This work presents the design and the realization of an autonomous small scale brackish water reverse osmosis desalination unit powered by intermittent renewable energy source. Sizing of motor-pumps, desalination membrane, renewable energy source and measuring instruments is detailed and analyzed. Motor-pumps characterization allowed to study their performances for several operating points according...
This paper is focused on modeling and energy management of one particular type of Brackish Water Reverse Osmosis (BWRO) desalination unit: a small-scale unit installed in remote areas. This kind of system, involving several water subsystems (hydro-mechanical processes), is powered by an intermittent energy source (PV-Wind turbine) via a DC bus. Such an autonomous system is characterized by a hydraulic...
This paper studies a water and energy management strategy dedicated to an autonomous water desalination system fed by a hybrid (Photovoltaic (PV) and Wind) power generator without battery storage. RO technology is one of the most powerful processes used for desalination to provide fresh water. Accordingly, renewable energy can be used especially by means of hybrid (PV-wind) system. Taking into consideration...
In this paper, the authors investigate a systemic modeling of a small-scale Brackish Water Reverse Osmosis (BWRO) desalination unit. This unit is powered by hybrid renewable energy system (photovoltaic-wind) without battery storage. The RO desalination process includes several disciplinary fields such as mechanical, hydraulic, chemical and thermal domains. Therefore, a multidisciplinary approach is...
This paper presents the experimental results of an original control strategy for motor-pump implemented on a dSPACE controller board. The Power Field Oriented Control strategy developed in this paper is used to drive a motor-pump fed by intermittent renewable sources. This system is dedicated to autonomous applications for pumping or water desalination for remote areas without access to hydraulic...
This work deals with complex and typical problem in order to optimize both water and energy management for water pumping and desalination processes. This contribution aims at proposing a management strategy for a Brackish Water Reverse Osmosis (BWRO) desalination plant. This unit is powered by a hybrid source mixing photovoltaic and wind resources. The main objective of the developed strategy is to...
