Investigation of the electric energy production technologies from renewable energy sources for sea water desalination by reverse osmosis

Abstract

This work focuses on the study of several topologies of a sea water reverse osmosis desalination unit powered by a hybrid renewable energy system, consists of photovoltaic panels, solar battery bank and small wind turbine. Initially, a conventional sea water reverse osmosis unit without energy recovery and powered by electricity from the main grid was experimentally studied. The nominal capacity of the desalination unit is 1.7 m³/day, contains one membrane module, one high pressure vessel, a centrifugal feed water pump powered by an AC motor with an installed nominal power of 1 kW and a positive displacement high pressure pump powered by an AC motor with an installed nominal power of 2.2 kW. The feed water was prepared in a feed water tank (1 m³) by NaCI solution with electrical conductivity of 35 mS/cm, typically isoosmotic with sea water. The specific energy consumption of the conventional unit was recorded to be 20 kWh/m³. Several modifications were made to the conventional desalina ...
