20.500.12556/DKUM-66523 Compost leachate treatment using polyaluminium chloride and nanofiltration Laboratory scale filtration tests utilizing leachate were conducted to investigate fouling and filtration performance of nanofiltration membranes. The work presented in this study is conducted on real samples rather than model water. Physico-chemical analyses showed that the leachate contained a lot of organic substances, exceeding 20000 mg/L O2 expressed as chemical oxygen demand. Proper pre-treatment method must be chosen in order to reduce fouling index. Coagulation pre-treatment using poly-aluminium chloride was chosen. Two thin film polysulfone membranes were used, purchased by Osmonic Desal. The focus of this research is to assess the influence of the particle size and zeta-potential of the colloidal fraction in leachate on nanofiltration performance. The isoelectric point of both membranes was 4.7 and 4.3, respectively. The fouled membranes were negatively charged over the pH range with isoelectric point shifting to the left (lower pH) indicating the foulant material mainly not charged. It was confirmed by its zeta-potential, measured at -2 mV. compost leachate coagulation nanofiltration zeta potential kompost koagulacija nanofiltracija zeta potencial true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-06-29 13:40:25 2017-06-29 13:41:56 2022-07-11 03:07:29 2019-07-11 15:50:19 2017 0 0 str. 123-128 Letn. 15 Jun. 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 Y507-8113 66 28249383 20597270 10.1515/chem-2017-0015 Y507-8113 URN:SI:UM:DK:TSTFSXK9 Open_Chemistry_2017_Simonic_Compost_leachate_treatment_using_polyaluminium_chloride_and_nanofiltration.pdf Open_Chemistry_2017_Simonic_Compost_leachate_treatment_using_polyaluminium_chloride_and_nanofiltration.pdf 1 AD125D2D73BF3E3B8BEAB6F9B3EB3B6A 1a702ea6ff8e5d43adebaa1c5672493444cac2fee09c3130f650815e02697cc4 52eeba02-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113356 https://www.degruyter.com/view/j/chem.2017.15.issue-1/chem-2017-0015/chem-2017-0015.xml 1 https://dk.um.si/Dokument.php?lang=slv&id=113355 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
