Ozonators are a eco-friendly way of treating the water after final stage carbon filter outlet .The ozone gas is generated through a generator and dosed by a ventury mechanism directly into final treated water tank..This helps in disinfection and improves odour of STP treated water. Ozone is almost 1.5 times effective then chlorine and it has short life cycle which means it immediately oxidizes anything that comes in contact with it and has much wider reach for disinfection than traditionally used chlorine.
