Reverse osmosis is the most widely used desalination technology for treating irrigation water. removes both monovalent ions detrimental to crops (Na+,Cl?) and divalent beneficial (Ca2+,Mg2+,SO42?). Fertilizer must then be added desalinated water reintroduce these nutrients. Unlike reverse osmosis, selective electrodialysis selectively while retaining in This paper investigates selectivity cost ...
Comparison of fouling propensity between reverse osmosis, forward osmosis, and membrane distillation
Direct Osmosis for Reverse Osmosis Fouling Control: Principles, Applications and Recent Developments
BACKGROUND The bacterial and chemical contamination of dialysate fluids are important problems in haemodialysis therapy and may be caused by the water used for dialysate preparation. METHODS We performed a survey of the microbiological and chemical quality of the water used in seven dialysis wards. Special attention was paid to the effects of each water treatment step, for example ion exchang...
