Development of conceptual models in water treatment systems

Ovim radom se ukazuje na postupke pročišćavanja otpadnih voda, te sa željom za očuvanjem vode potrebno je redovito provoditi kontrolu odnosno nadzor nad dolaznim i ispusnim vodama. Rad je koncipiran u nekoliko cjelina. U uvodnom djelu upućeni smo u opće informacije o vodi, načinu kruženja u prirodi te problemima koje donosi njihovo onečišćenje, dok su u drugom dijelu opisane otpadne vode, njihova fizikalna svojstva te glavna podjela. U trećem djelu objašnjene su glavne metode pročišćavanja otpadnih voda te daljnja podjela postupaka i uređaja. U četvrtom i petom djelu objašnjen je pogon za pročišćvanje podzemne vode u Ravniku, te su prikazani konceptualni modeli i njihove funkcije.This article refers to the processes of wastewater treatment, and with the desire to preserve the water it is necessary to regularly carry out control and supervision of the incoming and outgoing water. The work is divided into several sections. In the introductory part we addressed the general information on water circulation mode in nature and problems brought on their pollution, while the second part describes the waste water, their physical properties and main division. The third part explains the main methods of wastewater treatment and subdivision methods and devices. In the fourth and fifth part, an explanation of the groundwater treatment plant in Ravnik is presented, and conceptual models and their functions
