Claim Text:
1. A system for treatment of wastewater, comprising: a wastewater feed port configured to receive an incoming stream of wastewater; an electro-oxidation module configured to receive an incoming wastewater stream and facilitate precipitation of one of more contaminants from the wastewater stream passing therethrough; an electrocoagulation module comprising at least two electrodes, wherein the electrocoagulation module is configured to receive an incoming wastewater stream and remove one or more contaminants from the wastewater stream passing therethrough; a flotation module configured to receive and separate an incoming wastewater stream into an aqueous phase stream and at least one of an oil phase stream and a sludge phase stream; an evaporation module configured to receive the aqueous phase stream from the flotation module and further configured to remove scale-forming elements within the aqueous phase stream; an ultrafiltration module configured to receive an incoming stream, remove precipitated solids formed by the evaporation module, and deliver an outgoing stream of permeate comprising a salt solution; and a detection module configured to detect a pH of the wastewater before the wastewater enters the electro-oxidation module, wherein the system is configured to disable at least one of the electro-oxidation module and the electrocoagulation module or divert the wastewater stream to avoid at least one of the electro-oxidation module and the electrocoagulation module upon detecting a threshold pH of wastewater before the wastewater enters the electro-oxidation module.
