FIELD: separation of solid and liquid phases from material. SUBSTANCE: when use is made of filter presses with periodic operating duty, further rise of compression duty is limited on the basis of the characteristic of discharge of compressed liquid, depending on time. Moments of limitation time are determined by means of a processor, during which instantaneous or overaged discharge power or acceleration of discharge of liquid phase attains its maximum value. Thus, it becomes possible to avoid introduction of preset values or experimental values, which cause interference. This press itself during one process carries out self-optimization of compression pressure and time periods, within which the rise of pressure should be limited with respect to the direct process parameters. EFFECT: optimized process. 7 cl, 9 dwg
