Successful Cases Reference
Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
The application of desalination membranes on international luxury cruise ships has historically been dominated by a few international brands. The quality of feed water, such as salinity and temperature, fluctuates with the cruise ship's journey. Therefore, the membranes must adapt to different conditions while ensuring stable water production to meet the needs of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes demonstrated superior performance in both desalination rate and stable water production. The water quality produced by these membranes met the stringent requirements of the cruise ship.
This remarkable result led to the replacement of desalination membranes on three additional cruise ships. Proshare's success in this venture establishes it as the first national brand to win international luxury cruise ship orders for desalination RO membranes.
A Complete Water Treatment Plant for Generating Ultra-pure Water in Semiconductor Industry
The demand for electronic-grade ultra-pure water in the semiconductor industry is exceptionally high, and very few brands can meet these rigorous standards.
By harnessing Proshare's groundbreaking TFN membrane technology and the TsingXi team's extensive expertise in water treatment, our comprehensive water treatment plant and pure water equipment solutions deliver outstanding rejection rates for salt, boron, and TOC. This ensures that the system's water production meets the stringent requirements of the semiconductor industry.
This positive outcome secured us a project for electronic ultra-pure water treatment with a renowned Japanese listed company.
Proshare Tailor made TFN special acid-resistant and high-pressure membranes for Wastewater Treatment in Petrochemical / Refining to Truly Achieve Zero Liquid Discharge
Proshare Tailor made TFN special acid-resistant and high-pressure membranes separation and concentration device for wastewater treatment containing ammonium sulphate desulphurisation. It achieved wastewater concentration up to 40 times with ammonium sulphate concentration ≥ 20% in the concentrated water. This significantly reduces energy consumption for subsequent evaporation and crystallisation, leading to substantial cost savings for users. The water quality consistently meets the China Petroleum and Chemical Corporation's corporate standard Q/SH 0628.2-2014 for circulating water make-up, with true zero wastewater discharge achieved.
This positive result has garnered additional orders from other subsidiaries in the group.
This membrane is also applicable to other high-temperature, highly acidic wastewater scenarios containing ammonium sulphate, such as in the energy, refining, chemical, and metallurgical industries. The latest developments in ammonia desulphurisation technology combined with carbon capture support new energy consumption and the development of the green industry chain, aligning with the national 'dual-carbon' policy.

Proshare Pioneering Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously crafted the next era of reverse osmosis membranes, leveraging the revolutionary polymer interface nano-self-assembly technology. This advancement triumphs over the age-old constraints of traditional reverse osmosis membrane development with two pivotal innovations:
Revolutionary Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, the team has adeptly minimized the separation layer's thickness to a striking one-third of the conventional polyamide thin film (historically capped at 100 nm). This monumental advancement dramatically boosts water flux, delivering unparalleled improvements in permeability.
Superior Enhanced Performance: The innovative integration of nanoparticles with specialized hydrophilic polymers has paved the way for remarkable advancements in the membrane's hydrophilicity, anti-fouling prowess, unparalleled durability, and robust oxidation resistance.
When compared to conventional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases strides in four crucial dimensions:
Ingenious Self-Assembled Nanocomposite Films
Through the meticulous integration of nano-scale precision control and nano-doping modification, we craft ultra-thin and highly ordered separation layers via advanced polymer interface nanotechnology. This methodology transcends the conventional polyamide membrane's limitations in maintaining thickness uniformity and material diversity.
Augmented Water Flux and Revolutionary Energy Efficiency
By refining the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a remarkable threefold reduction compared to traditional membranes, thereby resulting in over three times the water flux efficiency and a 30% reduction in energy consumption.
Innovative Polymer Materials Boasting Superior Chemical Stability
Moving beyond the simple polyamide, our team employs cutting-edge hydrophilic polymers (for example, modified polysulfones) and pioneering ceramic-organic hybrids. These materials exhibit outstanding oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and broad pH tolerance (remarkably stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The ultra-superhydrophilic surface (with a contact angle less than 10°) reinforced by nanoparticles diminishes organic fouling by 50%, doubling the chemical cleaning cycle from three to six months, slashing maintenance expenses by 40%.
Our commitment to excellence is underscored by our array of prestigious certifications. We boast a Health & Safety Management System Certificate, ensuring top-notch safety protocols.
