Dioxide Generator EMEC LOTUS ULTRA

Dioxide Generator EMEC LOTUS ULTRA is the largest product among EMEC Chlorine Dioxide generators and is used in all those cases in which there is need of a big production, such as large water treatment plants.

Chlorine Dioxide is produced from concentrated base chemicals: acidchlorite process by hydrochloric Acid (HCI 33%) and Sodium Chlorite (NaCIO 27%)

Chlorine dioxide produced by LOTUS ULTRA is set to be proportional to the circulating water flow or based on a setpoint, it is then dosed into the water flow.

Max capacity: 2000 g/h
