Life cycle assessment of an industrial-scale petrochemical wastewater treatment plant

Petrochemical industries produce a huge amount of wastewater during the production of various petrochemical products. The generated wastewater must be properly treated before being released into the environment because it contains harmful chemical compounds that affect human health, the aquatic ecos...
