Title: Innovations by Aiguo Wan: Pioneering Sludge Treatment Technologies

Introduction

Aiguo Wan, an inventive mind based in Shenzhen, China, has made significant strides in environmental protection through his innovative patents. With a total of six patents to his name, he has focused on developing methods that address pressing ecological challenges, particularly in sludge treatment and phosphorus removal.

Latest Patents

Among Aiguo Wan's latest innovations is a groundbreaking **method for the treatment of sludge**. This method involves a sophisticated sludge treatment system that incorporates a facultative digestion tank, a membrane module, an aeration system, a sludge pump, and a drainage pump. The process begins by pumping sludge into the facultative digestion tank for digestion. Simultaneously, the aeration system aerates and scours the membrane module. The sludge is then pumped through the drainage pump and filtered by the membrane module to separate sludge from water. This technique successfully addresses common issues in traditional sludge treatment, such as high investment and transportation costs, while achieving near-complete digestion and a zero-discharge of sludge.

Another noteworthy patent from Aiguo Wan is a **method for removing phosphorus**, which includes several critical steps. It begins with the placement of lanthanum oxide hydrate into a phosphorous removal device, allowing sewage with phosphorus content below 100 mg/L to flow through. When the device's absorption capacity is exhausted, sodium hydroxide is added as a regeneration solution, leading to a reaction that lasts between 4 to 12 hours. Subsequently, the eluate is collected and phosphorus is recycled, showcasing an efficient approach to managing phosphorus in wastewater.
