Oxidation
Use chemical oxidation for the non-biodegradable inert COD.
At Nippon Gases we are called “The Gas Professionals” for a reason, and it’s because we’ll be able to solve any doubt.
Ozone to increase organic matter removal
Ozonation is an effective and efficient method to eliminate inert organic matter that can not be eliminated biologically (recalcitrant, refractory). With a tertiary treatment of ozonation it’s possible to reduce the COD of the effluent to comply with the current legislation, or to reach the water quality parameter values for industrial water reuse.
Ozone
Estimate and minimize de O3 dosage through experimental testing.
Color removal
Tertiary treatment advanced oxidation removes color from the treated water.
Nippon Gases carries out specific studies to analyse the technical and economic viability of ozonation in industrial water.
