    摘要: Method for the continuous thermal hydrolysis of sludges containing organic matter, said method comprising the steps of: simultaneously injecting pressurized steam (100) into said sludges and mixing said sludges with said steam by means of a dynamic mixer-injector (4) so as to obtain a single-phase mixture, conveying said single-phase mixture towards a tube reactor (4) under pressure and bringing about the plug flow of this mixture into said reactor for a retention time that is sufficient and at a temperature that is sufficient to enable the thermal hydrolysis of the organic matter present in said sludges, cooling said single-phase mixture at its exit from said tube reactor to a temperature enabling the subsequent digestion of the hydrolyzed organic matter that it contains, depressurizing said cooled single-phase mixture.

    摘要: A water or wastewater treatment process that includes a dissolved air flotation process for removing suspended solids from influent water or mixed liquor. In one process, the dissolved air flotation process is carried out in the absence of adding a co-agulant or a flocculant, but yet produces TSS removal efficiencies comparable to those achieved by conventional dissolved air flotation processes that employ a coagulant and a flocculant. In other processes, a coagulant and/or a flocculant is added directly to the mixing zone of a dissolved air flotation system or is added via a pressurized white water injection system. In another process, the use of a coagulant and a flocculant is useful in removing TSS and reducing the concentration of phosphorus in the water being treated.

    摘要: Method and installation of thermal hydrolysis of sludges implementing a group of thermal hydrolysis reactors (71,72,73,74) characterized in that it comprises successions of cycles, each of these successions of cycles being dedicated to one of said thermal hydrolysis reactors, each cycle comprising: a step a) for conveying a batch of non-preheated sludges to be treated into a thermal hydrolysis reactor (71,72,73,74), said step for conveying comprising the continuous passage of the sludges of said batch of sludges into a dynamic mixer (3) into which recovery steam is injected; a step b) for injecting live steam into said thermal hydrolysis reactor (71,72,73,74) containing said batch of sludges so as to increase the temperature and the pressure prevailing in this reactor; a step c) of thermal hydrolysis of the batch of sludges in the thermal hydrolysis reactor; a step d) for emptying the content of the batch of hydrolyzed sludges of said thermal hydrolysis reactor towards a recovery vessel (13), and for concomitant de-pressurizing of said reactor prompting the emission of recovery steam from the recovery vessel (13); the cycle starting points of the successions of cycles being staggered in time so that the steps a) of a succession of cycles are concomitant with the steps d) of another succession of cycles, the recovery steam emitted during the steps d) of a succession of cycles constituting the recovery steam injected during the steps a) of another succession of cycles.
