Farming applications
Water quality is paramount in farming to ensure optimal animal health and performance. For livestock such as cattle, chickens, sheep, and pigs, both the quantity and quality of water play crucial roles in achieving the best productive outcomes.
Farming operations utilize water from various sources, including water wells, civil water networks, and, to a lesser extent, rivers and superficial sources. Ensuring the purity of water, especially from non-civil sources, is critical in maintaining animal health.
Non-civil water sources often contain high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective way to mitigate these negative effects. Therefore, farm water should undergo advanced treatment to minimize harmful substances, safeguarding the well-being of the animals.

Proshare Revolutionary Team Achievements in Advanced Reverse Osmosis Membrane Technology
Proshare Our brilliant team has ingeniously crafted a next-gen reverse osmosis membrane built upon cutting-edge polymer interface nano-self-assembly technology, triumphing over traditional limitations with two remarkable innovations:
Ultra-Thin Separation Layer: Leveraging polymer interface nanotechnology, we have achieved an extraordinary reduction in the separation layer's thickness to a mere third of the traditional polyamide thin film (previously constrained to 100 nm). This game-changing breakthrough significantly boosts water flux, leading to unparalleled permeability enhancements.
Superior Performance Enhancement: The strategic incorporation of nanoparticles alongside specialized hydrophilic polymers has propelled the membrane's hydrophilicity, anti-fouling capacity, longevity, and oxidation resilience to new heights.
When compared with conventional polyamide reverse osmosis membranes, Proshare's innovation delivers groundbreaking advancements across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping modifications, we create ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This pioneering method transcends the conventional polyamide membranes' limits in both thickness uniformity and material variety.
Amplified Water Flux and Enhanced Energy Efficiency
Through the meticulous refinement of the layer-by-layer self-assembly process, we precisely manage the functional layer thickness, achieving a 3x reduction compared to conventional membranes. This accomplishment results in >3x higher water flux and a remarkable 30% reduction in energy consumption.
Revolutionary Polymer Materials with Unmatched Chemical Stability
Advancing beyond traditional polyamide, our team expertly employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These innovative materials demonstrate outstanding oxidation resistance (withstanding up to 10 ppm chlorine exposure) and exceptional pH tolerance (maintaining stability within a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface (boasting a contact angle <10°), coupled with nanoparticle fortification, reduces organic fouling by 50%, doubling the chemical cleaning intervals from 3 to 6 months, and slashing maintenance costs by a substantial 40%.
