Farming Applications
Water is a critical component for ensuring the health and optimal performance of farm animals, such as cattle, chickens, sheep, and pigs. The quality of water, not just its availability, plays a pivotal role in achieving the desired growth and productivity of these animals.
Water used on farms originates from various sources, including water wells, civil water networks, and, less commonly, rivers and other surface sources. Ensuring the right water quality involves understanding these diverse origins.
Except for water from civil networks, which typically contains free chlorine, other sources often harbor high levels of dissolved solids and pathogens. Hence, reverse osmosis technology stands out as the most effective method to mitigate these adverse effects. Contaminated farm water should be technologically refined to minimize harmful substances, safeguarding animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has revolutionized the field with a pioneering new generation of reverse osmosis membranes, crafted through cutting-edge polymer interface nano-self-assembly technology. This innovation transcends the boundaries of traditional reverse osmosis membrane development with two monumental advances:
Ultra-Thin Separation Layer: Leveraging state-of-the-art polymer interface nanotechnology, our team has achieved a remarkable reduction in the separation layer thickness, now boasting a layer that's at least three times thinner than the conventional polyamide film (traditionally capped at 100 nm). This significant advancement dramatically boosts water flux, offering a notable surge in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles alongside bespoke hydrophilic polymers has culminated in a series of groundbreaking advancements. These include superior hydrophilicity, enhanced anti-fouling capabilities, increased durability, and robust oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers via advanced polymer interface nanotechnology. This novel approach triumphs over the conventional polyamide membranes, offering superior thickness uniformity and diverse material applications.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, we meticulously control the functional layer's thickness, achieving an impressive 3x reduction compared to traditional membranes. This innovation culminates in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the bounds of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These cutting-edge materials are characterized by their exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a 1-12 pH spectrum).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, markedly diminishes the tendency for organic fouling by 50%. This advancement extends chemical cleaning cycles from 3 to 6 months, resulting in a remarkable 40% reduction in maintenance costs.
