Water scrubbing

A case study for Elabered estate, a farm located 63km north-west of Asmara, Eritrea was conducted for a biogas plant implementation. Cow dung was taken to be the main feedstock for the biogas digester. The total quantity of manure estimated was 3000kg out of 300 cows per day. Having this, 173m3 /day biogas production was estimated. Assuming the produced biogas to be upgraded up to 95% CH4 content the total energy generation potential is equivalent to 1089.7kWh/day.

Beneficiation (or concentration) processes are gener- ally used to upgrade the phosphate content by removing contaminants and barren material prior to further processing. A few ores are of sufficiently high quality to require no further concentration. The natu- rally occurring impurities contained in phosphate rock ore depend heavily on the type of deposit (sedi- mentary or igneous), associated minerals, and the extent of weathering. Major impurities can include organic matter, clay and other fines, siliceous material, carbonates, and iron bearing minerals.
