With a total of four patents to his name, Yuan has made significant strides in addressing critical environmental challenges.

Latest Patents

One of Yuan's latest patents is a method for the treatment of sludge. This method utilizes a facultative-organism-adapted membrane bioreactor, which includes a sludge treatment system comprising a facultative digestion tank, a membrane module, an aeration system, a sludge pump, and a drainage pump. The process involves pumping sludge into the facultative digestion tank, allowing for digestion, and synchronously aerating and scouring the membrane module. This innovative approach effectively separates sludge and water, achieving complete digestion and addressing issues such as high investment and transportation costs, ultimately leading to zero discharge of sludge.

Another significant patent by Yuan is a method for removing phosphorus. This method involves several steps, including placing lanthanum oxide hydrate into a device for phosphorus removal and allowing sewage with a phosphorus content of less than 100 mg/L to flow through the device. When the absorption capacity is exhausted, sodium hydroxide is added to regenerate the absorbent, allowing the regeneration reaction to proceed for 4 to 12 hours. The eluate collected can then be recycled for phosphorus, showcasing Yuan's commitment to sustainable practices.
