid Fracturing (Patent pending)
An innovative in situ remedial technique termed “Hybrid Fracturing” has been developed and implemented by ARS Technologies to alter geologic conditions within the subsurface area below ground which allows for introduction of inert, non-reactive and reactive materials within such subsurface zone.
The Hybrid Fracturing (HF) technique incorporates the benefits of two proven remedial technologies consisting of Pneumatic and Hydraulic Fracturing processes. The techniques and capabilities of these two processes have been integrated into one streamlined process to further enhance permeability in the subsurface.
