Agriculture in Tunisia faces acute problems of water quality and quantity caused by limited conventional resources. One possibility to cope with low resources is purify wastewater for reuse. Among different methods the disinfection wastewater, inactivation fecal coliforms using a combination photosensitiser (Rose Bengal, Methylene Blue, cationic porphyrin) sunlight was determined on small scale. In parallel sensitizer photobleaching also followed under same conditions. The results described...
Intermittent infiltration–percolation is an extensively used treatment process which capable of oxidizing and decontaminating wastewater. The main purpose this study was to evaluate the efficiency regarding particularly removal phosphorus from urban wastewater effluents. mechanisms that may occur in sand filters were investigated. Results confirmed performed as advanced technique for suspended solids, organic matter nitrogen. However, it less efficient concerning reduction orthophosphate....
Groundwater resources play a very important role in satisfying people's everyday needs terms of consumption, irrigation and tourism. In Tunisia, as most countries the Mediterranean, groundwaters are fragile, under an arid or semi-arid climate, vulnerable to pollution, influenced by climate change. The Sminja aquifer northeast Tunisia is one major sources fresh water for city Zaghouan. Twenty-three wells boreholes were sampled January 2013 subjected salinity analysis elements nitrates. To...
The present study aims to assess the spatial and temporal variations of hydrochemical characteristics Mateur aquifer groundwaters, a crucial water resource in northeast Tunisia. was subject quality deterioration due salinization nitrate contamination, new assessment needed. For this purpose, 40 groundwater samples were collected during wet dry seasons analyzed for salinity, pH, T, O 2 , major cations anions, nutrient elements using standard methods Water Quality Index (WQI). results showed...
The total concentration and the speciation of heavy metals (Pb, Cd, Cu, Zn, Ni, Cr) in surface sediments Rades-Hamam Lif coast were determined, with particular focus on effect that urban industrial waste Meliane river has estuary coastal coast, off Mediterranean Sea. Several geochemical indices applied to assess risk contamination environmental risks sediments. concentrations these are influenced by runoff, industrial, wastewater. Pb, Ni affected anthropogenic sources, especially at mouth...
AbstractAbstractGroundwater is the most precious and valuable natural source of water in southeast Tunisia. The aim this study to find an adequate combination methods for a qualitative description geochemical processes into Zeuss-Koutine, Triassic Miocene groundwater system, unique region Mediterranean (Medenine, Jerba, Zarzis Jorf cities).Conventional classification techniques, statistical analyses kriging were used identify mineral distribution.This finds that chemistry mainly dominated by...
The production of phosphoric acid by the Tunisian Chemical Group, in Sfax, Tunisia, led to degradation groundwater quality Sfax-Agareb aquifer mainly phosphogypsum leachates infiltration. Spatiotemporal monitoring was carried out performing bimonthly sampling between October 2013 and 2014. Samples culled current study were subject physicochemical parameters measurements analysis major elements, orthophosphates, fluorine, trace metals, stable isotopes ( 18 O, 2 H). obtained results show that...
Boron is essential for crop growth but needed in very small amounts. The range between boron deficiency and toxicity plants quite narrow. These stress conditions gravely reduce yield quality of many species. Therefore, understanding the factors reactions affecting availability soil necessary. Against this framework, our research aims to determine available status a semiarid Dour Ismail irrigated perimeter (North Tunisia). objectives are also investigate distribution different particle-size...
Water erosion in Tunisian semi-arid regions causes harmful effects by silting reservoirs and reducing agricultural lands soil fertility. Several factors are involved the process: rain erosivity, fragility, degraded land cover on steep slopes associated with intensification of inappropriate human practices. Thus, identifying vulnerable sub-watersheds based assessed loss rate is very important to apply suitable conservation measures. The current research aimed prioritize risky areas Lakhmess...
