Enhanced Coagulation-Flocculation Performance of Iron-Based Coagulants: Effects of PO43- and SiO32- Modifiers

PO4(3-) and SiO3(2-) are often used as modifier to improve stability and aggregating ability of the iron-base coagulants, however, there are few reports about their detailed comparison between the coagulation performance and mechanisms. In this study, three coagulants--polyferric phosphoric sulfate (PFPS), polysilicon ferric sulfate (PFSS), and polyferric sulfate (PFS) were synthesized; their s...

Coagulation and Flocculation Treatment of Wastewater in Textile Industry by Using Chitosan

Aluminum sulfate (alum), ferrous sulfate, ferric chloride and ferric chloro-sulfate were commonly used as coagulants. However, a possible link of Alzheimer’s disease with conventional aluminium based coagulants has become an issue in wastewater treatment. Hence, special attention has shift towards using biodegradable polymer, chitosan in treatment, which are more environmental friendly. Moreove...

Flocculation of kaolin by waxy maize starch phosphates

Waxy maize starch phosphates were tested as flocculants in order to determine if they have the potential to replace petroleum-based polymer flocculants currently used commercially. Phosphorylation was carried out by dry heating of starches and sodium orthophosphates at 140 C for 4 h. Native and phosphorylated waxy maize starches were ineffective as flocculants for kaolin in deionized water. How...

Mechanistic Insight into the Coagulation Efficiency of Polysaccharide-based Coagulants

Polysaccharides possess the highest industrial capacity for adsorbents that can be useful as eco-friendly materials for water treatment, due to their prevalence [1–3]. Polysaccharides are stereoregular (natural) polymers of monosaccharides (sugars) also referred to as biopolymers. They are unique raw materials because they are inexpensive and widely available in many countries in the world. The...
