Pit lakes in the Lausitz lignite mining district of Germany are diverse in size and morphometry. Many are extremely acidic with pH ≤ 3 and high in iron concentrations. Productivity in most of the mining lakes is generally low and they support only simple food webs; a few of the acidic lakes, with high nutrient concentrations, are highly productive. State planners hope to develop the lake region...
globally, increasing nitrate concentrations have become a significant environmental problem and a potential risk to public health. the world health organization (who) has set a limit of (10 (mg.l -1 )) no 3 - for human consumption and (100 mg.l -1 )) no 3 - for animals. water above these limits requires denitrification. nitrates causes cancer, blue-bay syndrome, hypertension and thyroid hypertr...
Background : The contamination of nitrate (NO3−) in potable water has become a serious concern in many parts of the world. Increasing nitrate concentrations in drinking water causes two adverse health effects: induction of “blue-baby syndrome” (methemoglobinemia), especially in infants, and the potential formation of carcinogenic nitrosamines. The objective of this study was to investigate th...
Adsorption Characteristics of Different Adsorbents and Iron(III) Salt for Removing As(V) from Water.
The aim of this study is to determine the adsorption performance of three types of adsorbents for removal of As(V) from water: Bayoxide® E33 (granular iron(III) oxide), Titansorb® (granular titanium oxide) and a suspension of precipitated iron(III) hydroxide. Results of As(V) adsorption stoichiometry of two commercial adsorbents and precipitated iron(III) hydroxide in tap and demineralized wate...
Abstract Background: Iron overload is a clinical consequence of repeated blood transfusions and causes significant organ damage, morbidity, and mortality in the absence of proper treatment. The primary targets of Iron chelators used for treating transfusional Iron overload are the prevention of Iron ingress into tissues and its intracellular scavenging. The present study was aimed at elucid...
Although the removal of colloidal particles continues to be an important reason for using coagulation, a newer objective, the removal of natural organic matter (NOM) to reduce the formation of disinfection by-products (DBPs), is growing in importance. Enhanced coagulation is thus introduced to most water utilities treating surface water. Bench-scale experiments were conducted to compare the eff...
