Farming applications
Water is indispensable in ensuring the health and optimal performance of farm animals like cattle, chickens, sheep, and pigs. However, it's not just the quantity but the quality of water that plays a crucial role in promoting desired growth and productivity.
Water sources for farms may originate from wells, civil water networks, and occasionally rivers or other surface sources. It's essential to manage these sources effectively to ensure optimal water quality.
Excluding civil network water (which contains 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 means of mitigating these adverse effects. By treating contaminated farm water, we significantly reduce harmful substances, ensuring the health and productivity of farm animals.

Proshare Pioneering Breakthroughs in Cutting-edge Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously developed a groundbreaking new generation of reverse osmosis membranes, utilizing polymer interface nano-self-assembly technology. This innovation triumphs over the constraints of traditional reverse membrane development through two game-changing advancements:
Revolutionary Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, our team has successfully achieved a remarkable reduction in the separation layer thickness, making it at least three times thinner than the conventional polyamide thin film, which was previously capped at 100 nm. This pivotal breakthrough dramatically boosts water flux, culminating in a significant enhancement of permeability.
Superior Enhanced Performance: The advent of nanoparticles combined with specialized hydrophilic polymers has unleashed revolutionary advancements in membrane hydrophilicity. This innovation enhances anti-fouling capability, boosts durability, and strengthens oxidation resistance remarkably.
In comparison to the traditional polyamide reverse osmosis membranes, Proshare's innovation marks transformative breakthroughs in these four essential dimensions:
Self-Assembled Nanocomposite Films with Precision
Through the fusion of nano-scale precision control and innovative nano-doping modification, we craft ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This cutting-edge approach overcomes conventional polyamide membrane limitations regarding thickness uniformity and material diversity.
Exceptional Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we accurately control functional layer thickness, achieving an impressive 3x reduction compared to traditional membranes. This breakthrough yields an impressive >3x higher water flux and a significant 30% reduction in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
Venture beyond polyamide with our use of cutting-edge hydrophilic polymers, like modified polysulfones, along with ceramic-organic hybrids. These advanced materials showcase incredible oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and impressive pH tolerance (remaining stable across a pH range of 1-12).
Sophisticated Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (boasting a contact angle <10°) coupled with robust nanoparticle reinforcement dramatically reduces the propensity for organic fouling by 50%. This advancement extends the chemical cleaning cycle from 3 to an impressive 6 months, simultaneously slashing maintenance costs by 40%.
