In environments where impeccably pure water is a non-negotiable requirement for diverse industrial processes, our expertise shines through. Our pioneering endeavors in wastewater treatment, resource recycling, and sustainable reuse of water have solidified our position as industry leaders.
We actively operate in substantial industry sectors such as petrochemical, mining, lithium extraction from salt lake, lithium iron phosphate & lithium battery recycling, semiconductor, sea water desalination, reclaimed water management, leachate processing, synthetic biology, copper foil production, pharmaceuticals, and the power sector.
Our solutions are equally transformative across other sectors including steam boiler feeding, food & beverages (covering everything from mineral water bottling to soft drinks and juices), painting lines, dairy production, ice cream manufacturing, laundries, hospitals, textile, mechanical industries, and steel companies, among others.
Hospitality/Seawater and Brackish Water Desalination Applications
Drawing from Proshare's extensive expertise in desalination technology, we have extended our prowess to water desalination solutions for civil applications, specifically in hotels and tourist resorts. The provision of fresh water is crucial for such infrastructures, and our Reverse Osmosis (R.O.) solutions for seawater or brackish water desalination offer a reliable alternative. These solutions are designed to meet the expanding capacities and increasing water demands of rapidly evolving tourist regions.
Farming applications
Water holds paramount importance in ensuring the health and productivity of farm animals, be it cattle, chickens, sheep, or pigs. Optimal animal performance hinges not only on the quantity but significantly on the quality of water. Proshare's solutions cater to this pivotal aspect for superior livestock results.
Farm water can originate from various sources, including water wells, municipal water networks, and, to a lesser degree, rivers and other surface sources. Our solutions are adaptable to the diverse nature of these sources.
While municipal water networks are often treated with free chlorine, other sources are typically laden with high concentrations of dissolved solids and pathogens. Reverse osmosis technology emerges as the most effective solution to mitigate these contaminants. By subjecting farm water to advanced technological treatment, we ensure the reduction of harmful substances, safeguarding animal health.
Municipal and Civil use
We deliver forward-thinking and adaptable solutions to clients for the efficient and eco-friendly treatment of wastewater and effluents. Our comprehensive suite of patented technologies, bolstered by a team of national-level experts and collaborations with leading scientific research institutions, offers unmatched reliability for municipalities facing stringent health and environmental regulations.

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.

Proshare Pioneering Breakthroughs in Advanced Reverse Osmosis Membrane Technology
Proshare Our expert team has brilliantly innovated a cutting-edge generation of reverse osmosis membranes, leveraging the revolutionary polymer interface nano-self-assembly technology. This breakthrough triumphantly overcomes the traditional development barriers of reverse osmosis membranes with two transformative advancements:
Revolutionary Ultra-Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, we've achieved an extraordinary reduction in the separation layer's thickness, achieving a remarkable threefold decrease compared to the conventional polyamide thin film, which was previously constrained to 100 nm. This innovation powerfully boosts water flux, ensuring a dramatic increase in permeability.
Superior Enhanced Performance: The strategic integration of nanoparticles and tailored hydrophilic polymers has spearheaded revolutionary advancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance of our membranes.
In comparison with traditional polyamide reverse osmosis membranes, Proshare's ground-breaking innovation showcases significant progress across four pivotal aspects:
Self-Assembled Nanocomposite Films of Excellence
With nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This pioneering approach transcends the conventional constraints of polyamide membranes, offering unmatched uniformity in thickness and material diversity.
Enhanced Water Flux and Outstanding Energy Efficiency
By refining the layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, achieving a remarkable threefold reduction when compared to traditional membranes. This innovation leads to more than a threefold increase in water flux and an impressive 30% reduction in energy consumption.
Advanced Polymer Materials with Exceptional Chemical Stability
Transitioning beyond polyamide, we employ state-of-the-art hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These cutting-edge materials exhibit remarkable resistance to oxidation (withstanding exposure to 10 ppm chlorine) as well as superior pH tolerance (maintaining stability within a 1-12 pH range).
Innovative Anti-Fouling Surface Engineering
Our superhydrophilic surface, characterized by a contact angle of less than 10°, combined with nanoparticle reinforcement, significantly reduces organic fouling propensity by an impressive 50%. This effectively extends the chemical cleaning cycles from three to six months and reduces maintenance costs by a remarkable 40%.
