Enhanced Fenton Equipment

1.Principle of the Device & Application Scenarios

Application Scenario: As an advanced oxidation process, the "Enhanced Fenton" technology is widely used in the treatment of various industrial wastewaters. It can serve as a wastewater pretreatment method to reduce the concentration of sewage and improve its biodegradability. It can also act as an advanced treatment means for wastewater to meet discharge standards, capable of removing organic substances, chromaticity, nitrogen, phosphorus, and heavy metals (such as antimony).

Kaifa Intelligent has two types of equipment for selection: "Fluidized Bed Fenton" (left in the figure below) and "Rotary Mixing Fenton" (right in the figure below).

The "Fluidized Bed Fenton" has a complex structure and adopts forced circulation by a water pump. Although its investment cost is slightly higher, it features good treatment efficiency, small sludge output, and reduced chemical consumption, thus resulting in lower operating costs.

The "Rotary Mixing Fenton" has a simple structure and does not require water pump circulation, relying only on air. It boasts good mass transfer performance and low investment cost. Although its treatment efficiency is slightly inferior to that of the "Fluidized Bed Fenton", it can still improve the treatment effect by more than 30% compared with ordinary Fenton processes.

2. Equipment Advantages 

• More extensive application experience. We have over 100 cases in industries such as chemical wastewater, oil refining wastewater, and printing and dyeing wastewater. During the application process, we have summarized a complete set of operational experience of this technology in different types of sewage, enabling users to apply the technology more safely and stably.

• Better improvement and optimization. We have made improvements and optimizations in aspects such as water distributors, pH adjustment, and equipment anti-corrosion upgrades, so as to ensure users' experience (reducing maintenance workload) and guarantee the service life of the equipment to be 20-30 years.

• Upgrades in automation and intelligence. Based on AI applications, we have developed an "Enhanced Fenton" operation platform. This platform can integrate historical data on influent COD, effluent COD, and chemical dosage during operation, and derive a reasonable algorithm to optimize operating parameters, which are then fed back to the automatic chemical dosing device. Through this technology, the operating chemical cost can be reduced by 20-30%, which represents a continuous revenue stream and achieves green and carbon reduction effects.
