A novel cationic-modified chitosan flocculant efficiently

Especially in sewage flocculation, because cationic or non-ionic polyacrylamide cannot effectively flocculate particles in oil sands tailings, and anionic polyacrylamide limits its use in asphalt extraction process, the development of chitosan flocculant has important practical application value . The main research of this thesis is to carry

Evaluating dissolved air flotation for oil/water separation

Highlights ? An environment-friendly and cost-effective air flotation process was proposed. ? High oil removal was achieved using hybrid ferric chloride-chitosan dosing. ? Hybrid dosing reduced the usage of non-biodegradable ferric chloride by 90%. ? The addition of chitosan assisted the bridging and agglomeration of oil flocs. ?

Water treatment flocculation: Which flocculation agent is best?

Ferric sulfate (Fe (SO 4) 3)) is an iron-based salt that is one of the most widely used flocculants across different industries, along with alum and ferric chloride. It has slightly acidic properties that make it suitable for pH adjustment and is highly effective as a flocculant agent.

1. Introduction Water pollution results from all Human activities: domestic, industrial and agricultural, and is not only due to petroleum, minerals, sewage treatment sludge or persistent organic pollutants produced by the incineration of waste, but also to synthetic substances produced by chemistry (dyes, fertilisers, pesticides, and so on) [1].

Chitosan for direct bioflocculation of wastewater - Springer

In particular, chitosan and chitosan-based products have found applications as bioflocculants for the removal of particulate and dissolved pollutants by direct bioflocculation. Direct flocculation is done with water-soluble, ionic organic polymers without classical metal-based coagulants, thus limiting water pollution.
