Reaproveitamento do concentrado gerado por sistema de tratamento de água por osmose reversa em uma clínica de hemodiálise

Abstract

by the clinic was observed. The achieved results meet the four classes of reuse, but it was observed that the fluoride parameter result was equal to the drinking water standard limit.

Métodos De Purificação Da Água Para Laboratórios

“…Tal método apresenta considerável geração de rejeitos, uma vez que há a retenção de compostos. Entretanto, considerando que a água que chega ao equipamento de osmose reversa no laboratório já passou por outros processos de purificação, estudos indicam que esta água pode ser reaproveitada, seja para a limpeza externa, seja com sua diluição para eventuais usos mais nobres (FARIA et al, 2016;RIBEIRO et al, 2016).…”

Technical feasibility of reuse of effluent generated from reverse osmosis system in a pharmaceutical plant

“…Silva and Teixeira (2011) and Faria et al (2016) studied the feasibility of the reuse of concentrate from reverse osmosis in hemodialysis units. These authors found large volumes of concentrate being generated by these systems and recommended their reuse in external cleaning and firefighting.…”

“…These authors found large volumes of concentrate being generated by these systems and recommended their reuse in external cleaning and firefighting. They regretted that despite the high quality of these effluents, the lack of a specific regulation for the water reuse prevents a better use of this waste (Faria et al, 2016). The studies of effluent reuse require an advanced pretreatment (Colla et al, 2015;Zheng et al, 2015), especially in the food industry (Casani et al, 2005;Götz et al, 2014;Suárez et al, 2014).…”

“…Some studies in hemodialysis clinics have suggested the use of this kind of effluent (concentrate generated from a reverse osmosis system) for washing external areas (Silva and Teixeira, 2011;Faria et al, 2016;Ribeiro et al, 2016). However, some authors recommended that this effluent could be better used like potable water (Faria et al, 2016).…”

However, some authors recommended that this effluent could be better used like potable water (Faria et al, 2016). Thus, the aims of this study were: (1) to prepare the balance of water for vaccine production; (2) to propose the reuse of effluent generated from the production of purified water; and (3) to estimate the savings for this pharmaceutical company were this proposal adopted.…”
