Uklanjanje visokog sadržaja organskih i neorganskih polutana iz podzemnih voda Vojvodine primenom nanofiltracije / Organic and inorganic polutants high content removal from Vojvodina groundwater by application of nanofiltration

The goal of this thesis was to examine removal possibility of high concentrations of organic and inorganic matter from aquatic solution using “Crossflow” spiral wound nanofiltration membranes. Natural organic matter, ammonia ions and total arsenic removal was examined using concentrates – waste water obtained from industrial nanofiltration plant and they present NFCP experiment series. Removal of high concentrations of calcium, magnesium, iron and manganese ions was a part of NFWP experiments and was conducted using natural groundwater. Optimal fluxes and transmembrane pressures, as well as complexing substances dosage concentrations were determined. Obtained results in semi industrial scale are practically applicable on the large scale plants for drinking water preparation from deep wells, as well as from shallow aquifers. Application of presented results, concerning drinking water preparation from deep wells with significant savings of water resources, is designed especially for locations in Pannonia basin. Shallow aquifer well water treatment is applicable in practice especially because of addition of organic complexation agents that substitutes conventional deferization and manganese removal methods ultimately reducing investment and exploitation costs. On the basis of obtained results, industrial plant that produces drinking water from Zrenjanin aquifer deep well was designed. Furthermore, potable water industrial plant was designed that used shallow aquifer well water located in Bačka Palanka region, settlement Despotovo.
