Wastewater Treatment: Overview, Types, Energy Consumption & Actual State in Lebanon with Proposal of Using Renewable Energy

Abstract

This paper provides an overview of Wastewater Treatment issue in Lebanon, past, present, and Future. The paper briefs the status of wastewater types adopted in the general study approved by Lebanese Government to cover the country at the level of design and implementation along with the relevant energy consumption. Accordingly, we shall consider that paper as a recapitulation on exerted efforts by both Government and Council of Development and Reconstruction (CDR) to reach reliable and sustainable wastewater network and wastewater treatment plants. The perspective that we intend as a conclusion is the potential of renewable energy exploitation and treated wastewater reuse assisting the path of autonomy of WWTP’s and improvement of the energy management in wastewater treatment based on the integration of renewable energy and biogas.
