Reverse osmosis unit/appliance; RO unit
Pressão, nesse caso, refere-se à pressão da própria água, já que é essa pressão que força a mesma água a passar por uma membrana de purificação, sendo que através desse processo (de pressão) a água purificada é, então, separada dos sólidos/contaminantes que serão rejeitados.
