Research & Development

Although our patented technologies (SURFAC®, SOLV-IT®, and ISCO-EFR®) have proven to be effective and economical through numerous field implementations, our continuous effort to improve our technologies and develop new solutions does not cease.  EcoVac Services heavily invests in its research and development (R & D) department to improve existing remedial processes while also developing new technologies.  The following lists how we conduct our internal R & D:

  1. EcoVac Services utilizes its comprehensive in-house laboratory for development and validation of new technologies.  Our in-house laboratory allows us to experiment with new ideas that are independently generated by our staff, as well as those concepts derived from academic articles and scientific journals.  These experiments frequently are time-consuming “trial and error” events; however, our drive to create innovative and unique effective solutions propels our efforts.
  2. Each site-specific treatability study is considered part of our internal R & D.  Every treatability study is site-specific as each site has its own unique characteristics (e.g. the difference in lithology, type of contaminant, geochemistry, groundwater chemistry, etc). Therefore, it is critical for us to devise a distinctive answer to each site-specific problem.     
  3. EcoVac Services integrates each site-specific treatability study into a database.  The statistical database guides us in the direction of the necessary research as well as determines the most appropriate treatment train for a particular remedial event.     

Our current list of R & D includes:

  1. Continuous improvement and development of new surfactants and cosolvents / biosolvents,
  2. Development of in situ treatment trains for challenging contaminants such as coal tar, creosote, bunker fuel, and crude oil contaminated sites,
  3. Development of in situ treatment trains for sites impacted by heavy metals.

Our progress on the above includes:

  1. EcoVac Services has devised Winsor Type III systems with unique site-specific surfactant blends (EFSTM) that allow superior hydrocarbon recovery. 
  2. EcoVac Services has devised EFCTM, a unique blend of vegetable solvent and nonionic surfactants.  EFCTM is stable in both aqueous and non-aqueous phases.  EFCTM has achieved more than 95% removal of viscous coal tar (1,000 – 2,500 cps at 77 °F) from sand packed column. 
  3. Treatment trains for coal tar, creosote, bunker fuel, and crude oil has been developed with combinations of EFR®, SOLV-IT®, and SURFAC®.  This new treatment train may offer effective and economical alternative to conventional treatment trains.
