Background and purpose: Access to safe drinking water is of the utmost importance in public health around the world. Presence of contaminants, such as secondary bacterial growth and endotoxins could reduce the quality of water resources. This study aimed at investigating the occurrence, seasonal variation, and removal of endotoxins in a conventional water treatment plant (WTP) in Tehran, Iran. ...

Background and Objective: The presence of natural organic materials (NOM) in water resources affects its quality (i.e. color, odor, and taste). In addition, it leads to the fouling of filters and membranes and reduces water treatment efficiency during flocculation/ coagulation. Moreover, NOM reacts with disinfectants and produces byproducts (DBPs), which are harmful to human health. Magnetic na...

This research project is designed to study the feasibility of removing or remediating nitrate/atrazine in groundwater using iron powder treatment. Iron powder was selected because it is cheap and nontoxic. Three different types of iron powders were used in this research. They were lab grade iron powder (about 0.02 micron in size), industrial grade iron powder (about 0.5 micron in size), and rus...

The paper presents the results of laboratory studies on removal phosphate in a wastewater treatment plant by adding sludge formed at water (water sludge—WTS) city Astana (Kazakhstan). Raw WTS from drying beds was used study, and content chemical compounds present dry residue determined, yielding 10.8–14.6% aluminum oxide (Al2O3) 4.58–5.31% iron (Fe2O3). moisture ranged 90.5 to 95.6%, ash 51.3 6...

Introduction: Color is one of the indices of water pollution. Discharge of colored effluent can damage to receiving water resources. One of the proposed methods for treating dyeing wastewater is electrocoagulation process. In this study, decolorization of the real textile effluent by electrocoagulation process using monopolar iron electrodes was studied. Methods: This study was run experiment...

A new media, iron coated pottery granules (ICPG) has been developed for As removal from drinking water. ICPG is a solid phase media that produces a stable Fe-Si surface complex for arsenic adsorption. Scanning electron microscopy (SEM) was used to document the physical attributes (grain size, pore size and distribution, surface roughness) of the ICPG media. Several advantages of the ICPG media ...

In this study trichloroethylene (TCE) removal from model solutions and groundwater by ferrate treatment was investigated applying different initial TCE concentrations, ferrate dosages and pH values. TCE concentrations were measured both in the vapor and liquid phases of water samples with head space gas chromatograph mass spectrometer (HS/GC-MS) and solid phase micro-extraction gas chromatograp...

Various countries in America have reported the existence of people suffering chronic exposure to levels of arsenic in drinking water that are higher than those envisaged in international standards. This is the case in Canada, the United States, Chile, Peru, Bolivia, Mexico, El Salvador and Nicaragua. Some of these countries have solved, either fully or in part, the problem of technology availab...
