Odour Control
Introduction
Biofiltration
uses micro-organisms to remove undesirable components from
industrial waste gases. Waste gases are forced though filter
material on which micro-organisms are immobilized. After absorption
in the filter material, micro-organisms break down the polluting
components and transform them into harmless products such
as carbon dioxide, mineral salts or acids and water.
