Abstract

"PROCESSO, SISTEMA E APARELHO PARA TRATAMENTO DE áGUA". São divulgados uma aparelhagem e um processo para tratamento de água em que é usado um ciclo de tratamento de desalcalinização em associação com um ciclo de ajuste de pH ou com um ciclo de regeneração ou com ambos. O ciclo de tratamento envolve o contato de água não tratado com resina de troca catiónica de ácido fraco, opcionalmente seguido por ajuste de pH. O ciclo de regeneração inclui o contato de resina de troca catiónica de ácido fraco parcialmente esgotada com regeneradores de ácido fraco, em particular ácido carbónico; o uso de regeneradores de ácido fraco evita a introdução de depósitos excessivos de sais inorgânicos no ambiente. O sistema de tratamento de água também pode ser disposto para permitir ciclos concorrentes de tratamento e de regeneração e é útil para fornecer água tratada sob demanda tanto para uso doméstico como para serviço de bebidas.
