O-SOX ™
Applications
Applications for O-SOX include
- Oxygen releasing compound in a sock for aerobic bioremediation in ground water wells.
- Easiest deployment of dissolved oxygen.
- Stimulation of aerobic biodegradation of groundwater contaminants through controlled release oxygen and nutrient delivery using EHC-O. This is not an aggresive treatment but, rather, an enhancement to natural attenuation. Ideal for sites where there are residual or thin layer of contaminants.
- The radius of influence depends on the hydrogeology of the site but is still predictably small (in the order of 10 ft radially, 20-50 ft downgradient)
O-SOX Sleeves and stainless steel canister in 2" and 4" sizes. Socks are stored and shipped in pails.
- Easiest deployment of dissolved oxygen.
- Enhances Natural Attenuation
- > 50% Less Expensive
- Easy and quick delivery system for groundwater wells
- Long Lasting
- Petroleum hydrocarbons
- PAHs
- Other non-halogenated organic compounds
Description
EHC-O is an integrated source of slow-release oxygen combined with nutrients and a pH buffering agent to provide the ideal conditions for rapid bioremediation of organic and inorganic soil, sediment and groundwater contaminants. For organic constituents, EHC-O significantly stimulates catabolic activity of indigenous microflora further accelerating the rate of contaminant removal. EHC-O not only eliminates contaminants quickly —but also guarantees appreciable cost savings over other oxygenrelease products on the market. EHC-O’s proprietary technology is field proven and available today.
O-SOX is a delivery mechanism consisting of a fabric sleeve (or sock) filled with EHC-O and a stainless steel canister. For ease of use in groundwater wells, the socks are lowered in the well inside reusable stainless steel canisters. The number of canisters that can be hooked together is limited and governed by well screen length, weight, and the fact that they all need to be submerged.
O-SOX is available in two nominal sizes: 2 x 36 in and 4 x 36 in.

Instructions
Take a sock from the pail and remove plastic sleeve.
Insert sock into canister.
If desired, attach an optional canister and insert a sock.
Adjust the length of cable required.
Lower canister in the well.
Cap rests on top of casing.

FAQs
EHC-O O-Sox contain a well-buffered source of controlled release oxygen plus inorganic nutrients (mainly nitrogen) that can accelerate the biodegradation of various organic compounds and enhance certain natural attenuation processes. In addition, the O-Sox technology is a practical stainless steel canister and sleeve system which greatly simplifies and hastens installation, removal and replacement.
In most cases, the naturally occurring (indigenous) microorganisms are well adapted to the organic constituents of interest and inoculants are not required.
The rate and extent of removal of all organic compounds that are biodegraded under aerobic conditions are usually enhanced via the addition of oxygen and inorganic nutrients. Petroleum-based aromatic (e.g., benzene, toluene, xylene, phenol) and aliphatic hydrocarbon mixtures (e.g., gasoline, heating oil, Diesel fuel, jet fuel, kerosene) are primarily targets; lightly chlorinated ethenes (vinyl chloride), MTBE, dioxane, pentachlorophenol, and many other compounds are also potentially amenable to O-Sox treatment
O-Sox cost about 25% less than market alternatives.
It’s a better product. And the superior design and ease of application will immediately translate into greatly reduced field time and frustration = reduced project cost.
Yes. EHC-O has been accepted by many state regulatory authorities and it has been employed throughout the USA and Europe. For example, see: EHC Acceptance Letter - Innovative Technologies Florida Department of Environmental Protection.
No. The O-Sox technology is designed to fit into standard 2-inch and 4-inch diameter groundwater monitoring wells. The canisters have a nominal outside diameter of 1.75 inches for the 2-inch size and 3.5-inches for the 4-inch size.
The rated delivery is at least 15 lb of oxygen per 100 lb of EHC-O, after 200 days.
Yes, about 3 to 4 months in dry storage at room temperature.
Yes, about 3 to 4 months in dry storage at room temperature.
All O-Sox must be placed below the groundwater table and they should be within the screened interval. The wet weight of each 2-inch and 4-inch O-Sox unit (3-ft long canister and sleeve) is about 5 and 16 lbs, respectively. We therefore recommend a maximum linkage of five 2-inch diameter systems (15 ft screened interval; 25 lbs) or three 4-inch diameter systems (9 ft screened interval; 48 lbs). Up to three sets of linked O-Sox units can be used for wells with longer screen lengths.
