Abstract

Pivo sadrži 85-95% vode, što čini vodu jednom od najvažnijih sirovina u proizvodnji piva. Sastav vode utječe na kvalitetu piva, a sadržaj mineralnih tvari određuje vrstu piva. Tehnološka voda koja se koristi za proizvodnju piva mora u fizikalnom, kemijskom i mikrobiološkom smislu odgovarati kvaliteti vode za piće. U prirodnim vodama postoji određena koncentracija otopljenih tvari. Ako voda koja se koristi u proizvodnji piva ne odgovora standardima vode za piće, potrebno je provesti početne obrade vode kako bi se voda dezinficirala, najčešće kloriranjem, te filtraciju na pješčanim filterima, aeraciju i adsorpciju na aktivnom ugljenu kako bi se uklonile povišene koncentracije nepoželjnih tvari. Daljnjom obradom vode, koja uključuje ionsku izmjenu i membranske postupke, može se dobiti voda optimalnih vrijednosti za proizvodnju piva određenih karakteristika.

Abstract (english)

Beer contains 85-95% of water, which makes water very important raw material in beer production. Composition of water effects quality of the beer. Water for beer production due to physical, chemical and microbiological characteristics must comply with water for human consumption. There is a certain amount of dissolved matter present in natural water. If water for beer production does not match standards for drinking water, it is necessary to make preliminary water treatments to disinfect water, usually with chlorine dioxide, and to treat it by filtration, adsorption on activated carbon, aeration for the removal of certain components. Secondary water treatments, such as ion exchange and membrane technology, are used to obtain water for production of wanted quality and type of beer.
