SRS™ Specifications-FracturedRock

Terra Systems, Inc. SRS-FR™ Emulsified Vegetable Oil (EVO) Substrate for Fractured Rock Formations United States Patent No. RE,40448 The anaerobic bioremediation process uses either native or introduced microorganisms to degrade chlorinated solvents such as tetrachloroethene (PCE) and trichloroethene (TCE) to innocuous end products including ethene and ethane. An organic substrate must be added to the groundwater to generate reducing conditions and provide the necessary carbon and hydrogen to support biodegradation of the chlorinated solvents. The organic substrate can be a slow release substrate like Terra Systems’ SRS™ emulsified vegetable oil substrate. SRS-FR™ is designed to release bio-available hydrogen over a period of 3 to 5 years thus enhancing the long-term anaerobic biodegradation of the chlorinated solvents. SRS-FR™ optimizes the naturally occurring biodegradation system by supplying the rate limiting factor (in this case hydrogen) in the degradation of VOC’s, certain pesticides/herbicides, perchlorate, and immobilization of certain metals (Cr, As, and some radionucleides). SRS-FR™ Substrate Specifications Terra Systems, Inc.’s manufacturing facility is configured to allow us to provide our customers with custom blended substrate packages without a cost premium. The basic SRS-FR™ package contains the following components: Ingredient CAS # Percent Hazardous Food grade edible oil, emulsifiers and proprietary nutrient package containing nitrogen, phosphorus and vitamin B12 Mixture 50-70 No Sodium Lactate 72-17-3 <5 Yes Water 7732-18-5 30-50 No KEY BENEFITS OF SRS-FR™ Emulsified Vegetable Oil (EVO) Substrate Include: ? Promotes biodegradation of PCE and TCE to non-toxic end products ? Large droplet size is ideal for maximum adherence in a fractured rock formation ? Low cost ? In situ vs. Ex situ application minimizes site disruptions ? Slow release formula eliminates continuous substrate additions ? SRS-FR™ contains only non-toxic food grade materials, which results in green, sustainable remediation ? Can be used as a PRB to cuts off plume migration ? Effective in source zones ? Reduces treatment time from decades to months and years The standard SRS™ droplet has a mean size of 0.6 microns, which is designed for maximum radius of influence. However at sites with fractured rock formations, it is sometimes more appropriate to use a larger droplet size to increase the probability of the droplet attaching to the rock surface. Terra Systems SRS-FR™ substrate package has a mean droplet size of 5.0 microns, which improves the probability of adherence to the formation. Terra Systems, Inc. has applied this technology at military bases and manufacturing sites throughout the USA and in South America and Asia. Some of the sites where the FRS technology has been demonstrated include the northern New Jersey, Pennsylvania, North Carolina and Tennessee.
