Ozone Treatment

Aurozon offers Ozone Treatment. It is used to discolour and detoxify effluents using ozone. Ozone should be applied to remove the colour, odour, COD/ BOD, etc. Ozone can be used in two stages for more effective result: to remove colour from wash water, the ozone dosing required is from 50 to 150 ppm depending on the toxic concentration. pH should be optimised for better results. The ozonated water has to be passed through a clarifier to separate the suspended solids. A trace quantity of alum and polyelectrolyte is also added for more effective removal of the existing suspended solids and abatement of the turbidity. The solid waste, if any, which comes out from the settling tank is incinerated. The turbidity will thereby reduce from 20 to less than 4 NTU. There is no hazardous chemical sludge generated. The COD level after ozone treatment is much less when compared with chemical treatment. The colour and odour are completely removed by ozone. The effluent gets fully sterilised.
