Key Features:

• Achieve 30% lower pressures :Ensures exceptional salt rejection with 30% lower pressures, enhancing efficiency.
• Reduced Cleaning Frequency:Our TFN membrane's outstanding anti-fouling performance significantly reduces microorganisms and inorganic pollutants, resulting in less frequent cleaning requirements.
• Wide Cleaning pH Range (1-13):Delivers superior cleaning effectiveness, robustness, and durability, thanks to its extensive cleaning pH range and excellent chemical resistance.

Key Applications:
Ideal for softening, producing pure water, and water reuse across
pharmaceutical, electronics, power, petrochemical, refinery, food & beverage, municipal sectors, etc.

A common issue with RO membrane elements is fouling. Fouling doesn't alter the structure of RO membrane elements, but the foulant on the membrane surface can drastically diminish its performance.
prevents fouling by applying a proprietary hydrophilic coating on the membrane surface, ensuring long-term stable operation. By effectively preventing fouling, the reduced cleaning frequency ultimately contributes to lower operational expenses (OPEX) at the water treatment plant.
technology is the ideal choice for treating urban sewage water in industrial applications.

Farming applications

Water plays a crucial role in ensuring the health and productivity of livestock such as cattle, chickens, sheep, and pigs. However, it's not only the quantity that matters; the quality of the water is equally important in achieving optimal growth and performance of the animals.
The water used in farming can originate from a variety of sources, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources. Each source presents unique challenges and opportunities for water management.
Apart from civil networks, which often contain free chlorine, alternative water sources tend to have high levels of dissolved and suspended solids, as well as pathogens. Reverse osmosis technology emerges as the most effective solution, reducing these contaminants to ensure the safety and health of farm animals. It is essential for farms to implement technological treatments to mitigate harmful substances in the water.

 

Sucessful Application

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, international luxury cruise ships have relied heavily on a limited number of acclaimed international brands for their desalination membrane needs. With the voyage of these ships, the salinity and temperature of feed water fluctuate, demanding membranes that can seamlessly adjust to varying conditions while maintaining a steady output of water that satisfies the high demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes from Proshare shone with exceptional desalination efficiency and unwavering stability in water production. This ensured that the resultant water quality surpassed the rigorous criteria set by cruise ships.
This outstanding achievement led to the adoption of our desalination membranes on three more cruise ships. Proshare has thus set a new benchmark as the pioneering national brand securing orders from international luxury cruise ships for desalination RO membranes.

Our Advantages

Proshare Team's Remarkable Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has brilliantly developed a cutting-edge generation of reverse osmosis membranes, leveraging the revolutionary polymer interface nano-self-assembly technology. This innovation triumphs over the traditional limitations of reverse osmosis membrane development through two groundbreaking advancements:
Ultra-Thin Separation Layer: Through the application of advanced polymer interface nanotechnology, the team has successfully diminished the separation layer's thickness to an impressive threefold thinner than the conventional polyamide thin film (which was previously constrained to 100 nm). This monumental breakthrough not only amplifies water flux but also brings about a marked enhancement in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles along with specialized hydrophilic polymers has propelled unprecedented advancements in the membrane's hydrophilicity, anti-fouling properties, longevity, and robust oxidation resistance.
When compared to conventional polyamide reverse osmosis membranes, Proshare's innovation reveals breakthroughs in four pivotal domains:
Self-Assembled Nanocomposite Films
By merging nano-scale precision control with nano-doping modification, we achieve the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This method overcomes the inherent limitations of conventional polyamide membranes, particularly in thickness uniformity and material diversity.

Enhanced Water Flux and Energy Efficiency
Optimizing the layer-by-layer self-assembly process allows precise control over the functional layer thickness, resulting in an impressive 3x reduction compared to traditional membranes. This innovation leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the confines of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials offer exceptional oxidation resistance (capable of withstanding up to 10 ppm chlorine exposure) and pH tolerance (demonstrating stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface design (featuring a contact angle <10°) in conjunction with nanoparticle reinforcement significantly curtails organic fouling propensity by 50%. This innovation extends chemical cleaning cycles from 3 months to an impressive 6 months, while simultaneously reducing maintenance costs by a remarkable 40%.
