  • Publication number: 20240279087
    Abstract: A system may include an agitation and mixing subsystem, the agitation and mixing subsystem configured to agitate the aqueous stream and mix the aqueous stream with the anhydrite quantity such that the anhydrite quantity interacts with negatively charged contaminants to form one or more precipitate complexes, which comprise a calcium cation and a negatively charged contaminant, in the aqueous stream. A system may include an electro-coagulation and/or electro-oxidation subsystem configured to receive the aqueous stream comprising the one or more precipitate complexes, the electro-coagulation and/or electro-oxidation subsystem comprising aluminum-containing or titanium-containing electrodes that are configured, when a voltage is applied, to yield hydroxyl ions in the aqueous stream comprising the one or more precipitate complexes.

  • Publication number: 20210276886
    Abstract: The quick response system and method for removing volatile compounds from contaminated water disclosed herein may comprise, at least, a preconditioning stage, a stripping stage, a condenser stage, a refrigeration stage, and a scrubber stage. The present invention relates to a portable system and method that can be deployed on an emergency or quick response basis to purify aqueous streams containing volatile organic compounds (VOC) and chlorinated hydrocarbons, collectively volatile compounds (VC), emitted from petroleum and chemical processing facilities. The system allows manufacturing facilities having internal cleanup issues to become compliant with environmental standards and guidelines quickly. Once the issue in the petroleum facility are fixed, this method can be demobilized and removed from the site in a short period of time.
