Under the increasingly stringent environmental regulations and the global push toward carbon neutrality, the industrial wastewater treatment industry is undergoing a profound transformation. The traditional model—characterized by high capital investment, excessive energy consumption, and low economic returns—is no longer viable. What the market urgently needs are innovative solutions that truly deliver cost reduction and efficiency gains.

Ningbo Shangfuyuan Environmental Technology Co., Ltd., established in March 2015, has been committed to solving this exact problem from day one. By relentlessly focusing on technological innovation and process optimization, the company has developed a series of internationally recognized patented technologies that offer fresh, practical answers to the most stubborn challenges in industrial wastewater treatment—across sectors such as chemicals, pharmaceuticals, pesticides, and papermaking.

The Victory of Minimalism in DAF Technology

In the solid-liquid separation stage, conventional Dissolved Air Flotation (DAF) systems are notoriously complex. They rely on saturators, air compressors, release devices, and mechanical scraper mechanisms—resulting in large footprints, high energy consumption, and costly maintenance.

Shangfuyuan’s patented “Extremely Simplified High-Efficiency DAF Unit” revolutionizes this process. By ingeniously combining a standard centrifugal pump with an ejector, the system uses venturi suction and impeller shearing to generate fine microbubbles—completely eliminating the need for saturators, release devices, and air compressors. Additionally, its specially designed tank geometry and spiral piping replace mechanical stirrers and sludge scrapers.

The results speak for themselves:

• Finer microbubbles for superior flotation efficiency

• Self-operating scum discharge and enclosed operation

• Significantly lower capital expenditure, operational costs, and footprint

This breakthrough has earned not only domestic recognition but also a U.S. utility patent, validating its novelty on the global stage.

Empowering the Biological Core: Air-Lift Reflux and Sedimentation

While the DAF patent addresses upfront physical separation, Shangfuyuan’s second flagship innovation targets the heart of biological treatment—the activated sludge process.

Traditional systems require a separate secondary clarifier and mechanical sludge return pumps, which increase infrastructure costs and, more critically, the pump impellers tend to shear and damage fragile flocs, reducing treatment efficiency.

The patented “Air-Lift Reflux and Sedimentation Device” elegantly solves this by integrating the sedimentation module directly inside the aeration tank. Using the very aeration air as the driving force, it achieves large-ratio sludge reflux without additional power. This design:

• Eliminates the need for separate clarifiers and return pumps

• Provides gentle hydraulic conditions that promote the cultivation of aerobic granular sludge (AGS)

Remarkably, Shangfuyuan has successfully cultivated AGS in real industrial and high-salinity wastewater streams—a testament to the system’s robustness and advanced capabilities. This technology has been granted a Chinese invention patent, a European patent (validated in Germany), and is under examination in India.

From Waste to Resource: Ammonia Recovery Innovation

Beyond purification, Shangfuyuan also addresses resource recovery with its patented “Ammonia-Containing Exhaust Gas Recovery and Reuse Device.”

This system captures ammonia from exhaust streams and converts it into ammonium bicarbonate solution (with some ammonium carbonate)—a valuable byproduct. This solution can directly replace expensive urea in power plant denitrification (SNCR/SCR) processes, or serve as a carbon/nitrogen source for total nitrogen removal in biological systems.

In doing so, the company turns an environmental liability into an economic asset—a true win-win for both compliance and profitability.

Proven Performance Across Industries

These three patented technologies are not lab-scale concepts; they have been repeatedly validated in full-scale engineering projects. Notable clients include:

• Wenzhou Hongze Thermal Power Co., Ltd.

• Ningbo Finesun New Material Co., Ltd.

• Hangzhou Nanda Environmental Technology Co., Ltd.

• Shanghai Lanjun New Energy Technology Co., Ltd.

The projects cover a wide spectrum of challenging wastewaters—high-concentration organic, machining/cutting fluid, food waste digestate, battery manufacturing, and surfactant effluents. In every case, the Shangfuyuan solutions have demonstrated higher treatment efficiency, lower operating costs, and remarkable operational stability, delivering tangible value to clients.
