The successful commissioning of the Liaoning Oil Wastewater Treatment Project, designed and delivered by Zhengzhong Technology, marks a new milestone in the company’s commitment to environmental protection and sustainable industrial development. As another benchmark project in Zhengzhong’s portfolio, it highlights the company's leadership in advanced environmental equipment manufacturing, particularly in the application of Fusion Bonded Epoxy (FBE) Tanks.
These tanks, independently designed and produced by Zhengzhong Technology, serve as the core storage and processing components of the treatment system. Their deployment not only reinforces operational stability but also provides vital technical support to the green transformation of the petroleum industry, aligning with national goals for energy conservation and emissions reduction.
Breaking the Limits of Traditional Materials
Oil and petrochemical wastewater presents one of the most challenging treatment scenarios across industries. It often contains high concentrations of organic pollutants, heavy metals, sulfides, and other corrosive substances. Conventional materials such as carbon steel and even stainless steel often fall short under such harsh conditions. Corrosion damage, leakage risks, high maintenance costs, and short service lifespans are common issues that compromise both environmental safety and cost-efficiency.
By contrast, the Fusion Bonded Epoxy Tanks developed by Zhengzhong Technology offer a next-generation solution to these longstanding problems. With their superior chemical resistance, lightweight but high-strength structure, outstanding sealing performance, and flexible design capability, these tanks are proving to be ideally suited for demanding wastewater treatment applications—especially in the petrochemical sector.
Engineered for Harsh Conditions
For the Liaoning project, Zhengzhong Technology selected high-performance epoxy resin materials based on the unique chemical properties of the wastewater and the operating conditions at the site. Each tank is engineered to maintain long-term stability and integrity under high-humidity, highly corrosive environments typical of oil and gas operations.
In addition to their corrosion resistance, the tanks offer robust structural stability, meeting the specific needs of the onsite treatment processes. The tanks can handle fluctuations in temperature, pressure, pH levels, and chemical concentration, ensuring long-term performance with minimal maintenance.
Customized Solutions for a Complex Treatment System
The oil wastewater treatment system designed for this project consists of several integrated processes, including:
Oil-water separation
Chemical flocculation
Flotation treatment
Biological processing
Advanced filtration
Zhengzhong’s FBE tanks play a vital role across these stages, serving as raw water buffer tanks, chemical reaction tanks, flocculation tanks, intermediate water tanks, and clean water storage tanks.
To ensure complete system integration, each tank was custom-designed in terms of volume, internal structure, and connection interfaces. Design parameters such as flow rate, fluid temperature, chemical composition, and treatment duration were meticulously analyzed to tailor tank configurations to the unique requirements of each process stage.
Additional features include:
Dedicated inlet/outlet nozzles
Level gauge interfaces
Anti-corrosion linings
Manholes for inspection and maintenance
This level of customization guarantees seamless compatibility with the overall system, while ensuring optimal performance, reliability, and safety.
Energy-Efficient, Eco-Friendly, and Built for the Future
Compared to conventional steel tanks, Zhengzhong’s Fusion Bonded Epoxy Tanks offer a range of environmental and operational advantages:
Lower energy consumption during production
Longer service life under harsh chemical conditions
Lower maintenance costs due to superior corrosion resistance
Reduced risk of secondary pollution caused by leakage or material degradation
These tanks improve not only the efficiency and safety of wastewater treatment systems but also actively support green industrial development. From the initial manufacturing stage to system integration and long-term operation, Zhengzhong’s tanks are designed to minimize environmental impact throughout the entire product lifecycle.
A New Industry Standard for Wastewater Treatment
As environmental regulations grow stricter, industries such as petrochemicals, pharmaceuticals, food and beverage, printing, and dyeing are placing higher demands on wastewater treatment infrastructure. In particular, there is a rising need for equipment that excels in corrosion resistance, pressure handling, long-term durability, and operational safety.
Fusion Bonded Epoxy Tanks, as an innovative composite material solution, are emerging as a next-generation alternative to traditional steel tanks. Their versatility, modular design, and material advantages allow them to be widely used in treatment systems that handle fluids containing acids, alkalis, salts, as well as those with high Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels.
The successful deployment of these tanks in the Liaoning project serves as a powerful case study and technical validation. It also sets a new benchmark for the wastewater treatment industry.
Continuing the Mission of Green Innovation
Building on the success of the Liaoning project, Zhengzhong Technology plans to further expand the application of epoxy resin tanks across a broader range of environmental protection projects. As industrial enterprises face growing pressure to reduce their carbon footprint and improve environmental compliance, the demand for advanced, durable, and sustainable treatment equipment will only increase.
Zhengzhong remains committed to leading this transition by continuously enhancing the technical capabilities of its composite material equipment and supporting a low-carbon future for China's industrial sectors.
Conclusion: A Commitment to Sustainability and Excellence
Green development is no longer just a trend—it is a shared responsibility among all modern industrial enterprises. With every successful project, Zhengzhong Technology is reinforcing its position as a leader in environmental protection equipment, delivering innovative, reliable, and sustainable solutions that serve both industrial performance and ecological preservation.
