SANITARY AND ENVIRONMENTAL ENGINEERING PLANTS

Providing theoretical and practical knowledge to design and manage the engineering plants for: 1) solid waste treatment and disposal, 2) gaseous effluent treatment, 3) wastewater treatment and reclamation.

Lectures. Discussion on the content of the lectures. Classroom exercises on sizing of reactors for wastewater, waste and air treatment with the aid of IT tools.
