Disposal of molasses wastewater of Alcohol production and sugar refinery plants into water resources make irreparable damages to the environment. Continuous disposal of this wastewater causes decreases soil quality and destroys agricultural products. Wastewater which is produced from molasses alcoholic fermentation causes numerous environmental issues due to the dark color and high level of organic compounds. Most of these organic compounds can be eliminated by aerobic or anaerobic biological treatments. Nevertheless, the color which is due to the presence of heavy organic compounds, named melanoidin, in wastewater is hardly removed by conventional biological treatments. In this project, the... 

Midrex sponge iron is an active product and there are several problems with store and export it.Cold briquetting sponge iron method is a new method to protect sponge iron from oxidation and provides the possibility of its storage and transportation. Iran as one of the biggest countries that produce sponge iron, has a lot of sponge iron pilots that equipped with cold briquetted machines,but their production capacity is limited and is about 5 percent of their production capacity. With regard to no need for country to these amount of sponge iron, most of these pilots have to store and transport large volumes of sponge iron and the risk of oxidation and fire threatens these units.By using cold... 

The treatment of water effluent from alcohol industries is among the most challenging industrial wastewater treatments. The challenge mainly arises from the high capacity of organic compounds allowing the growth of microorganisms and pollutants. Brown color of the wastewater also contributes to this phenomenon; it absorbs more sunlight which then reduces the oxygenation of water and thus adversely affecting the aquatic life. Moreover, the acidity of the wastewater decreases the pH level of agricultural soils, so its quality Thus, distillery wastewater, without any treatment can pose a serious threat to the environment. In our study, we investigate the decolorization of molasses wastewater...
