Evaluating Bank Filtration as an Alternative to the Current Water Supply from Deeper Aquifer: A Case Study from the Pannonian Basin, Serbia

Abstract

Groundwater from a depth of 100-200 m is the main source of public water supply in most municipalities in the Pannonian basin in central and southeastern Europe. Even though its quality does not always meet EU standards for drinking water-including those regarding arsenic-in many villages and even in some major cities no treatment except chlorination takes place. Of the several alternatives to improve the water supply situation in the Autonomous Province of Vojvodina in the northern part of the Republic of Serbia, re-orientation towards more centralized systems combined with river bank filtration as an additional and sustainable raw water resource was evaluated as the best. A hydrogeological and hydrochemical survey of the Tisa (or Tisza) River alluvium in the Padej test field confirmed the aptness of this approach. A good connection between the Tisa River bed and the alluvial aquifer consisting of fine-grained sand was found (average hydraulic conductivity of 5×10 −5 m/s). With appropriately designed and managed wells, 80-100 l/s bank filtrate per km of river bank can be produced for water supply. Comprehensive analysis of the river water and river bank filtrate as well as a pilot treatment of the bank filtrate suggest that aeration-oxidation-flocculation-filtration-disinfection is a suitable technology for the Tisa River bank filtrate.

Biodegradation Model of Dissolved Organic Matter during River Bank Filtration, at Al-Qurain City, Sharkyia Governorate, Egypt

“…The correlation coefficient between DOC recorded, and DOC estimated was very strong 0.94, as shown in The data shows that the reduction of turbidity with El Muzainin RBF and groundwater well was about 98 %. This is in accordance with [19,20], who cited that; the highest reduction percentage of turbidity in the RBF system, also the studies of [15,21,22] who showed that the highest performance and stability of RBF system in reducing.…”

“…Fe concentration in El Saadia canal ≤ 0.016 mg/l and Mn concentration ≤ 0.007 mg/l, El Muzainin RBF results of Fe varied from 0.007 to 0.02 mg/l and Mn varied from 0.001 to 0.009 mg/l, groundwater well results of Fe varied from 0.26 to 0.49 mg/l with average 0.39 mg/l and Mn varied from 0.06 to 0.14 mg/l. Many studies were conducted by [21,22,25] showed that the values of Fe and Mn concentrations in the RBF system are less than groundwater.…”

“…The application of the (BF) technique is well consolidated in the world scenario. A number of European countries such as Germany (Hoffmann & Gunkel, ), Holland (Stuyfzand, Juhàsz‐Holterman, & Lange, ), France (Kedziorek, Geoffriau, & Bourg, ), Hungary (Plutzer, Tako´, Márialigeti, Törökné, & Karanis, ), Czech Republic (Buzek, Kadlecova, Jackova, & Lnenickova, ), and Republic of Serbia (Stauder et al, ) have used this technique as an important source for the production of water for human consumption for several decades.…”

“…Tako se i određivanje i održavanje zona sanitarne zaštite izvorišta, koje se realizuje aktuel- nim Pravilnikom [2], vrši primenom "modelskih" (hidrodinamičkih) ispitivanja kretanja podzemnih voda u vodonosnoj sredini izvorišta. Za period od par godina unazad, problemima izvorišta u Srbiji, bilo da se radi o istraživanjima i hidrodinamičkom aspektu hidrogeoloških istraživanja [3,4,5], optimalnom korišćenju voda i održivom upravljanju [6,7,12], vodosnabdevanju [8], uticaju nekih faktora na izvorište i pratećim procesima tokom rada izvorišta [9,10], kvalitetu voda [11] ili zaštiti izvorišta [13,14], bavili su se mnogi autori. U ovom radu, primenom hidrodinamičke analize određen je međusobni uticaj dva izvorišta podzemnih voda kroz različite varijante povećanja eksploatacije podzemnih voda tokom perioda od 10 godina.…”
