Water saving is becoming a key interest for many bottlers. This complex aspect not only depends on the efficiency of one subsystem such as a RO, but equally from a global approach of the water use and rejection in the plant. To improve the bottling ratio, water reuse is the main gateway to water savings. Collecting the water, determining the quality of the rejected water, separating the water according to it's reuse possibility, and the choice of which water treatment is adequate is a core expertise which ICE has been performing for the past 15 years. Local regulations are key parameters in the water savings equation.
