Craft breweries can produce five to 10 litres of wastewater for every litre of beer that they package and sell. High in organic matter and suspended solids, the wastewater’s impact can be equivalent to adding another small town to a municipality’s water treatment burden. It’s also a challenge for brewers when they must pay water consumption surcharges and find ways to optimize their processes.
Check out this presentation by Shimadzu, which provides an expansive view on the utility of a UV-Vis spectrophotometer to a brewer. This multi-functional, relatively inexpensive system can measure various parameters: from colour and bitterness to diacetyl, dissolved oxygen and polyphenols. Watch it here.
