Product Introduction
A perfect fusion of advanced ozone oxidation and cyclonic dissolved-air flotation
What isCDOF？
CDOF(Cyclonic Dissolved Ozone Flotation) is SINOKLE's proprietary patented product, which creatively integratesadvanced ozone oxidation technology、cyclonic technologyanddissolved-air flotation technologythrough organic integration to achieve highly efficient comprehensive removal of various refractory wastewaters.
This unit integrates ozone multi-catalytic oxidation, hydrodynamic cavitation, and cyclonic flotation technologies. It is a domestically original, internationally leading high-efficiency integrated oxidation and flotation device capable of rapidly and efficiently removing petroleum, suspended solids, colloids, COD, bacteria, and various other pollutants from wastewater.
Working Principle
Multi-stage, multi-dimensional, multi-catalytic oxidation reaction system
Ozone Generation and Dosing
The oxygen generation system produces high-purity oxygen, which is converted into ozone by the ozone generator; the efficient dosing system mixes the ozone gas with the wastewater.
Multi-catalytic Oxidation
Homogeneous and heterogeneous catalysts work in synergy to generate abundant hydroxyl radicals (OH) with an oxidation potential of 2.80 V, efficiently degrading organic matter.
Cyclonic Flotation Separation
Cyclonic centrifugal force and micro-nano bubbles work synergistically to rapidly separate and remove suspended solids, colloids, and scum.
Exhaust Gas Destruction and Discharge
Ozone-containing tail gas is treated by the tail-gas destructor to meet standards before discharge; fully enclosed operation with zero leakage.
