Abstract
U ovom radu je ispitan utjecaj NdFeB magneta na proces elektrokoagulacije u kombinaciji sa zeolitom u cilju pročišćavanja otpadne vode. Korišten je stakleni elektrokemijski reaktor s elektrodama od ugljičnog čelika pri čemu je NdFeB magnet bio smješten ispod reaktora. Ispitivanja su provedena u vremenskom periodu od 10 do 30 minuta, bez i s podešavanjem pH vrijednosti na pH = 3,72, pri čemu su mjereni parametri kao što su promjena pH vrijednosti i temperature otopine s vremenom, promjena mase elektroda, napon i sposobnost taloženja suspenzije. Rezultati su pokazali da postupak elektrokoagulacije s magnetom dovodi do nešto većeg porasta pH otopine i nešto manjeg porasta temperature u usporedbi s elektrokoagulacijskim postupkom. Primijećeno je smanjenje kemijske potrošnje kisika (KPK) za 84.08- 91.00% nakon 30 minuta provedbe eksperimenta, bez vidljivog utjecaja magneta na ove vrijednosti. Nešto veća oštećenja površine elektroda su vidljiva kod upotrebe magneta pri čemu se najveće promjene uočavaju kod mjerenja od 20 minuta. Smanjenje mase anode raste s vremenom provođenja eksperimenta, a uočena je i mala promjena mase katode. Oba hibridna postupka omogućuju 80-100% regeneracije mase zeolita. Manja potrošnja energije (niže vrijednosti napona i snage) su potrebne kod postupaka koji su provedeni korištenjem magneta u odnosu na eksperimente bez magneta. Pozitivan utjecaj magneta na taloženje zamijećen je u eksperimentu s vremenom kontakta od 20 minuta.
Abstract (english)
In this work, the influence of the NdFeB magnet on the electrocoagulation process in combination with zeolite for wastewater treatment is investigated. An electrochemical glass reactor with carbon steel electrodes was used, under which a NdFeB magnet was attached. The tests were carried out over a period of 10 to 30 minutes, without and with the pH adjusted to pH = 3.72, measuring parameters such as the change in pH and temperature of the solution over time, the change in the mass of the electrode, the voltage and the ability to settle the suspension. The results showed that the electrocoagulation method with a magnet led to a slightly higher increase in the pH of the solution and a slightly lower increase in temperature compared to the electrocoagulation method. After 30 minutes of the experiment, a decrease in chemical oxygen demand (COD) of 84.08-91.00% was observed without the magnet having a visible effect on these values. When a magnet is used, slightly greater damage to the electrode surface is visible, with the most significant changes observed in measurements from 20 minutes onwards. The decrease in the anode's mass increases with the experiment's duration, but a small change can also be observed in the mass of the cathode. Both hybrid processes enable 80-100% regeneration of the zeolite. Procedures carried out with a magnet require less energy consumption (lower voltage and power values) than experiments without a magnet. The positive influence of the magnet on the deposition was observed in the experiment with a contact time of 20 minutes.
