PolyCera, a leading brand of PSP.US Inc, specializing in cutting-edge membrane technology, has announced its selection for the crucial second phase of a significant Salt Lake Lithium Extraction project in Tibet, China. This expansion will dramatically increase the project's total treatment capacity to over 100,000 cubic meters per day (m³/d).

This significant win follows the exceptional performance and positive feedback received from operators during the project's initial phase. In Phase 1, PolyCera successfully implemented an advanced membrane system boasting a capacity of 1,900 cubic meters per hour (m³/h). The project developers' decision to award PolyCera the second phase underscores their confidence in the company's innovative technology and proven expertise in tackling complex extraction challenges.

Scheduled for delivery by June 2025, Phase 2 will add an impressive 2,300 m³/h of additional capacity to the lithium extraction operation. This expansion will significantly enhance the output of lithium, a critical raw material essential to produce renewable energy storage solutions, such as batteries for electric vehicles, and other clean energy technologies. As part of this phase, PolyCera will provide a comprehensive membrane solution, encompassing elements, pressure vessels, and racks.

Jinwen Wang, Vice President of Product at PolyCera, highlighted the unique advantages of their technology in this challenging environment. “In this project, the PolyCera Hydro-UF membrane plays a crucial role in separating freshly formed magnesium hydroxide precipitates, which can reach concentrations exceeding 700 mg/L at a highly alkaline pH of around 13, from the valuable lithium-containing brine. Notably, this is achieved without the need for pretreatment, a testament to the superior chemical resistance and robust monolith module design of our membranes. Furthermore, the salt lake brine experiences very low temperatures, often dropping below 40°F in winter. Our PolyCera membrane operates efficiently at lower operating pressures compared to conventional membranes due to its inherent hydrophilicity and high water permeability, offering significant energy savings.”

Jianbo Wen, CEO of PolyCera, expressed his enthusiasm about the continued partnership. "We are deeply honored by this continued trust and recognition of our technology's capabilities," he stated. "Winning the second phase of this major lithium extraction project in Tibet highlights PolyCera's leadership in sustainable innovation and demonstrates our unwavering commitment to solving complex water and wastewater challenges on a global scale."

This landmark project directly addresses the growing global concerns surrounding lithium shortages, presenting a scalable and sustainable solution to the intricate challenges of lithium extraction from brine resources.
