Development of boron reduction system for sea water desalination

Enhancement of boron removal in treatment of spent rinse from a plating operation using RO

“…The common advantage of removing boron effectively by means of increasing the feed pH in the second stage [3,8] or in the third stage [6] mentioned above was that the membrane fouling caused by the precipitation of the calcium and magnesium salts could be avoided due to low concentration of these salts in the feed. However, an extra cost in terms of capital investment and chemical consumption would be involved in the additional stage [3,6,8].…”

“…Conventional methods for boron removal are ion exchange [4] and flocculation/precipitation [5], which is expensive. Advanced reverse osmosis (RO) membrane technology has become increasingly attractive for boron removal in the treatment of water and wastewater in various applications [3,[6][7][8][9][10][11] as it is highly efficient, easy and economical to operate. Magara et al [6] developed a multi-stage RO membrane system for boron reduction in the production of drinking water from seawater desalination.…”

Ceramic Membranes in Removing Boron from Processed Geothermal Waters

“…Male reproductive impediments of laboratory animals were affected by boron ingredients [1][2][3][4]. Boron was categorized as a pollutant in drinking water by European Union (EU).…”

Aplicaciones estratégicas de la Nanofiltración para el tratamiento de las aguas en la industria cerámica

“…La mayor parte del boro encontrado en la tierra se encuentra en los océanos y en depósitos continentales naturales [24].…”

“…La membrana usada en este caso ha sido la ES10-D4 y las características de la disolución empleada en el ensayo han sido de un pH de 10 y una concentración de boro de 1 mg/L [24].…”
