Recently, the invention patent titled "A MOBR Device and Process for Advanced Nitrogen Removal from Wastewater" (Patent No.: ZL202411532907.2), developed by Shandong Shuifa Youmo Technology Co., Ltd., a subsidiary of Shandong AMS Environment Co., Ltd., has been authorized. This patent represents a technological breakthrough in the field of advanced nitrogen removal from wastewater, providing an efficient solution for the treatment of high-difficulty wastewater.

As an affiliated enterprise of Shuifa Group, Shuifa Youmo has been deeply engaged in the membrane-based water treatment field for many years. The authorized MOBR device and process innovatively integrates membrane aeration, membrane bioreaction, and sludge-water separation functions into one. Through a special structural design, an OAO microenvironment is constructed inside the reactor, enabling nitrifying bacteria and denitrifying bacteria to act synchronously and efficiently, which significantly improves nitrogen removal efficiency. The core parameters of the device exhibit excellent performance: the total nitrogen removal rate can reach over 95%, the COD removal rate exceeds 98%, the water production flux is maintained at 15-25 L/m²·h, and the aeration flux is stabilized at 30-50 L/m²·h.

Addressing the pain points of traditional equipment such as easy membrane fouling and attenuated treatment efficiency, the patent designs an exclusive cleaning and sewage discharge mechanism: the exhaust pipe and exhaust holes mounted on the strip box are used for precise cleaning of the membrane, while the sewage discharge mechanism isolates impurities, effectively ensuring the long-term stable treatment efficiency of the membrane. In the engineering demonstration at the No.1 Sewage Treatment Plant of Pingyin Water Affairs Development Co., Ltd., the technology demonstrated outstanding economic efficiency: the carbon source consumption is as low as 0.006 CNY/mg.TN, the power consumption is only 0.015 kWh/mg.TN, and the macro dissolved oxygen is controlled below 1 mg/L, greatly reducing the operating costs.

This technology can be widely applied in fields such as municipal wastewater treatment and industrial wastewater treatment, and is particularly suitable for high-difficulty wastewater treatment scenarios. Compared with traditional processes, it has significant advantages including small footprint, low operating costs, and thorough pollutant removal. As a professional R&D and manufacturer of membrane products, the authorization of this invention patent for the new MOBR membrane technology further consolidates Shuifa Youmo's technological leading position in the membrane-based water treatment field. The company will accelerate the industrialization of this technology, continuously promote the upgrading of water treatment technologies and import substitution, and provide more competitive solutions for the ecological and environmental protection industry.
