PLUMEM.PLUMEM, established in 2004 and headquartered in Hefei, is a high-tech enterprise holding over 100 proprietary intellectual property rights (including 40 invention patents). The company initially focused on membrane technology applications in specialized material separation fields such as biofermentation and natural product extraction, accumulating extensive expertise. Subsequently, its business successfully expanded into high-difficulty industrial wastewater treatment, forming a dual-drive model centered on “fluid membrane separation” and “zero-discharge wastewater treatment/resource recovery.” Its core strength lies in the independent development of the breakthrough PEK tubular membrane. Building upon this foundation, the company has created multiple specialized process packages that effectively address technical challenges such as hardness removal, oil removal, and heavy metal removal. Its products and services are widely applied across various sectors including oilfields, coal chemical processing, landfill leachate treatment, and lithium extraction from salt lakes, achieving large-scale industrial application of its technological achievements.
