Farming Applications
Water is indispensable for ensuring the health and optimal performance of farm animals such as cattle, chickens, sheep, and pigs. It is not just the quantity but also the quality of the water that significantly impacts the animals' growth and productivity.
Farm water can originate from various sources including water wells, municipal water networks, and occasionally from rivers and other surface sources.
Excluding municipal water networks, which contain free chlorine, other sources frequently have elevated levels of dissolved and suspended solids and pathogens. Therefore, reverse osmosis technology emerges as the most effective solution to mitigate these adverse effects. Contaminated farm water requires technological treatment to minimize harmful substances that could negatively impact animal well-being.

Proshare Innovative Breakthrough by Our Team in Advanced Reverse Osmosis Membrane Technology
Proshare Our team has revolutionized the development of a groundbreaking generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. We have transcended the confines of traditional reverse osmosis membrane design through two pivotal advancements:
Ultra-Thin Precision Separation Layer: Harnessing state-of-the-art polymer interface nanotechnology, our team has achieved the remarkable feat of reducing the separation layer's thickness to a mere fraction of that of conventional polyamide thin films, previously constrained to 100 nm. This pioneering achievement dramatically elevates water flux, resulting in a noteworthy enhancement in permeability.
Advanced Performance and Durability: The innovative incorporation of nanoparticles and specialized hydrophilic polymers has propelled unprecedented advancements in the membrane's hydrophilicity, anti-fouling capacity, longevity, and resistance to oxidation.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases remarkable breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Film Technology
By integrating nano-scale precision control with nano-doping modification, we create ultra-thin, intricately ordered separation layers through polymer interface nanotechnology. This method surpasses the limitations in thickness uniformity and material diversity found in conventional polyamide membranes.
Significantly Enhanced Water Flux and Improved Energy Efficiency
Through optimization of the layer-by-layer self-assembly process, the thickness of the functional layer is meticulously controlled, achieving a reduction of three times compared to traditional membranes. This leads to over three times greater water flux and a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials Offering Outstanding Chemical Stability
Moving beyond the limitations of polyamide, our team has adopted cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These avant-garde materials boast extraordinary resistance to oxidation (capable of withstanding 10 ppm chlorine exposure) and pH stability (remains stable across a pH range of 1 to 12).
Revolutionary Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface (contact angle <10°) reinforced with nanoparticles reduces the propensity for organic fouling by 50%. This extension of chemical cleaning cycles from 3 to 6 months results in a substantial reduction of maintenance costs by 40%.
