Under the conditions of Cl O2 dosage 15m L·L- 1, concentration of 20%, oxidation reaction time 20 min and initial wastewater COD was 1883.7mg·L- 1, the COD removal rate was 78.1%. In order to achieve the ideal ,treatment, effect, a certain amount of the composite metal catalyst was added into the ,flow-back, ...

Hydraulic fracturing - Wikipedia
Hydraulic fracturing - Wikipedia

As the fracturing process proceeds, viscosity-reducing agents such as oxidizers and enzyme breakers are sometimes added to the fracturing fluid to deactivate the gelling agents and encourage flowback. Such oxidizers react with and break down the gel, reducing the fluid's viscosity and ensuring that no proppant is pulled from the formation.
