Abstract

Koncentracije nitrata u podzemnim i površinskim vodama su u porastu, a uzrok te pojave je u velikoj mjeri zbog ljudskog djelovanja. Suvišna gnojidba tla, nekontrolirano ispuštanje otpadnih voda i kemikalija jedni su od glavnih izvora zagađenja voda nitratima. Visoki sadržaj nitrata u pitkoj vodi može uzrokovati razne probleme za ljudsko zdravlje i zbog toga će biti sve veća potreba za njihovim uklanjanjem iz voda za piće. U ovom radu će se objasniti i proračunati postrojenje za uklanjanje nitrata u bunarskoj vodi koje se temelji na tehnologiji ionske izmjene jer se ona smatra jednom od najučinkovitih postupaka.

Abstract (english)

Nitrate concentrations in groundwater and surface water are constantly being increased, and the cause is largely due to human activity. Excessive soil fertilization, uncontrolled discharge of wastewater and chemicals are one of the main sources of nitrate pollution in water. The high content of nitrate in drinking water can cause various problems for human health and therefore the need for eliminating them in drinking water will increase. In this thesis it will be explained and calculated the plant for nitrate removal in drinking water based on ion exchange technology because it is considered to be one of the most effective processes.
