Abstract

Nečistoće koje su u fontanskoj vodi dovedene od strane čovjeka ili okoliša, u kratkom vremenu mogu dostići razinu koja je opasna za ljude i za sigurnost opreme u sustavu tretiranja i filtriranja vode te se zbog toga voda za fontane mora adekvatno obraditi. Usprkos zabranama, dodir ljudi sa fontanskom vodom uvjetovao je određenu kvalitetu vode koja se mora zadovoljiti. Punjenje ili nadopuna vode u fontanskom sustavu vrši se iz vodovoda ili nekih drugih izvora vode, te se toj vodi prije ulaska u sustav obrade mora smanjiti tvrdoća. Zahtjevi za radom fontane u zimskom razdoblju uvjetuju grijanje vode te je potrebno predvidjeti grijač kroz koji mora prolaziti čista voda. Zbog svih nabrojanih razloga, i mnogih drugih, nužan je sustav pripreme vode kroz koji voda cirkulira. U ovome završnome radu objasnit će se i proračunati postrojenje za pripremu vode za fontane koji se temelji na umekšavanju, filtraciji, UV dezinfekciji, grijanju te dodavanju određenih kemijskih sredstava za tretiranje vode.

Abstract (english)

The impurities brought into the fountain water by person or the environment can, in short time, reach a level that is dangerous for people and for the safety of equipment in the system of treatment and filtration of water in the fountain, and therefore the water for fountains must be brought to a certain state of purity. Despite the prohibitions, the contact of people with the fountain water has conditioned a certain quality of water that must be met. Filling or replenishment of water in the fountain system is done from the water supply system or some other source, and therefore reduction of the hardness of water before entering the treatment system is required. The operation of the fountain in winter requires water heating, and it is necessary to provide a heater through which clean water must pass. For all these reasons, and many others, we need a system of water preparation through which water circulates. In this final paper, water treatment plants for fountains based on softening, filtration, UV disinfection, heating, addition of certain water treatment chemicals will be explained and calculated.
