Abstract:
A process for the aerobic treatment in a biosolids treatment reactor of a biosolids solution comprising the products of waste water treatment and thermophilic bacteria capable of digesting mesophilic bacteria, said process comprising:(a) mixing a portion of the biosolids solution with an oxygen-containing gas stream using a jet aeration device;(b) injecting a mixture of the oxygen-containing gas and biosolids solution into the reactor at a flow rate which introduces sufficient oxygen into the biosolids solution so that the treatment environment is substantially constantly aerobic;(c) monitoring at least one physical property of the biosolids solution during aerobic thermophilic autothermal digestion of the biosolids solution; and(d) adjusting at least one physical property of the biosolids solution during aerobic thermophilic autothermal digestion of the biosolids solution by adjusting the mixing of biosolids solution with the oxygen-containing gas stream.
