River Bank Filtration

Abstract Water purification of pollutants is a major challenge to the sustainable development of health in arid and arid regions of the world. Organization of water purification by the river bank filtration is a natural technique. Therefore, this survey was conducted to evaluate the shoulder of the Kufa River in purifying water from pollutants in an inexpensive and natural way. Six water samples were taken from six different locations of the river course, and six corresponding water samples were taken from the well locations near the river. The chemical analyzes of the samples were conducted during the month of December of the year 2020. The statistical analysis was carried out using the SAS program. The results showed that there were significant differences, as they showed the superiority of the concentration of phosphorous, cadmium, lead, copper, iron, manganese, chromium, molybdenum, and the total number of bacteria in river water compared to their concentration in well water. While it was observed that the concentration of total dissolved salts, sulfate, nickel and chlorine was superior in well water compared to river water. From this, it is clear that the effectiveness of the river shoulder technology in purifying the water of the Kufa River is low because the process of pumping water from wells is not continuous. It is assumed that to achieve the effectiveness of this technology, we need continuous months of pumping until the work of the river shoulder technology is achieved.

Riverbank filtration (RBF) provides an alternative to extract raw water by removing pollutants such as suspended solids, organic carbon, and pathogenic bacteria/microbes in the water. However, the main issue with this system is the occurrence of high concentrations of arsenic (As), iron (Fe), and manganese (Mn) in the production well. Therefore, this study was conducted to compare the presence of heavy metals in river water and pumping well water for an RBF system. Water samples were collected from Sungai Kerian (Kerian River) and a pumping well during a three-day pumping test. The heavy metal concentration in both samples was analyzed for 21 elements using ICP-OES. A total of 12 elements were detected in the water samples from either the river or the pumping well. Among the detected elements, As and Fe had concentrations that exceeded the standard values set by the Ministry of Health, Malaysia. Results also suggested that the Fe concentration in the pumping well water was higher than that in the river water. Conversely, As was more frequently detected in the river water than in the pumping well water. These results imply that the As concentration in the river water was derived from external sources, while the presence of As and Fe in the pumping well water was influenced by geochemical and hydrochemical processes in the aquifer.

River Bank Filtration

This paper summarizes results from a half-year sampling campaign in Budapest, when Danube River water and bank filtrate were analyzed for 36 emerging micropollutants. Twelve micropollutants were detected regularly in both river water and bank filtrate. Bisphenol A, carbamazepine, and sulfamethoxazole showed low removal (<20%) during bank filtration on Szentendre Island and Csepel island, whereas 1H-benzotriazole, tolyltriazole, diclofenac, cefepime, iomeprol, metazachlor, and acesulfame showed medium to high removal rates of up to 78%. The concentration range in bank filtrate was much lower compared to river water, proving the equilibration effect of bank filtration for water quality.

The main objective of this study is to confirm the potentials of Moringa oleifera seeds over alum for water purification. Various doses of Moringa seed powder 4, 8, 12 g/l were taken and checked for treatment of river and sewage water. After treatment of seed powder with water samples were analyzed for physico-chemical parameters like pH, Absorbance, TDS, TSS, Hardness, Chlorides, Conductivity, Turbidity, MPN and DO. Almost all parameters showed reduction with increasing dosage of Moringa seed powder. Similar doses of alum were checked with river water sample and were analyzed for above mentioned parameters. The results obtained showed that seed powder (natural coagulant) is more effective than conventional chemical coagulant., alum. The seed of Moringa oleifera is cheap, eco-friendly and non-toxic, can be effectively used as a coagulant for river and sewage water purification.

River Bank Filtration

Abstract River bank filtration systems are widely used for water supply purposes. Using these systems, the movement of water over short distances between the river bottom and extraction wells can decrease the concentrations of some contaminants. Such systems are especially important for the removal of specific micro-pollutants that seasonally appear in river water. In this article, pesticides migration at the Krajkowo well field is analysed based on different water extraction schemes. The water is extracted by two groups of wells (one located 60–80 m from the Warta River, and the second located more than 400 m from the river) and by a horizontal well with radial drains located 5 m below the river bottom. Based on this scheme, the rate of pesticide residues removal was analysed in wells located at different distances from the river channel. The results of the three sampling campaigns conducted in summer and autumn 2017 and winter 2018 indicate the presence of pesticide compounds in the Warta River (max. total concentration of 0.171 μg/l). The pesticides were also present in the horizontal well (max. total concentration of 0.137 μg/l). Much smaller concentrations (max. 0.064 μg/l) were observed in vertical wells located 60–80 m from the river. Additionally, in the well located 250 m from the river, only two pesticide constituents were detected (at concentrations just above the detection limit), and in a well located 680 m from the river, the concentrations of pesticide residues were below the detection limit (excluding isoproturon, which was slightly above the detection limit). This research illustrates the effectiveness of pesticides removal by river bank filtration.
