摘要
A procedure for producing a liquid fertilizing product from a biosolids cake that has been de-watered to a biosolids content of 18% or more. The procedure includes positioning a process amount of the biosolids cake in a reactor vessel, heating the biosolids cake process amount, and adding a quantity of an alkali and mixing it into the process amount of the biosolids cake to form a reactor mixture. The reactor mixture incubated for a period, and then cooled. The alkali includes pH-raising and hydrolysis-procuring components. The quantity of alkali in relating to the biosolids process amount is sufficient that a residual amount of the alkali remains in the cooled reactor mixture, the pH of the reactor mixture remains at a saturation level during and after the incubation period, and the cooled reaction mixture is pumpable.
