Abstract
U ovom radu ispitano je djelovanje magneta na učinkovitost obrade otpadne kompostne vode s hibridinim procesom elektrokoagulacije s aluminijevim elektrodama uz dodatak sintetskog zeolita i primjene magneta. Eksperimenti su provedeni u trajanju od 10 do 30 minuta bez podešavanja početne pH vrijednosti, uz dvije brzine vrtnje miješala od 250 i 350 okr./min te prisutnost i odsutnost magneta. Učinkovitost procesa ispitivana je preko fizikalno-kemijskih pokazatelja, promjene mase elektroda te sposobnosti taloženja suspenzije. Na kraju je provedena analiza operativnih troškova na temelju Faradayeva zakona i stvarne potrošnje elektroda. Rezultati su pokazali da je nešto veći porast temperature otopine u eksperimentima s magnetom u trajanju od 20 i 30 minuta, porast pH vrijednosti za eksperimente u trajanju od 30 minuta, dok vrijednosti električne vodljivosti i prikupljene mase taloga osciliraju ovisno o vremenu kontakta, prisutnosti magneta i brzini vrtnje miješala. Prisutnost magneta je kod eksperimenata u trajanju od 30 minuta pridonijela većem smanjenju kemijske potrošnje kisika (KPK), a u eksperimentima u trajanju od 20 i 30 minuta za uklanjanje mutnoće. Međutim, elektrokoagulacija potpomognuta magnetom pokazuje trend veće potrošnje električne energije, dok je manja potrošnja elektroda uočena samo u eksperimentima pri 20 min vremena kontakta i brzini vrtnje od 250 okr./min.
Abstract (english)
In this paper, the effect of magnets on the efficiency of waste compost water treatment with the hybrid process of electrocoagulation with aluminum electrodes with the addition of synthetic zeolite and magnets usage was examined. The experiments were carried out for 10 to 30 minutes without adjusting the initial pH value, with two mixing speeds of 250 and 350 rpm and the presence or absence of a magnet. The effectiveness of the process was examined through physico-chemical indicators, changes in the mass of the electrodes and the ability to settle the suspension. At the end, an analysis of operating costs was evaluated based on Faraday's law and the actual consumption of electrodes. The results showed that the increase in the temperature of the solution in the experiments with a magnet lasting 20 and 30 minutes was slightly higher, the increase in the pH value for the experiments lasting 30 minutes, while the values of the electrical conductivity and the collected mass of the precipitate fluctuated depending on the contact time, the presence of the magnet and mixing speed. The presence of the magnet contributed to a greater reduction of COD in the 30-minute experiments, and to the removal of turbidity in the 20- and 30-minute experiments. However, magnet-assisted electrocoagulation shows a trend of higher electricity consumption, while lower electrode consumption was observed only in experiments with 20 min of contact time and a rotation speed of 250 rpm.
