Abstract
Waste gases are found in all branches of industries. As long as the contents of organic or inorganic substances are below local admissible values the waste gas may be released to the environment without any additional treatment. If these specific values are higher the waste air shall be treated before leaving the plant site. Clearly gaseous wastes are difficult to store; therefore most of the waste must be cleaned in place where it is generated mostly by fast chemical absorption, adsorption or incineration (see Chapter 2). Industries like to be flexible in producing products. Therefore variable waste production may also be observed. All biological waste gas systems are extremely well suited for constant gas loads and constant waste composition which is not the standard case. Normally the loads and contents of organic by-product in waste gases is changing within short periods of time. This explains why only few systems are incorporated in industrial applications. However, many different approaches have been attempted to overcome the load fluctuations.
