Lesson 5: Waste Processing and Separation



Objective: Describe the most common waste processing techniques and their application.

Goals:



Introduction

Material Separation Location


Unit Operations for Processing

Compacting

Size reduction


Material Separation

Separation Prosesses
Rotary Trommel Screens

Air classfication (Float/Sink separator)

  • Major MSW unit process (2nd to magnetic)
  • current of air used to effect material separation based on density, viscous drag.
  • Separates less dense, mostly organic materials from more dense, mostly inorganic fraction.

  • Mechanical Separation Techniques for Specific Materials
