The aim of the present work is to establish a systematic approach in the range of characterization of commercial nanofiltration (NF) and low pressure reverse osmosis (LPRO) membranes materials for a better help to the users. We developed two sorts of characterizations: (i) first physico-chemicals in

An economic study was conducted to evaluate the costs of fluoride removal by electrodialysis on the basis of industrial and economic data. The investment and operating costs were estimated for an industrial plant with a capacity of 2200 m3/d water consumption for 50,000 per capita according to Moroc

Studies have been performed on removal of fluoride from Moroccan groundwater by electrodialysis in continuous operation using a pilot plant. The performances of two anion exchange membranes were compared. An optimisation of electrodialysis operation was carried out for various experimental condition

Good characterization of raw water quality and subsequent identification of the most appropriate pre-treatment are not sufficient to ensure successful functioning of a reverse osmosis plant. The Tan Tan demineralization plant was set up in July 2003 for 20 l/s production capacity. The brackish water

Studies have been conduced on a groundwater containing 850–1100 mg/l of total dissolved solids (TDS) and 80 mg/l of nitrate to remove nitrate by coupling electrodialysis and bioreactor. The performances of the pilot plant during the period of the tests (more than one year) were proved. The optimisat

Conventional water resources meant for drinking water supply in Morocco’s Southern Provinces are very scarce. In order to offset this shortage the National Office for Potable Water (ONEP) entrusted with potable water planning and production in Morocco, has since 1975 resorted to the development of n
