Industry Applications
Proshare Proshare has meticulously cultivated a wealth of expertise by delivering specialized technical solutions to the industrial sector. We cater to industries where absolutely pure water is paramount, particularly in critical processes such as wastewater treatment, resource recycling, and reuse.
Our engagement spans across diverse industry sectors including petrochemical, mining, lithium extraction from salt lakes, lithium iron phosphate & lithium battery recycling, semiconductor, seawater desalination, reclaimed water systems, leachate treatment, synthetic biology, copper foil production, pharmaceutical industries, and power generation.
Our expertise extends to a multitude of sectors such as steam boiler feeding, food and beverages (mineral water bottling, soft drinks, juices), painting lines, dairies, ice cream production, laundries, hospitals, textile and mechanical industries, and steel manufacturing, among others.
Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology is also harnessed in the civil domain for hotels and touristic resorts. The provision of a fresh water supply is vital for such infrastructures. Reverse Osmosis (R.O.) technology for seawater or brackish water desalination offers an alternative solution adept at meeting the growing water demands of rapidly expanding touristic areas.
Farming applications
Water quality is crucial in farming to ensure optimal health and productivity of animals such as cattle, chickens, sheep, and pigs. Both the quality and quantity of water play significant roles in achieving desired growth and performance.
Farms can source their water from various origins, including water wells, civil water networks, and to a lesser extent, rivers and other superficial sources.
While water from civil networks often contains free chlorine, other sources generally have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most efficient method to mitigate these adverse effects, ensuring that contaminated farm water is treated to remove harmful substances affecting animal health.
Municipal and Civil use
We offer cutting-edge, scalable solutions for the efficient and sustainable treatment of wastewater and effluents. Our expansive portfolio of patented technologies, alongside national-level experts and partnerships with scientific research institutions, guarantee compliance with strict health and environmental standards, offering municipalities peace of mind.

Proshare Revolutionary Triumph in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare team has brilliantly pioneered a state-of-the-art generation of reverse osmosis membranes, leveraging the groundbreaking polymer interface nano-self-assembly technology to shatter the constraints of traditional reverse osmosis membrane innovation through two pivotal advancements:
Ultra-Thin Separation Layer: By harnessing the remarkable capabilities of polymer interface nanotechnology, our team has impressively minimized the thickness of the separation layer, achieving a remarkable reduction to at least three times thinner than the conventional polyamide thin film (historically capped at 100 nm). This unprecedented breakthrough dramatically boosts water flux, resulting in a remarkable leap in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles and unique hydrophilic polymers has propelled the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance to groundbreaking new heights.
In stark contrast to conventional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases remarkable breakthroughs in four essential domains:
Self-Assembled Nanocomposite Films
The seamless integration of nano-scale precision control and nano-doping modification empowers the creation of ultra-thin, meticulously ordered separation layers through the use of polymer interface nanotechnology. This innovative approach transcends the constraints of traditional polyamide membranes in regards to thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, the thickness of the functional layer is precisely regulated, achieving a significant 3x reduction compared to traditional membranes. This transformative advancement results in >3x higher water flux and 30% lower energy consumption.
Revolutionary Polymer Materials with Unrivaled Chemical Stability
Moving beyond the traditional polyamide confines, our team employs advanced hydrophilic polymers (such as modified polysulfones) along with ceramic-organic hybrids. These extraordinary materials exhibit unparalleled oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface (with a contact angle of <10°) alongside nanoparticle reinforcement dramatically curtails the propensity for organic fouling by an impressive 50%, extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by 40%.
