Abstract

In this paper the analysis and description of the operation of the Premix station for dosing the substrate into existing digesters whose location is in the system of the device for processing of liquid waste are described. Apart from the capacity and other entry parameters, the necessary diameter of the pipeline with the length of the section for supplying the devices of the PreMix system is calculated, as it is given in the appropriate tables, the connection of the existing equipment and digesters is presented. The appropriate dependence of the volume flow, the velocity of circulation and power at constant pressure as well as the dependence of the volume flow, pressure and power at constant velocity of circulation are presented by diagrams.

Highlights

  • PREMIX system serves to cut up the broad spectrum of biomass into homogeneous organic suspension, it separates the heavy material and cuts up solids into small pieces before they go into the pump unit

  • The power of PreMix is the mixing of different solids with liquid in order for us to form the homogenous organic suspension which is suitable for decomposition with anaerobic bacteria

  • After the biomass is brought into the filling of solids by worm gear conveyor, the first step is separating of heavy materials

Summary

Introduction

PREMIX system serves to cut up the broad spectrum of biomass into homogeneous organic suspension, it separates the heavy material and cuts up solids into small pieces before they go into the pump unit. With the help of only one Remix, it is easy to feed several digesters and enable simple and fast service immediately. Rough particles and fibrous matter too, are cut up into small pieces This concept does not allow the damage which is made because of pebbles, metal parts and other heavy materials and makes sure that biomass is prepared accurately for decomposition [4,5,6]. Thanks to the compact design, a small space of few square meters is enough for the position of PreMix, including a space for service and maintenance [7, 8].
