Preservation of reverse osmosis membranes with non oxidizing biocides – comparison with SMBSSodium metabisulphite (SMBS) is the current standard preservation chemical used in RO plants during shut down. It is a cheap and efficient preservative, but its tendency to oxidize easily has several drawbacks. The use of a non-oxidizing biocide instead could solve some of the issues currently seen with the SMBS, but little has been reported about membrane compatibility and preservation ef... ... hiện toàn bộ

Oxidized fulvic acid adsorption on activated carbonThis study evaluates and compares the parameters of equilibrium adsorption from aqueous solutions of river fulvic acids (FA) and peat fulvic acids. Compared to peat FA, the river FA had lower biodegradable dissolved organic carbon (BDOC). We observed a tendency for correlation between change of Gibbs free energy of adsorption and BDOC value. A chlorination dose of 1.4 mg L−1 did not change... ... hiện toàn bộ

Rethinking urban areas: an example of an integrated blue-green approachThe provision of high quality urban water services, the assets of which are often conceptualised as ‘blue infrastructure’, is essential for public health and quality of life in the cities. On the other hand, parks, recreation grounds, gardens, green roofs and in general ‘green infrastructure’, provide a range of (urban) ecosystem services (including quality of life and aesthetics) and coul... ... hiện toàn bộ

Geographic information system and multi-criteria decision analysis for the determination of groundwater recharge potential: systematic reviewAbstract
The groundwater recharge area is one of the crucial components in regional development. Many studies in determining groundwater recharge areas with a combination of Geographic Information System and Multi-criteria Decision Analysis have been carried out. The development of studies over the last ten years is reviewed in this paper using the P... ... hiện toàn bộ

Pharmaceutical removal during managed aquifer recharge with pretreatment by advanced oxidationOrganic micropollutants (OMPs) are detected in sources for drinking water and treatment possibilities are investigated. Innovative removal technologies are available such as membrane filtration and advanced oxidation, but also biological treatment should be considered. By combining an advanced oxidation process with managed aquifer recharge (MAR), two complementary processes are expected t... ... hiện toàn bộ

Antibiotics in groundwater under locations with high livestock density in GermanyAntibiotics are deployed in large quantities both in human and in veterinary medicine. Studies show that antibiotic residues occur in the environment (e.g. soil and surface waters). In some cases they were also detected in ground and drinking water. However, the degree of groundwater pollution by antibiotic residues from livestock farming is unknown. Therefore, the federal environment agen... ... hiện toàn bộ

The use of principal component analysis for the assessment of the spatial variability of curative waters from the Busko-Zdrój and Solec-Zdrój region (Poland) – preliminary resultsAbstract
In the Busko-Zdrój and Solec-Zdrój region (Poland), curative waters with different concentrations of sulphur(II) compounds are extracted. In this paper, waters from 14 intakes were considered. The waters analysed are chloride-sodium, sulphide, iodide (Cl–Na, S, I) or chloride-sodium, sulphide (Cl–Na, S) and are especially associated with dee... ... hiện toàn bộ

Biodegradation of the cyanobacterial hepatotoxin [Dha7] microcystin-LR within a biologically active sand filterCyanobacterial blooms in Thailand waters contain microcystin (MC) hepatotoxins that are a risk to animal and human health. The biodegradation of MCs is a safe and natural method of removal from water. The [Dha7] MC-LR was purified by chromatography, identified by liquid chromatography–tandem mass spectrometry (LC-MS) and used for examining the biodegradation of MCs. Analysis of MC levels r... ... hiện toàn bộ

Burst detection and location in water distribution networksAn algorithm for the detection and location of sudden bursts in water distribution networks combining both continuous monitoring of pressure and hydraulic transient computation is presented. The approach is designed for medium and large bursts that are the result of the sudden rupture of the pipe wall or other physical element in the network and are accompanied by the transient pressure wa... ... hiện toàn bộ

Impact of irrigation water scarcity on rural household food security and income in PakistanAs Pakistan is currently facing a severe shortage of irrigation water, this paper analyzes the determinants of water scarcity and its impact on the yield of cereal crops (wheat, maize and rice), household income, food security and poverty levels by employing the propensity-score-matching approach. This study is based on a comprehensive set of cross-sectional data collected from 950 farmers... ... hiện toàn bộ
