Among low cost and widely available raw materials, wastepaper sludge ash is of key interest as potential construction material. These materials come from the paper recycling industry. In present study, (WSA) retrieved UPM Chapelle Darblay Company located in south Rouen, France, were subjected to preliminary physicochemical characterization by X-ray fluorescence, laser granulometry scanning elec...

Abstract Iran's most important iron ore mine is located in the central region, and because of water shortage this area, need to reuse effluent from essential. On other hand, there are no suitable conditions for treating large volumes Iran. For reason, produced should be reduced returned consumption cycle by using appropriate technology. This study aimed investigate ozonation/lime effect on poly...

Abstract The sludge generated by wet scrubbing the off-gas from a silicomanganese plant in Norway represents significant loss silicon and manganese values. This work seeks to extract these values production of ferroalloys slags that can be utilized alternative industries. Carbothermic smelting together with iron or scraps at 1600 °C produced FeSiMn alloys consisting 57–64 wt.% Mn, 16–22 Si 18–2...

The dairy industry is one of the largest global producers wastewater and generates huge volumes processing sludge (DPS). There are two main types DPS, lime-treated dissolved air floatation bio-chemically-treated activated sludge. These may also be converted to STRUBIAS (STRUvite, BIochar, AShes) products which have potential as fertilizers, secondary feedstocks for phosphate fertiliser granules...

Abstract The metal-production industry creates a wide exhibit of strong waste, fluid effluents, and vaporous squanders. stable wastes include slag, powdery materials, sludge, scrap. So feasibility have look at metal slag recycling in fly ash bricks applied laboratory assessments commercial trials on three exceptional styles clay bodies. Crucial necessities consist grinding 90micron size, additi...
