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

چکیده
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 PVC tube an internal diameter 40 mm height 90 cm. The performance at constant hydraulic head 261.67 m3/m2 per day while feed concentrations varied between 0.5-1, 0.5-1.5 0.5-2 mg/L, respectively. Coated seeds, covered plastic layer biofilm containing microorganisms, were used as material. carried out in single stage, which period two months required maturation bed. In optimal working conditions (QL = 8.11 L/h; pH 9.5; [Fe2+]0 2 mg/L; P 1.013 bar T 25±1° C; Redox potential 300 mV), operating cycle time 1 has proven to be sufficient bed backwash operation. results show that treatment gives reduction percentages 39.3, 48.76 67.23%, respectively boreholes Pout Kirène (PK2), Sud (PS5) Koungheul (KK5). Key words: Biofilm, continuous test, oxidation, removal, column, doped water.

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Cost-Effective Filter Materials Coated with Silver Nanoparticles for the Removal of Pathogenic Bacteria in Groundwater
The contamination of groundwater sources by pathogenic bacteria poses a public health concern to communities who depend totally on this water supply. In the present study, potentially low-cost filter materials coated with silver nanoparticles were developed for the disinfection of groundwater. Silver nanoparticles were deposited on zeolite, sand, fibreglass, anion and cation resin substrates in...

10 11 We demonstrate that electrocoagulation (EC) using iron electrodes can reduce arsenic 12 below 10 µg/L in synthetic Bangladesh groundwater and in real groundwater from 13 Bangladesh and Cambodia while investigating the effect of operating parameters that are 14 often overlooked, such as charge dosage rate. We measure arsenic removal performance 15 over a larger range of current density tha...
