Coffee Wastewater - Water Usage

Water Usage

The amount of water used in processing depends strongly on the type of processing. Wet fully washed processing of the coffee cherries requires the most fresh water, dry processing the least. Sources indicate a wide range in water use. Recycling of water in the de-pulping process can drastically reduce the amount needed. With reuse and improved washing techniques, up to 1 to 6 m³ water per tonne of fresh coffee cherry is achievable; without reuse a consumption of up to 20m³/tonne is possible.

Famous quotes containing the words water and/or usage:

    The favor of a drop of water should be repaid as an overflowing spring.
    Chinese proverb.

    I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.
    —A.J. (Alfred Jules)
