Abstract

<B>TRATAMENTO DE áGUA PARA RETIRAR SóLIDOS DISSOLVIDOS<D>. Tratamento de água para retirar sólidos dissolvidos, o qual revela um dessalinizador para retirar sólidos dissolvidos da água do mar ou água salobra. O dessalinizador (10) compreendendo um invólucro (12) no qual uma bomba (14) acionada por um motor (16) bombeia água do mar ou água salobra sob pressão. Um cartucho de dessalinização (76) no invólucro (12) inclui material semi-permeável que atua como uma membrana de osmose inversa e através da qual o permeado é forçado a separar a mesma da água do mar ou água salobra. Os sólidos dissolvidos na água salobra ou água do mar são retidos nas passagens de retenção de sal do cartucho (76). Três bobinas elétricas 949, 96 e 98) circundam o cartucho (76) e são embutidas nas paredes do invólucro (12). As bobinas são abastecidas com corrente de um suprimento (112) que é preferivelmente um suprimento trifásico de 50 hertz, 380 volts. As bobinas são também conectadas por linhas (108) a um acionamento de CA de freq³ência ajustável (110) que é por sua vez conectado ao motor (16). As bobinas (94, 96 e 98) impõe um campo magnético sobre a água do mar ou água salobra nas passagens de retenção de sal que aumenta a taxa na qual a água permeia através da membrana de osmose inversa e também inibe incrustações. As bobinas (94, 96 e 98) atuam adicionalmente como estranguladores para o motor (16).
