Comparative study of improved treatment of oil produced-water using pure and chemically-impregnated activated carbon of banana peels and Luffa cylindrica

Produced water (PW) during oil and gas production operations contains various hazardous substances including heavy metals (HM) with adverse impact on the environment. Disposal of PW interferes with environmental sustainability, making PW treatment obligatory prior to discharge into the environment. Among previously available treatments of PW, environmentally sustainable methods using low-pore space bio-adsorbents...

Biological removal of iron from groundwater in a pilot column on a filter support material with coated jujube seeds

A co-flow pilot filter with a packing support material (coated jujube seeds) was constructed and tested for the biological removal of iron from Senegalese groundwater. Indeed, it is a PVC tube with an internal diameter of 40 mm and a height of 90 cm. The performance of the filter was tested at a constant hydraulic head of 261.67 m3/m2 per day while the iron feed concentrations varied between 0.5-1, 0.5-1.5 and 0.5-2...
