Abstract
"MóDULO DE FILTRAçãO DE MúLTIPLAS MEMBRANAS". O módulo de filtração de múltiplas membranas de fibras ócas de osmosis reversa ou nano-filtração são suspensas entre um par de cabeçotes opostos. As concavidades das membranas estão do lado do retendido ou do lado do afluente. As membranas são arranjadas em grupos, tal um setor de um cilindro e formam estágios anteriores e posteriores. O espaço de coleta do permeado está em comunicação hidráulica direta com cada estágio. Os estágios são conectados por meio de tampas, com divisores localizados às extremidades do módulo. O módulo é utilizado para filtrar a água, facultativamente com membranas de fibras ócas adaptadas para rejeitar a dureza causada pelos sais e é pois utilizado para remover a dureza. Métodos de limpeza utilizado soluções ácidas ou dióxido de carbono gasoso são discutidos. Os métodos de limpeza incluem a adição de ácido à água afluente, de forma contínua ou periódica durante a penetração, escoando o módulo com uma solução ácida enquanto não há penetração e armazenando uma solução de dióxido de carbono gasoso no módulo, por um certo período de tempo, enquanto não há penetração, seguido por descarga. O sistema de filtração é igualmente divulgado."MULTIPLE MEMBRANE FILTERING MODULE". The filter module of multiple hollow fiber membranes of reverse osmosis or nano-filtration is suspended between a pair of opposite heads. The recesses of the membranes are on the side of the retainer or on the side of the tributary. The membranes are arranged in groups, such a sector of a cylinder, and form anterior and posterior stages. The permeate collection space is in direct hydraulic communication with each stage. The stages are connected by means of covers, with dividers located at the ends of the module. The module is used to filter the water, optionally with hollow fiber membranes adapted to reject the hardness caused by the salts and is therefore used to remove the hardness. Cleaning methods used acidic solutions or carbon dioxide gas are discussed. Cleaning methods include adding acid to the affluent water, continuously or periodically during penetration, draining the module with an acid solution while there is no penetration and storing a solution of gaseous carbon dioxide in the module for a certain period of time. time while there is no penetration, followed by discharge. The filtration system is also disclosed.
