Abstract: A salt separator separates salts and/or solid materials from a pumpable aqueous fluid mixture under process conditions, which lie in the range of the critical point for the fluid mixture. The salt separator contains a reaction zone in a cavity for transforming the pumpable aqueous fluid mixture into a raw mixture, e.g. a methanation reaction, and a feed opening for the pumpable aqueous fluid mixture to the cavity. The feed opening is realized in a rising pipe that protrudes into the cavity. A first extraction opening is provided for the raw mixture freed of salts and/or solid materials. The first extraction opening is arranged in the upper region of the cavity and a second extraction opening is provided for a brine containing the salt and/or the solid materials.

Abstract: In accordance with one aspect of the invention a testing procedure, a processing procedure and a resulting product are provided whereby sewage sludge is primarily or firstly pre-hydrolysed in whole or in part by means other than alkali. The alkali is then added to the pre-hydrolysed product. The pre-hydrolysed product from step one has a reduced potential for further hydrolysis and is more effectively stabilized in step 2 as a liquid biosolids-containing product or BSP. As a result, in accordance with the invention less of the alkali is used up in the step 2 further alkali-based hydrolysis of the pre-hydrolysed product. The pH of the BSP product after the step 2 alkali treatment drops less over the period of storage and the BSP product will be better preserved against microbial regrowth.
