Manganese waste water treatment by fungi derived from manganese slag
The aim of this study was to isolate a mould from the surface of manganese slag which had strong resistance and high adsorption of Mn2 + , and to determine the effects of initial Mn2 + concentration, incubation temperature, rotation speed and inoculation amount on adsorption of Mn2 + from manganese waste water solution. The result showed that a mould (A5) which was isolated from manganese slag ...

Manganese in Surface Water Sources
Manganese is one of the most abundant metals on the earth’s surface and various forms of it can be found in air, in soil, and in water. It doesn’t occur naturally in a pure state; oxides, carbonates and silicates are the most important manganese-containing minerals. When Manganese forms compounds in the environment with oxygen, sulfur (S), and chlorine, the resultant compounds are ...

City of Aurora, Oregon - Case Study
In late 2009, Water Works Engineers contacted AdEdge to design and implement an arsenic, iron, and manganese removal system to serve the City of Aurora, Oregon. The existing water supply consisted of three wells feeding into a centralized distribution system with a maximum combined capacity of 500 gpm. The site had an arsenic level of 12 ppb, above the EPA's MCL of 10 ppb. The City of Aurora also ...

The application of potassium manganate in water treatment
This paper explores the feasibility of using potassium manganate (K2MnO4) in water treatment. Manganate (Mn(VI)), like ferrate (Fe(VI)), can act as both an oxidant and a coagulant/adsorbent arising from the formation of insoluble manganese dioxide (Mn(IV)) from the chemical reduction of MnO42−. In this paper the basic properties of K2MnO4 are described, including the standard electrode potential ...

Treament of Hydrogen Sulfide (H2s)
This gas is often found in groundwater that contains iron and manganese. It is easily identified by its "rotten egg" odor. In addition to causing serious taste and odor problems, sulfide also promotes the growth of sulfur bacteria. Hydrogen sulfide can cause corrosion problems with iron and concrete pipes and reservoirs. Sulfides are formed by the anaerobic reduction of sulfates and organic ...

Talkeetna Water System, Alaska - Case Study
In late 2009, VEI Consultants contacted AdEdge Water Technologies to design, implement and startup an arsenic, iron, and manganese treatment system for the Talkeetna Water System in Talkeetna, Alaska. The existing water supply consisted of a well rated for 250 gpm with an arsenic level of 20 parts per billion (ppb). Iron and manganese levels were 0.04 mg/L and 0.10 mg/L respectively. The water ...
