Ion exchange assessment for water treatment in brewing craft beer

Abstract

In order to diversify tourist offers and increase foreign currency income, Cuba
has assumed the execution of craft beer breweries, contracting the services and
technologies to foreign companies, but the contracts do not always include the
water treatment plant, being water one of the most important elements in the
manufacture of beer. Therefore, the objective of the research is: Assess an
available ion exchange system for water treatment in the manufacture of craft
beer. In the methodology used, the main water quality parameters of the brewery
water for the production of craft beers were identified and different types of resins
were experimentally studied to bring the water to the required parameters. As
conclusions it was obtained that: The characterization of the brewery water
allowed to determine, that this does not comply with the hardness ranges of 116-
207 mg/L (CaCO3) established for clear beers, the appropriate resin for water
treatment is Amberlite, which has an adsorption capacity of 38 458.2 mg/L of
resin, The industrial scaling of the existing ion exchange column allowed
determining the water treatment capacity per cycle, which was 62 788 L, as well
as the consumption of water and hydrochloric acid in the regeneration and
rinsing cycle of 7 401.14 L and 304.1 L,
