reverse osmosis

The water obtained by reverse osmosis was studied and the method of regulating the composition of its ions, necessary for the use of this water in the mashing process in order to obtain high-quality beer, was considered. The influence of mash water ions on beer quality indicators was studied. It was found that the concentrations of individual ions in water have the greatest effect on the organoleptic parameters of the finished drink and especially on the hop bitterness.

The problem of drinking water preparation with specified quantitative and qualitative composition is very acute today in various countries including Ukraine. The consequences of using the method of reverse osmosis at tap water purification using the equipment with the membrane element Filmtec XLE 440 (8"), produced by DOW Chemical (USA), have been reviewed. Positive characteristics as well as economical and technological shortcomings of reverse osmosis equipment have been proved.
