Framgangsmate for a redusere vaeskemengde i biologisk masse

Den foreliggende oppfinnelse vedrører et system (1) for å redusere væskemengden i biologisk masse som omfatter faststoff og fluid, hvor systemet (1) innbefatter et separeringsapparat (3, 3') innrettet til å kunne separere i det minste en andel av massens fluid fra massens faststoff, hvor systemet (1) videre innbefatter en væskerenseinnretning (21). Oppfinnelsen vedrører også en framgangsmåte ved bruk av systemet (1). The present invention is directed toward a method and a system for reducing the amount of fluid in a biological mass comprising solids and fluid in the form of liquid and gas. The system includes a temporary storage container for receiving and temporary storing a biological mass, at least one separator arranged to receive the biological mass from the temporary storage container and separate at least a portion of the fluid of the mass from the solids of the mass, a solids container for receiving the solids fraction separated from the biological mass, and a liquid-purifying device arranged to purify the liquid which is separated from the mass by means of the separator. The system is substantially fluidtight towards the surroundings and the separator includes a screen cloth and a device for inducing a fluid flow. The fluid flow is arranged to carry a portion of the liquid out of the mass and through the screen cloth, the essential part of the fluid flow has been recirculated in the system (1).
