Abstract

Proučavanje beskralježnjaka u vodoopskrbnim sustavima je važno je jer se time dobiva uvid u probleme koju izaziva njihova pojava u pitkoj vodi. Njihovo pojavljivanje i preživljavanje u takvome sustavu značajan je estetski i zdravstveni problem. Neki beskralježnjaci uspješno preživljavaju proces pročišćavanja podzemnih i površinskih voda. U stanju su kolonizirati pojedine dijelove tehnološkog procesa obrade pitkih voda, spremnike čiste vode i vodoopskrbne sustave. Na taj način često dolazi do pojave njihove prisutnosti u obrađenoj pitkoj vodi. Naime, dominantne svojite beskralježnjaka u vodoopskrbnim sustavima pitke vode su uglavnom kozmopolitske i eurivalentne vrste, biološki vektori koji su prijenosnici uzročnika različitih bolesti (virusa, bakterija, praživotinja i drugih beskralježnjaka). Poznato je da prisutnost i preživljavanje beskralježnjaka u vodoopskrbnim sustavima pitke vode je u pozitivnoj korelaciji s koncentracijom organskog detritusa i biofilmom u takvom sustavu. No, budući da takva temeljita istraživanja u vodoopskrbnim sustavima u Republici Hrvatskoj nisu još provedena, cilj rada je bio istraživanjem utvrditi prisutnosti beskralježnjaka u vodoopskrbnim sustavima pitke vode u Istočnoj Hrvatskoj, statističkim analizama utvrditi jesu li fizikalno-kemijske analize vode za ljudsku potrošnju u korelaciji s brojnošću beskralježnjaka. Nadalje, cilj je razraditi i učinkovite postupke njihova uklanjanja primjenom: klora, klorovog dioksida i ozona. Provedenim istraživanjima dokazano je da su različite taksonomske skupine beskralježnjaka kolonizirale istraživane vodoopskrbne sustave. Utvrđeno je da fizikalno-kemijski parametri značajno utječu na njihovo preživljavanje u vodoopskrbnom sustavu. Došlo se i do rezultata koje su koncentracije dezinfekcijskog sredstva potrebne za uspješnu inaktivaciju i uklanjanje iz vodoopskrbnih sustava.

Abstract (english)

The study of invertebrates in water supply systems is important because it provides insight into the problems caused by their occurrence in drinking water. Their origin and survival in such a system is a significant aesthetic and health problem. Some invertebrates successfully survive the process of groundwater and surface water treatment. They are able to colonize certain parts of the technological process of drinking water treatment, clean water tanks and water supply systems. In this way, their presence in treated drinking water often occurs. Specifically, the dominant species of invertebrates in drinking water distribution systems are mainly cosmopolitan and eurivalent species, biological vectors that are carriers of agents of different diseases (viruses, bacteria, protozoa and other invertebrates). It is known that the presence and survival of invertebrates in drinking water distribution systems are in positive correlation with the concentration of organic detritus and biofilm in such a system. However, such an extensive research in water supply systems in our country have not bin implemented yet, the goal of the proposed research has bin identifying the presence of invertebrates in drinking water distribution systems in eastern Croatia, using statistical analyzes to determine whether the physicochemical parameters of water for human consumption correlate with the abundance of invertebrates. Furthermore, the aim is to develop effective procedures for their removal using: chlorine, chlorine dioxide and ozone. Through research, it has been proven that different taxonomic groups of invertebrates colonized the investigated water supply systems. We also found that physicochemical parameters significantly affect their survival in the water supply system. It came to the results of what disinfectant concentrations are required for successful inactivation and removal from water supply systems.
