Abstract EN

This study was conducted in order to evaluate the uses of sulfur –rich water found in the Western desert of Iraq an assessment was made to select more suitable procedure for using this type of water without negative health and environmental effects, so a field survey of the wells in area was under taken, measuring its discharge sulfur content.

Multi-stage treatment system was made using different material such as fermented wheat straw with A.

niger, spent mushroom compost, and calcinated rock phosphate, limestone inoculated with sulfur oxidizing and reducing bacteria, also using continuous treatment system for different time interval of 12, 24, and 36 hour.

The results showed existence of sulfur-rich water in Km70 area was superior in its sulfur content 2000 mg l-1.

treatments W1 and W2 removed SO4 and hydrogen sulfide by 66.01 and 64.7, 90.97, and 91.6% respectively.

Time interval treatment 24 hour.

The values of potential salinity in the case of continuous treatments W1 and W2 for 24 hours approached the rates of 12.15 and 11.66, respectively.

The efficiency of continuous treatment unit W1 and W2 for hundred days period approached 72 and 96% , respectively.
