Hospitality/Seawater and Brackish Water Desalination Applications
Proshare brings its extensive expertise in desalination technology to water desalination solutions for the hospitality industry, specifically hotels and touristic resorts. Freshwater provision is crucial for these infrastructures, and our R.O. sea or brackish water desalination systems offer an effective solution to meet the burgeoning demands of these rapidly growing areas.
Farming applications
Water quality and availability are critical for ensuring the health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. Notably, both water amount and quality significantly impact the optimal growth and performance of livestock.
Farm water can be sourced from a variety of origins, including water wells, civil water networks, and, to a lesser degree, rivers and other surface sources, each with its distinct challenges and benefits.
Except for water from civil networks (which contains free chlorine), other sources often present high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the premier solution to mitigate these adverse effects, ensuring that farm water undergoes essential technological treatment to eliminate harmful substances.

Proshare: Pioneers in Innovation Revolutionary Breakthroughs in Reverse Osmosis Membrane Technology by Our Team
Proshare: Leading the Way in Water Filtration Our team has boldly developed a cutting-edge generation of reverse osmosis membranes, leveraging the power of polymer interface nano-self-assembly technology. This significant leap forward has conquered traditional barriers in membrane development through two pivotal advancements:
Ultra-Thin Separation Layer Mastery: Harnessing the potential of polymer interface nanotechnology, our team has dramatically reduced the thickness of the separation layer to an astonishing new level-three times thinner than traditional polyamide thin films (formerly limited to 100 nm). This groundbreaking progression substantially boosts water flux, culminating in remarkable permeability improvements.
Enhanced Performance Redefined: By integrating nanoparticles and specialized hydrophilic polymers, we have pioneered advancements in hydrophilicity, dramatically boosting anti-fouling capabilities, durability, and oxidation resistance of the membranes.
Surpassing Traditional Polyamide Reverse Osmosis Membranes, Proshare's innovation showcases remarkable strides in four core areas:
Self-Assembled Nanocomposite Films Excellence
Through precision at the nano-scale and nano-doping modification, we craft ultra-thin, highly ordered separation layers with polymer interface nanotechnology. This innovative method resolves the constraints of conventional polyamide membranes regarding thickness uniformity and material diversity.
Unprecedented Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, we achieve precise functional layer thickness control, reducing it by 3x compared to traditional membranes. This innovation results in water flux exceeding 3x and energy consumption reduced by 30%.
Innovative Polymer Materials with Exceptional Chemical Stability
Surpassing polyamide, we employ advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials offer unmatched oxidation resistance (withstanding chlorine exposure up to 10 ppm) and pH tolerance (remains stable across a pH range of 1-12).
Pioneering Anti-Fouling Surface Engineering
With a superhydrophilic surface (contact angle <10°) reinforced with nanoparticles, our membranes reduce organic fouling by 50%, doubling chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by 40%.
Our prestigious certifications include the Health & Safety Management System Certificate, the Environmental Management System Certificate, and the ISO9001 Quality System Certificate. These achievements underscore our commitment to excellence and sustainability.
