The proposed research project aims to overcome challenges that address operation, design, and utilization of an**electrical Power Supply Unit (PSU) used in a Water Treatment System (WTS). The targeted WTS uses**ElectroDialyses Reversal (EDR) technology. The EDR process removes unwanted dissolved ions by passing**electric currents in the flowing water. For wastewater with moderate concentrations of dissolved ions, EDR is**an excellent option for achieving superior treated water quality. EDR is an advanced membrane technology**process that utilizes ion movement to desalinate water. EDR systems are rugged, with very long membrane life**and require significantly less pretreatment than spiral wound membranes while having the ability to achieve**very high water recoveries. EDR is a chemical-free treatment process that uses electro-separation method to**remove ionic salts from water. EDR enables a self-cleaning cells system, because of the voltage-polarity**reversal design. Using the EDR technology, wastewater or seawater can be treated and reclaimed for irrigation**and drinking water purposes, with up to 94% water recovery.**The proposed research project objective is to achieve a reliable, safe-to-operate and cost-effective EDR-WTS.**Classically, EDR-WTS are supplied by multiple, identical and independent PSUs, which can be bulky and**expensive. This research project aims also at developing a new innovative, cost-effective, and reliable Power**Supply Unit, by using a multi-output power converter technology, while achieving high quality line current**with less interference. The innovative PSU will be controlled to independently drive up to four EDR cells with**a reverse voltage-polarity capability. A full study and simulation will be completed as to develop a prototype**that should lead to a new product for water purification and desalination systems. The proposed technique shall**be developed in-house, in Montreal, and the PSU is expected to allow Suez to reduce expenses from acquiring**PSU technologies from other suppliers, which are usually imported from manufacturers abroad. the project will
