The RSB-7 collection system treatment strategy was enacted on a sewer segment processing two million gallons per day to decrease H2S emissions and FOG buildup. We contrasted the impact of treatment with untreated conditions and presented the findings below.

RPS Environmental Solutions LP engaged a remedial efficacy test of its Remedia™ Hydrocarbon Stabilizer product in an effort to prove its efficiency regarding Insitu Remediation treatment of TPH in soil substrates.
Conclusion:
Hydrocarbon Reduction 45% to 75%
Pre Treatment TPH Range 32,400 mg/kg to 653 mg/kg
Post Treatment Confirmatory TPH Results 18,000 mg/kg to 160 mg/kg
Our technology was successfully and cost-effectively employed to remediate an oil refinery’s waste sludge. TPH reduction percentages were 48% and similar results were achieved from sludge contaminated soil where TPH was reduced by 45%, which significantly reduced the cost for treatment.

Our technology has successfully remediated gasoline in water. After gradual addition and mixing of our product to the gasoline and water mixture, with aeration and agitation, a 98% reduction in BTEX (34 ppm) was achieved. Since the level of Benzene measured less than 0.5 ppm, the treated liquid was pumped and discharged into the city waste treatment facility by city employees.

A study involving semi-volatile organic compounds and diesel indicated that the use of our technology shows an average decline of 59% for the semi-volatile compounds and 68% reduction of the diesel. The study further showed that the mobilities of selected organic compounds are effectively reduced when treated with our product.

Our technology remediates petroleum hydrocarbons significantly faster than microbial treatments. Treatment stabilization using our product shortened job completion by at least six weeks with a reduction in treatment costs of approximately $122 per yard3.

PCBs in Transformers can be successfully remediated with our technology. In one particular treatment, results revealed a decline from the original concentration of 920,000 ppm PCB to an average of 5,665 ppm PCB in the gel layer — a reduction of 99%. Only a residual percentage of 83 ppm remained in the aqueous phase.

Our technology was extremely effective at a crude oil spill. A single application at a rate of 2.5 gallons per yard3 reduced hydrocarbon petroleum leachability by 72% to satisfy minimum standards. No soil removal or further treatment was required.

Soil (sludge) contaminated with creosote was treated with our product and aerated (turned) daily for five days prior to lab analysis. Results showed a 77% reduction of the lower MW PAH compounds and a 20% reduction in higher MW PAH compounds. Similar results with bioremediation would likely have taken 9-12 months.
At a drilling yard, our technology was used to reduce TPH in soil. A Phase II report on the property revealed an average of 6000 ppm TPH in 490 yard3 of soil. After our product was applied, a reduction to 138-120 ppm TPH was shown in just five days. Further reduction (with no further treatment) showed results down to 23-10 ppm after 27 days.
Continue readingEPA/DfE recognition does not constitute endorsement of our products. The Design for the Environment logo signifies that the formulas for our products, as we have represented to the EPA, contain ingredients with more positive health and environmental characteristics than conventional products. EPA/DfE relies solely on our integrity and good faith for information on the composition, ingredients, and attributes of our products. EPA/DfE has not independently identified, i.e., via chemical analysis, the ingredients in our products, nor evaluated any of the non-ingredient claims we have made. EPA/DfE expresses its judgment and professional opinion only as to the environmental and human health characteristics of our products, based on currently available information and scientific understanding.
Solterra™ is the only complete line of cleaning, remediation and odor elimination products to be recognized for safer chemistry by the EPA’s Design for the Environment (DfE) program. Solterra™ products were found worthy of recognition after passing a rigorous third party toxicology review and an EPA scientific review. For the DfE label, Solterra™ partners with the EPA to maintain the highest standards of product safety.
What is the Design for Environment Program?
Design for the Environment (DfE) works with environmental organizations and industry to protect human health and promote sustainable chemistry. DfE’s Safer Product Labeling Program helps to protect families and the environment by distinguishing household cleaning products, like soaps, detergents, and cleaners that are safer for people and the planet. The EPA’s scientific team rigorously evaluates each product for its impact on both human and environmental health.
What Does the DfE Label Mean?
EPA allows safe products to carry the Design for the Environment (DfE) label. When products carry the DfE label it means a scientific review team has screened each ingredient for potential human health and environmental effects and that—based on currently available information, EPA predictive models, and expert judgment—the product contains only those ingredients that pose the least concern among chemicals in their class.
