We are committed to providing water solutions that maximize animal performance and welfare.
Farm water may originate from various sources, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources. Our expertise ensures that regardless of the source, water quality is maintained at the highest standard.
With the exclusion of civil network water containing free chlorine, other sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most efficient in mitigating these adverse effects. To protect farm animals, contaminated water must undergo advanced technological treatment to minimize harmful substances, safeguarding their health and enhancing farm productivity.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The innovative Proshare team has pioneered a cutting-edge generation of reverse osmosis membranes, skillfully harnessing polymer interface nano-self-assembly technology. This remarkable advancement surmounts the traditional challenges faced in reverse osmosis membrane development through two revolutionary breakthroughs:
Ultra-Thin Separation Layer: Utilizing the advanced polymer interface nanotechnology, our team has triumphantly reduced the separation layer's thickness to an astonishingly slim profile, at least three times thinner than the conventional polyamide thin film, which was previously constrained to 100 nm. This monumental progress significantly elevates water flux, thereby achieving a dramatic enhancement in permeability.
Enhanced Performance: Through the innovative integration of nanoparticles and specialized hydrophilic polymers, we have realized groundbreaking improvements in the membrane's hydrophilicity, anti-fouling prowess, durability, and robust oxidation resistance.
In comparison with the traditional polyamide reverse osmosis membranes, Proshare's groundbreaking advancements are evident in four pivotal areas:
Self-Assembled Nanocomposite Films
By seamlessly integrating nano-scale precision control with nano-doping modification, we craft ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This innovative method transcends the conventional constraints of polyamide membranes in both thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we achieve precise control over the functional layer's thickness, resulting in a remarkable 3x reduction compared to traditional membranes. This achievement yields >3x higher water flux while driving energy consumption down by 30%.
Novel Polymer Materials with Superior Chemical Stability
Breaking free from conventional polyamide, our team employs state-of-the-art hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials showcase extraordinary resistance to oxidation (withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
With an ultra-hydrophilic surface (contact angle <10°) enhanced by nanoparticle reinforcement, we significantly mitigate organic fouling by 50%, extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by 40%.
