| Abstract | Za napajanje olimpijskog bazena vodom, najčešće se koristi vodovodna mreža te se
nakon uvođenja u kompenzacijski bazen voda obrađuje i dovodi u bazen podnim mlaznicama.
Međutim, otvorenost bazena prema okolini i kupačima značajno utječe na kvalitetu vode koja
se s vremenom pogoršava. Kvaliteta vode u bazenu mora pri najvećem opterećenju udovoljavati
postavljenim zahtjevima, stoga se mora kontinuirano pročišćavati i održavati higijenski
prikladnom za piće, budući da se prilikom kupanja može nehotice unijeti u organizam.
Olimpijski bazen je bazen za plivanje i natjecanje te kao takav mora zadovoljavati zahtjeve
FINA-e (Fédération Internationale de Natation) [4], međunarodnog upravnog tijela za vodene
sportove kao što su plivanje, ronjenje, vaterpolo, sinkronizirano plivanje i plivanje u otvorenim
vodama. Zahtjev FINA-e je da temperatura vode mora biti između 25 i 28 °C, za vrijeme
natjecanja stabilna i bez značajnijih strujanja. Kako bi se osigurala željena temperatura vode te
omogućio rad bazena na otvorenome, potrebno je predvidjeti i proračunati grijanje vode, koje
će se osigurati kroz uporabu pločastog izmjenjivača topline. Prema normama DIN 19643-1 [1]
i DIN 19643-2 [2] te Pravilniku o sanitarno-tehničkim i higijenskim uvjetima bazenskih
kupališta [3], voda u bazenu mora biti obrađena na odgovarajući način kako bi se zadovoljili
zahtjevi za kvalitetom. U ovom diplomskom radu opisano je i proračunato postrojenje za obradu
vode vanjskog olimpijskog bazena koje se sastoji od filtracije sa staklenom ispunom, UV
dezinfekcije, grijanja vode pločastim izmjenjivačem te primjene određenih kemijskih sredstava
za obradu vode. |
| Abstract (english) | To supply an Olympic-sized swimming pool with water, the most common source is the
municipal water supply, which is then treated and introduced into the compensating tank before
being distributed through floor nozzles into the pool. However, the openness of the pool to the
surrounding environment and swimmers significantly affects the quality of the water, which
deteriorates over time. The water quality in the pool must meet the set requirements, particularly
during periods of high usage, so it must be continuously purified and kept hygienically safe for
drinking, as it can inadvertently enter the body during swimming. As an Olympic-sized pool is
designed for swimming and competition, it must meet the requirements of FINA (Fédération
Internationale de Natation) [4], the international governing body for aquatic sports such as
swimming, diving, water polo, synchronized swimming, and open water swimming. FINA
requires that the water temperature be between 25 and 28 °C, stable during competition, and
without significant currents. To ensure the desired water temperature and enable operation of
an outdoor pool, it is necessary to predict and calculate water heating, which will be provided
using a plate heat exchanger. According to DIN standards 19643-1 [1] and 19643-2 [2] and the
Regulation on Sanitary-Technical and Hygienic Conditions for Swimming Pools [3], the pool
water must be treated in an appropriate way to meet quality requirements. This thesis describes
and calculates a water treatment system for an outdoor Olympic-sized pool, consisting of
filtration with glass media, UV disinfection, water heating with a plate heat exchanger, and the
use of specific chemical agents for water treatment. |
