Effluents and harmful gases are the main wastes, which are produced in a fertiliser factory. Suitable mechanism for waste management are:

  • For control of gaseous pollutants combustion equipments are used which can be oxidised. The pollutants are exposed to a high temperature in the process. Air pollutants, such 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 a large solid surface area. Toxic and odoriferous compounds are efficiently removed by this process.
  •  Three options available for controlling the effluents are:
  • Control can take place at the point of generation within the factory.
  • Waste water can be pre-treated for discharge to municipal treatment systems.
  •  Waste water can be treated completely at the factory and either reused or discharged directly for receiving water.
