Nitrate removal

The removal of nitrate from aqueous solutions of a synthetic medium and groundwater was examined using various aquatic plants, such as water hyacinth, water lettuce and salvinia. Water hyacinth reduced the nitrate level to 64% in a synthetic medium containing 100 mg l–1 of nitrate. The efficiency of

The removal of nitrate ions through SB-6407 and Neosepta AMX anion exchange membranes has been studied under Donnan dialysis conditions as a function of receiver phase concentration and co-existence anions in the feed phase. For both membranes, it was observed that the transport of nitrate increased

This work aims to explore the use of an innovative denitrification process developed by our group for groundwater remediation. This process is coupling heterotrophic-autotrophic denitrification processes (HAD) supported by cotton and zero-valent iron (ZVI). In the experimental part, the effect of tw

The removal of nitrate from contaminated groundwater via polyelectrolyte-enhanced ultrafiltration (UF) was investigated using different chelating polymers and membrane pore sizes. Although the percentage polymer rejection by membranes slightly decreased with higher chelating polyelectrolyte dosages,
