Abstract

Aqueous effluent treatment system including a separation reactor having a reactor chamber fluidly connected to an aqueous effluent source, connected via a pump to an inlet of the reactor chamber, a fluid extraction system connected to a liquid effluent outlet at a top of the reactor chamber, and a solid residue extraction system connected to a solid residue outlet at a bottom of the reactor chamber. The separation reactor is operable to generate pressures exceeding 22 MPa and temperatures exceeding 300° C. in the reactor chamber configured to generate a supercritical zone in an upper portion of the reactor chamber to which the liquid effluent outlet is connected, and a subcritical zone in a lower portion of the chamber within the reactor chamber to which the solid residue outlet is connected. The solid residue extraction system comprises an output circuit comprising a collector coupled to the solid residue outlet via a collector input valve (V1) and to a water output tank via a filter and a collector liquid output valve (V4) operable to be opened to cause a pressure drop at the solid residue outlet to draw solid residue out of the reactor chamber, the solid residue extraction system further comprising a gas feed circuit connected via a gas supply valve (V5) to the collector, the gas supply valve operable to be opened to extract solid residues in the collector to a solids output tank connected to the collector via a collector solids output valve (V6).
