BioDrill GreenScav Fe/FeQ

BioDrill® GreenScav Fe contains Fe (II) complexed with lignosulfonate, while Greenscav FeQ is an iron lignosulfonate. The presence of lignosulfonate enhances Fe (II) availability in solution to react with H2S, thereby increasing its scavenging efficiency compared to standard iron-based products. 

Superior performance of BioDrill GreenScav Fe/FeQ is observed versus ferrous gluconate as shown in the figure below. Read our technical bulletin to learn more.
