Specific features of organic coagulants

The organic coagulant (type 2 cationic polymer) with a strong cationic nature provides a coagulation mechanism fairly close to the metallic coagulants mechanism but does not include the subsequent flocculation stage. 

As a matter of fact, this arbitrary explanation summarizes complex phenomena which are still not very well understood. They can be mastered only by experience or, even better, by experimenting and testing (jar tests). 

In industry, this form of flocculation coagulation where coalescence prevails can be 

There are several important rules on the use of cationic coagulants  

Some organic coagulants can be listed Kemazur 4516 and 4521, Cyanamid 507, Nalco 3364, Alchem 7607, Tetrolite J 121 and WC 14-Direct demulsifiers
