Farming Applications
Water is indispensable for ensuring the optimal health and fitness of farm animals, including cattle, chickens, sheep, and pigs. While the quantity of water is crucial, the water quality is equally vital to achieving the best productive performance from animals.
Farm water can originate from various sources, such as water wells, civil water networks, and occasionally from rivers and other surface sources.
Excluding civil network water, which contains free chlorine, other sources often harbor high levels of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology stands out as the most efficient solution to mitigate these negative effects. Contaminated farm water should undergo technological treatment to reduce harmful substances, ensuring the wellbeing of the animals.

Proshare Team's Revolutionary Leap in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare team has ingeniously crafted a pioneering new generation of reverse osmosis membranes utilizing advanced polymer interface nano-self-assembly technology, surmounting the traditional barriers of reverse osmosis membrane innovation with two remarkable breakthroughs:
Ultra-Thin Separation Layer Mastery: Through the sophisticated application of polymer interface nanotechnology, the team achieved an extraordinary reduction in the separation layer's thickness, rendering it at least thrice thinner than the conventional polyamide thin film (previously confined to 100 nm). This monumental breakthrough amplifies water flux, delivering a significant elevation in permeability.
Superior Enhanced Performance: With the strategic incorporation of nanoparticles and specialized hydrophilic polymers, groundbreaking enhancements have been realized in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films Excellence
Harnessing nano-scale precision control and nano-doping modifications, the creation of ultra-thin, highly ordered separation layers is achieved through polymer interface nanotechnology. This innovative approach transcends the limitations of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Superior Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, the functional layer's thickness is precisely moderated, realizing a remarkable 3x reduction compared to conventional membranes. This advancement leads to >3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Progressing beyond polyamide, the team applies cutting-edge hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These materials boast exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability within a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) coupled with nanoparticle fortification, slashes organic fouling potential by 50%, doubling the chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by an impressive 40%.
