Question

Incineration is a “Cold treatment” process.

(a) True

(b) False

The question was asked by my school principal while I was bunking the class.

Origin of the question is Disposal of Effluent topic in chapter Effluent Treatment of Bioprocess Engineering

Answer 1

Correct answer is (b) False

For explanation I would say: Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration and other high-temperature waste treatment systems are described as “thermal treatment”. Incineration of waste materials converts the waste into ash, flue gas and heat. The ash is mostly formed by the inorganic constituents of the waste, and may take the form of solid lumps or particulates carried by the flue gas. The flue gases must be cleaned of gaseous and particulate pollutants before they are dispersed into the atmosphere. In some cases, the heat generated by incineration can be used to generate electric power.
