Natural organic matter (NOM) is a complex matrix of organic substances produced in (or
channeled to) aquatic ecosystems via various biological, geological and hydrological cycles …

Adsorption by activated carbon has great potential to improve natural organic matter (NOM)
removal from water. However, the high production and regeneration costs limit its wide scale …

Coagulation-flocculation has been applied widely in water and wastewater treatment.
Tannin, a natural water-soluble polyphenol that is present in most vegetable cells, has been …

The ever-growing water pollution evokes the inevitability of disinfection, especially by
chlorination from decades, although the emergence of many carcinogenic disinfection by …

More and more efforts are being made to find efficient bio-based water and wastewater
treatment products. Especially the use of tannin-based materials has become more …

Population growth, industrialization, urbanization, and agriculture lead to a decrease in the
availability of clean water. Coagulation/flocculation is one of the most common operations in …

This study explored the potential for using tannin extract from spruce bark (Picea abies) as a
coagulant. Spruce tannins were extracted with hot water and pulverized through spray …

In municipal wastewater treatment, inorganic coagulants (IC), eg polyaluminium chloride
