Industry Applications
Proshare Proshare has garnered invaluable expertise by delivering cutting-edge technical solutions specifically tailored for the industrial sector. This is crucial where impeccably pure water is a non-negotiable requisite for diverse industrial processes, including waste water treatment, reuse, and resource recycling.
Our core engagement spans across pivotal industry sectors such as petrochemical, mining, and innovative lithium extraction from salt lakes. We play a significant role in lithium iron phosphate and battery recycling, semiconductor advancements, seawater desalination, reclaimed water, leachate, synthetic biology, copper foil production, pharmaceuticals, and power industries.
Moreover, our expertise extends to critical applications such as steam boilers feeding, the food and beverage sector (including mineral water bottling, soft drinks, and juices), painting lines, dairies, ice creams, laundries, hospitals, textile, mechanical industries, and steel companies, among others.
Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology is equally applied to the realm of water desalination for civil infrastructures such as hotels and touristic resorts. Ensuring a fresh water supply is paramount for these entities. Our R.O. sea water or brackish water desalination provides a robust alternative solution, satisfying the escalating water demands of rapidly expanding touristic areas.
Farming applications
Water quality and availability are critical for ensuring optimal health and productivity in farm animals such as cattle, chickens, sheep, and pigs. While quantity matters, the water's quality significantly influences the growth and performance of these animals.
Farms may source water from various origins, including water wells, civil water networks, and to a lesser extent, rivers and surface sources. These diverse sources each present unique challenges and advantages.
Except for civil network water (with free chlorine), other sources typically harbor high concentrations of dissolved/suspended solids and pathogens. Reverse osmosis technology stands as the most effective method to mitigate these adverse effects, ensuring contaminated farm water undergoes necessary technological treatments to eliminate harmful substances.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare With a pioneering spirit, the Proshare team has masterfully crafted a revolutionary new generation of reverse osmosis membranes. Using cutting-edge polymer interface nano-self-assembly technology, they have shattered the boundaries of traditional membrane development, achieving unparalleled success through two transformative advancements:
Ultra-Thin Separation Layer: Leveraging the power of polymer interface nanotechnology, our team has remarkably minimized the separation layer thickness to a groundbreaking threefold reduction compared to the conventional polyamide thin film, previously constrained to 100 nm. This monumental stride amplifies water flux, culminating in a remarkable enhancement of permeability.
Enhanced Performance: Through the strategic introduction of nanoparticles and advanced hydrophilic polymers, we have propelled the membrane's performance to extraordinary heights, boosting hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation excels in four pivotal aspects:
Self-Assembled Nanocomposite Films
By synergizing nano-scale precision control with nano-doping modification, we craft ultra-thin, meticulously ordered separation layers through the marvel of polymer interface nanotechnology. This innovation triumphs over conventional polyamide membrane constraints in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous layer-by-layer self-assembly optimization, we achieve precision-controlled functional layer thickness that outstrips traditional membranes with a remarkable 3x reduction, resulting in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Transcending polyamide, we harness the potential of advanced hydrophilic polymers (such as modified polysulfones) and innovative ceramic-organic hybrids. These materials showcase exceptional oxidation resistance and can endure 10 ppm chlorine exposure, while pH tolerance remains robust across a 1-12 pH range.
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with an impressively low contact angle of <10°, paired with nanoparticle reinforcement, diminishes organic fouling by 50%.
