MIX AGITATORS
                
Mixing operations and flow equalization, coagulation and flocculation, among others, are operations frequently performed in the process of waste wastewater treatment.

Depending on the type of operation that must be carried out, the selection of mixer and its speed are essential for the optimal operation of the system.  Mixers are chosen on the base of laboratory experiments and the experiences had in this area.

Design of mixing equipment

The factors that bear on the selection of mixing equipment are.

1) Requirements of the process
            These are:
                        Coagulation
                        Flocculation
                        Mix
                        Dissolution
2) Flow properties of the liquids in process
3) Cost of the equipment                    
4) Materials for the fabrication of these
