29098 - Environmental Technologies L

Learning outcomes

The purpose of this course is to present the main operations for wastewater and polluted air treatment. The basis working principles of each process are discussed and simple quantitative methods of study of selected apparatus and plants are covered.

The goal is to provide the students with basic tools for understanding and making previsions about the main operations adopted for environmental applications as well as with the main features of typical equipment of wastewater and polluted air treatments plants.

Course contents

1. Air Pollution Treatments. Principles, working characteristics and design elements relevant to the following operations: dust removal by settling chambers, cyclones, bag filters, electrostatic precipitators, scrubbers; vapour and gas compound removal by chemical absorption, VOC incineration, condensation.
2. Wastewater treatments. Main operations in domestic and industrial effluents treatment plants. Principles, working characteristics and design elements relevant to the following operations: physical treatments, chemical treatments, solid-liquid separations, biological treatments. Sludge handling.
