Abstract: A method and system for removing at least dissolved hydrogen sulphide or another targeted constituent from a feedstock is provided wherein the targeted constituent has a gas: liquid equilibrium. In some embodiments, the method includes the steps of: contacting the feedstock in at least one stripping vessel with a stripping gas to produce a gas stream containing at least hydrogen sulphide gas; conveying the gas stream from the at least one stripping vessel to an oxidation reactor; contacting the gas stream with an oxidizing agent in the oxidation reactor so as to oxidize the at least hydrogen sulphide gas to produce sulphuric acid; and conveying the produced sulphuric acid from the oxidation reactor to the at least one stripping vessel so as to reduce a pH value of the feedstock within the stripping vessel.

Abstract: Method and system for treatment of a wastewater stream at a location is disclosed. The wastewater stream includes a floating waste component such as sewer FOG or oil and an aqueous component such as water. The wastewater stream is directed from the location to a separator through an intake which is fluidly connected to the location and the separator. The separator separates the floating waste component from the aqueous component. The separated floating waste component is directed to a floating waste discharge outlet associated with the separator and the separated aqueous component is directed to an aqueous discharge outlet associated with the separator.
