Method and System for Electrochemically Remediating Contaminants in a Liquid

An electrochemical contaminant remediation system comprising:

• a conditioning tank including an untreated liquid input and a conditioning agent input, the conditioning tank being configured to accept untreated liquid comprising a water-soluble contaminant from the untreated liquid input and conditioning agent from the conditioning agent input such that the untreated liquid and the conditioning agent are combined in the conditioning tank to form a conditioned solution in the conditioning tank, the conditioned solution having a substantially neutral colloidal charge;
• a conditioned fluid flow path fluidly connecting the conditioning tank to a flow-through electrochemical reactor, the conditioned fluid flow path being configured to accept the conditioned solution from the conditioning tank and to deliver the conditioned solution to the flow-through electrochemical reactor, the flow-through electrochemical reactor comprising:
• a housing including an internal liquid flow-path;
• a first electrode disposed within the internal liquid flow-path;
• a second electrode spaced apart from the first electrode creating an electroactive gap between the first electrode and the second electrode, the flow-through electrode being configured to pass the conditioned solution through the electroactive gap and thereby electrochemically remediate the water-soluble contaminant.

An electrochemical contaminant remediation system comprising:

• a reactor tank, the reactor tank including an untreated liquid input for accepting an untreated liquid comprising a water-soluble contaminant, a conditioning agent input fluidly connected to the reactor tank by a conditioning agent fluid flow path, the reactor tank being configured to accept untreated liquid comprising a water-soluble contaminant from the untreated liquid input and conditioning agent from the conditioning agent input such that the untreated liquid and the conditioning agent are combined in situ in the reactor tank to form a conditioned solution, the conditioned solution having a substantially neutral colloidal charge;
• and
• a flow-through electrochemical reactor comprising:
• a housing including an internal liquid flow-path;
• a first electrode disposed within the internal liquid flow-path;
• a second electrode spaced apart from the first electrode creating an electroactive gap between the first electrode and the second electrode;
• and the flow-through electrode being configured to pass the conditioned solution through the electroactive gap and thereby electrochemically remediate the water-soluble contaminant.
