Selection of the method for brine purification

The process of refining saltwater has evolved, from the early Dow clarification tanks to Gore membranes (or Porex membranes), and then to technologies such as KAI membranes today. It seems that only the KAI membrane technology remains now, and the price offered by this company is quite high; the initial investment is not low either. Let’s discuss the options available for refining brine at present, to see if it’s possible to break Ke Membrane Company’s monopoly. # ， ， &
Why isn’t anyone saying anything? I’ll speak first. In addition to the traditional clarification tank co-sedimentation process, saltwater purification technology has, since 2000, evolved into a landscape in which saltwater filtration technologies such as organic membranes (primarily HVM and GORE), inorganic membranes (Jiangsu Jiuguo High-Tech Jiusi Membranes), and Shanghai Xien coexist. HVM holds a high market share, estimated to be around 10 million tons (already in operation) ； GORE+PALL has been conducting intensive marketing efforts recently; thanks to its advantages such as high throughput and low suspended solids content, the number of its users is gradually increasing ； Jiusi Membrane has been in use at Xikangda Company in Hukou, Jiangxi for 9 months now ； Shanghai Xien has seen rapid growth in its customer base within China; it currently has customers in the field of diaphragm and ion-exchange membrane caustic soda, including Zigong Honghe, Gansu Jinchuan, Changzhou Xindong, Jintan Salt Chemical, Shandong Dacheng, and Xinjiang Tianye.
Our company uses Kai Membranes, and the results are excellent. The chlor-alkali industry is inherently a capital-intensive sector, and Kai Membranes’ dominant position is also due to its own strength! ! ! It’s difficult to shake its position! ! !
The number of users of Jiangsu Jiuwu Company’s inorganic membrane brine technology is also increasing; four new contracts were signed in 2007! Moreover, the company is very strong, backed by Nanjing University of Technology (formerly Nanjing Institute of Chemical Technology) – an academician of the Chinese Academy of Engineering
