Do you know which of the seven commonly used chemicals for water treatment?

(1) Nanomaterials have small size effect, surface effect, quantum size effect, macro quantum tunnel effect, etc., as a new high-efficiency water treatment agent, they are placed on high hopes. At present, the use of nano TiO2 photocatalytic degradation of toxic organic matter, carbon nanotube modification to remove heavy metals and other research has made a breakthrough, which has set a precedent for the development of nanomaterial water treatment agents. 

 (2) Microbial flocculants are non-toxic biomolecular compounds, including functional proteins or functional polysaccharides, with unique properties of biodegradation. Compared with other flocculants, microbial flocculants have the advantages of easy solid-liquid separation, less precipitate formation, easy to be degraded by microorganisms, non-toxic and harmless, and strong practicability. At present, there are many researches on microbial flocculants, and some researchers have used inorganic - organic polymer flocculants in combination, and achieved good results.
