Rongjiang Town, located in the northern part of Guangxi, has a total population of approximately 30,000 including the town and surrounding villages. The domestic drinking water for residents is supplied by the town's water supply company. The raw water source comes from a mountain reservoir — a surface water source that has never dried up for many years. However, the raw water contains various bacteria and viruses, making it unable to meet drinking water standards. The leadership of the water supply company was troubled by this issue. After extensive searching, they learned that our company, Julin Technology, specializes in the water treatment industry and also deals in chlorine dioxide disinfectants specifically used for drinking water disinfection. They contacted us for detailed information on the usage of chlorine dioxide disinfectant.

Guangxi Nanning Xinliang Food Co., Ltd., formerly known as Nanning Xianyige Rice Noodle Factory, is a subsidiary of the Southern Food Group and has now been acquired by COFCO Corporation. The company specializes in the production and sales of fresh wet rice noodles, covering a wide geographical area and serving numerous consumers. To ensure product quality, the person in charge of Xinliang Company made significant improvements to equipment and also conducted extensive comparisons of disinfectant consumables used in production. Years ago, when food regulatory authorities still permitted food processing enterprises to use traditional disinfectants such as sodium peroxyacetate or strong chlorine disinfectants, these substances were later detected as potentially carcinogenic, affecting food safety. Consequently, such disinfectants were prohibited for use in food production and processing enterprises.

Hechi Qinlequan Natural Spring Water Co., Ltd. has been specializing in the production and sales of barreled mountain spring water for over 10 years, making it a relatively early entrant in the barreled water production industry in the Hechi area. With societal development, the coverage of end consumers has become increasingly extensive. However, the management of returned barrels has been rough, leading to severe contamination — a common challenge faced by all barreled water production enterprises. For over a decade, barreled water producers have used chlorine dioxide disinfectant for sanitizing returned barrels, but most have encountered issues such as non-standard operating procedures, insufficient concentration of chlorine dioxide disinfectant, and some small enterprises even resorting to disinfectants like strong chlorine agents instead of chlorine dioxide, which is strictly prohibited by regulatory authorities.

As a nationally renowned brand, Wanglaoji Herbal Tea has branch factories or production centers throughout the country. Its production center in Guangxi is precisely Zhuangfang Biotechnology Co., Ltd. Zhuangfang Biotechnology originally used purified water equipment that was not manufactured locally, which suffered from poor operational stability, resulting in severely disconnected after-sales service. Later, through introductions from associates, they learned that our company, Julin Technology, specializes in manufacturing purified water equipment and industrial water purification equipment, and contacted us. The project manager from Zhuangfang Technology visited our production workshop where purified water equipment is manufactured, gaining a detailed understanding of the applications and process flow of the purified water equipment produced by Julin Technology. They carefully compared the welding craftsmanship of our purified water equipment and discovered that our company's weld seams were smoother, flatter, and more aesthetically pleasing.
