QUESTÃO 02 ENUNCIADO Segundo Bittencourt 2014 o processo de osmose inversa é ideal para remoção de matéria orgânica natural tratamento avançado para reuso de água potável remoção de contaminantes específicos dessalinização da água do mar e de águas subterrâneas salobras e para abrandamento Instalações de OI possuem sistemas de prétratamento bombas de alimentação vasos de pressão contendo elementos de membrana e sistemas de póstratamento O processo ocorre com a água de alimentação é pressurizada para o vaso de pressão entrando em contato com o primeiro elemento da membrana Para compreender a osmose inversa a pressão osmótica é essencial visto que requer uma força motriz para o fluxo na direção oposta Referência BITTENCOURT C PAULA M A S de Tratamento de água e efluentes

QUESTÃO 02 ENUNCIADO Segundo Bittencourt 2014 o processo de osmose inversa é ideal para remoção de matéria orgânica natural tratamento avançado para reuso de água potável remoção de contaminantes específicos dessalinização da água do mar e de águas subterrâneas salobras e para abrandamento Instalações de OI possuem sistemas de prétratamento bombas de alimentação vasos de pressão contendo elementos de membrana e sistemas de póstratamento O processo ocorre com a água de alimentação é pressurizada para o vaso de pressão entrando em contato com o primeiro elemento da membrana Para compreender a osmose inversa a pressão osmótica é essencial visto que requer uma força motriz para o fluxo na direção oposta Referência BITTENCOURT C PAULA M A S de Tratamento de água e efluentes
