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

Explanation

Effluents and harmful gases are the major pollutants which are generated in a fertiliser, chemical or pesticides factory. Scientific mechanism for reduction in emission of pollutants in
environment is :
For reduction of gaseous pollutants, electro-static precipitators (ESP) are commonly used. ESP works on the principle of opposite charges attract.
When the gaseous emissions containing unburnt pollutants such as coal particles, unburnt carbon, SOX, NOX, etc. enters this field, ash particles gets charged and attracted towards the collecting plates due to the force produced by the electric field. Thereby, reducing the gaseous emissions in the atmosphere.
In addition to this, industrial waste water generated from the fertiliser industry contains pollutants that may contaminate our natural water resources. For safe disposal of industrial waste water, effluent treatment plant (ETP) is set up to treat the waste water. An ETP is used to purify water and remove any toxic and non-toxic materials or chemicals from it. They use evaporation and drying methods, and other auxiliary techniques such as centrifuging, filtration, incineration for chemical processing and effluent treatment. The treated water can be used in the industrial process and for irrigation of plantation.
