This study developed a coagulationflotation process for microalgae chlorella sp.Xj-445 harvesting, which was composed of algal surface modification by combined use of al 3 and cetyltrimethylammonium bromide ctab and followed dispersed bubble flotation.Dissolved organic matter dom in the medium was firstly characterized and mainly consisted of hydrophilic low molecular weight molecules.
Selected studies illustrating well the use of biopolymers to induce natural flocculation are compiled in table 1.The most popular biopolymer used for microalgae flocculation is chitosan.Chitosan is a cationic polyelectrolyte obtained by deacetylation of chitin, and after cellulose, it is the second most abundant natural polymer in the world.
Hematite wikipedia.Hematite also spelled as haematite is a common iron oxide with a formula called fe 2 o 3 and has been widespread in rocks and soils hematite forms in the shape of crystals through the rhombohedral lattice system and it has the same crystal structure as ilmenite and corundumhematite and ilmenite form a complete solid solution at temperatures above 950 c 1 740 f.
