Suggest suitable mechanism(s) for waste management in fertilier industries.

Explanation

Effluents and harmfull gases are the main wastes which are produced in a fertiliser factory.
Suitable mechanism for waste management are
(i) For control of gaseous pollutants combustion equipments are used for pollutants which can be oxidised. The pollutants are exposed to a high temperature `(1650^(@))` in the process.
Air pollutants sauch as certain gases and vapour and inflammable compounds are controlled through the use of adsorption equipments. Adsorption is a surface phenomenon and it needs the presence of solid surface area. Toxic and odoriferous compounds are efficiently removed.
(ii) Three options are available for controlling the effluents
(a) Control can take place at the point of generation within the factory.
(b) Waste water can be pre-treated for discharge to municipal treatment systems.
(c) Waste water can be treated completely at the factory and either reused or discharged directly into receiving waters.
