The master's thesis is based on the executed measurements of suspended solid contents,
COD contents and flows on the tested depth-cloth filtration device Mini filter 1 on WWTP
Domžale-Kamnik. The measurements were carried out in the period from 03.07.2012 –
20.9.2012 once a day from Monday till Friday on the tested filtration device and namely flow
measurements and reading of heights in the filtration device chambers and reading of
suspended solid contents (TSS) on the continuous measurement on the outflow from the
secondary clarifier. Measuring of parameters TSS and COD was carried out in the
laboratory.
After 17th of August 2012, the testing of tested filtration device was upgraded by including the
simulation of increased load with TSS on the inflow into the device. From that day on, the
load with TSS on the inflow into the tested device Mini filter 1 was gradually increased. The
purpose of simulation was to reach the load point with TSS where the cloth filtration device
Mini filter 1 will be constantly in the procedure of cleaning or removing the captured solid
particles from the filtration cloth. This point wasn't reached. Yet a minimum time during
rinsing under 2 minutes was achieved. Meaning, that the device was once again in the state
of cleaning less than 2 minutes. The cleaning procedure didn't affect the filtration process of
inflow water.
