In the industrial wastewater treatment sector, high efficiency often comes with high costs—expensive equipment, complex maintenance, and significant energy consumption. Ningbo Shangfuyuan Environmental Technology Co., Ltd. is challenging that narrative.
Founded in March 2015, the company is committed to transforming the environmental protection industry through a simple but powerful philosophy: high efficiency with low investment, high pollutant removal rates with low operating costs, and advanced technology with simplified processes.
Core Patented Technologies
Shangfuyuan’s competitive edge is built on a portfolio of patented technologies, including international patents. Here are three of their key innovations:
1. Minimalist High-Efficiency Air Flotation Machine
(China Patent ZL201821107514.7 | US Patent 10,947,130 B2)
This technology replaces traditional complex air flotation systems. Instead of relying on dissolved air tanks, releasers, and air compressors, it uses a standard centrifugal pump combined with a jet device to achieve air induction and bubble cutting. A specially designed tank eliminates the need for a scraper, and spiral piping replaces mechanical agitation.
The Result: Higher air flotation efficiency, smaller microbubble diameters, simpler operation and maintenance, lower engineering and operating costs, and a significantly smaller footprint.
2. Air Stripping Reflux and Sedimentation Device
(China Patent ZL201910063708.4 | European Patent (Germany) | India Patent Accepted)
This invention is a game-changer for biological treatment systems. The sedimentation module is installed directly inside the aerobic tank, eliminating the need for a separate secondary clarifier and return pumps.
The Core Process: Power-free, large-proportion sludge reflux from the top of the biochemical system to the bottom, and from the end back to the inlet. This design enables in-situ sedimentation separation and fosters the cultivation of aerobic granular sludge—a highly efficient form of biomass.
3. Ammonia-Containing Waste Gas Recovery and Reuse Device
(China Patent ZL202010191692.8)
This patent addresses air pollution and resource recovery simultaneously. It recovers ammonia nitrogen from waste gas and converts it into ammonium bicarbonate solution, which can be reused in power plant denitrification processes (replacing urea) or in total nitrogen removal processes.
Proven in the Field
Shangfuyuan’s technologies are not just theoretical—they are actively deployed in real-world applications across China. Their patents have been successfully applied in numerous projects, including:
-
High-Concentration Wastewater: Electro-catalytic enhancement and biochemical modification for Wenzhou Hongze Thermal Power.
-
Toner Wastewater: Modification and upgrading for Ningbo Frestech New Materials.
-
Machining Wastewater: 12 tons/day treatment for Ningbo Saimu Transmission Parts.
-
Food Waste & Kitchen Wastewater: Treatment equipment for Hangzhou Nanda Environmental Protection.
-
Bearing Wastewater: 20 m³/d treatment for Ningbo Bolin Bearing.
-
Battery Wastewater: Treatment project for Shanghai Lanjun New Energy Technology.
-
Surfactant Wastewater: Treatment for Ningbo Yuanli Chemical.
