The subject of research was groundwater from Quaternary formations with high concentration of total iron, increased colour and turbidity, and an increased amount of organic substances and manganese. Successful purification of such water creates technological problems and is practically impossible to achieve by applying traditional groundwater treatment processes. One of the ways recommended for...

The adsorption of Fe2+ by the manganese oxide coated zeolite (MOCZ) and iron oxide coated zeolite (FOCZ) was studied. Surface properties of adsorbents have been investigated for monitoring their changes and morphology for both of the MOCZ and FOCZ. Main variables namely; contact time, pH, initial concentration of Fe2+, size and dosage of adsorbent have been optimized, and the results contrasted...

Melanoidin is a compound produced by food industries and distilleries, which has negative impacts on the water environment due to high content of dissolved organic carbon dark color. Consequently, this work aims study catalytic properties multilayer graphene (MLG), molybdenum oxide (MoO2), manganese ferrite (MnFe2O4) in ozonation process remove melanoidin from solution. The results show that re...

colloids are small suspended particles in water which can not be settled or removed naturally due to their light weight and stability. these particles pose some degree of stability and cause water turbidity. there are some concerns regarding colloid removal efficiency in water treatment plants of iran. in this study, the effectiveness of aluminium sulfate and poly-aluminum chloride was evaluate...

GOAL, SCOPE AND BACKGROUND This paper is a part of the research work on 'Integrated treatment of industrial wastes towards prevention of regional water resources contamination - INTREAT' the project. It addresses the environmental pollution problems associated with solid and liquid waste/effluents produced by sulfide ore mining and metallurgical activities in the Copper Mining and Smelting Comp...

In Iraq. the municipalities are responsible for the production and delivery of drinking water (DW) .The quality of DW in Iraq is greatly deteriorated because of the war operation in this country Objective to study the effects of manganese chloride on histological testes, epididymis and kidney of rats and explore the dose –effects and time effects .The rats are randomly divided into six treatmen...

OBJECTIVE To rank pollutants in two Nigerian water supply schemes according to their effect on human health using a risk-based approach. METHODS Hazardous pollutants in drinking-water in the study area were identified from a literature search and selected pollutants were monitored from April 2010 to December 2011 in catchments, treatment works and consumer taps. The disease burden due to each...

up to now, lots of materials such as active carbon, iron, manganese, zirconium, and metal oxides have been widely used for removal of dyes from contaminated water. among these, ferrite nanoparticle is an interesting magnetic material due to its moderate saturation magnetization, excellent chemical stability and mechanical hardness. graphene, a new class of 2d carbonaceous material with atom thi...
