Farming applications
Water plays a critical role in ensuring the health and productivity of animals such as cattle, chickens, sheep, and pigs. Beyond just the quantity, the quality of water is crucial for realizing optimal animal performance and growth.
The water used on farms can be sourced from diverse origins, including water wells, civil water networks, and occasionally from rivers and other superficial sources.
When excluding water from civil networks (which contains free chlorine), other sources often harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective means of mitigating these adverse effects. This technology is essential for treating contaminated farm water, significantly reducing harmful substances to protect animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has ingeniously crafted a pioneering generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology, triumphing over the constraints of conventional reverse osmosis membrane production through two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team achieved a remarkable reduction in the separation layer thickness, making it at least three times thinner than the traditional polyamide thin film, which was previously constrained to 100 nm. This innovation markedly amplifies water flux and profoundly elevates permeability standards.
Enhanced Performance: The strategic incorporation of nanoparticles and unique hydrophilic polymers has resulted in transformative enhancements in membrane hydrophilicity, anti-fouling efficiency, robustness, and oxidation resilience.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs in four vital areas:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control and nano-doping modification facilitates the construction of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This methodology surmounts the hurdles of conventional polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is precisely honed, achieving a threefold reduction compared to traditional membranes. This results in a water flux that is more than three times greater and a remarkable 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond the constraints of polyamide, the team employs state-of-the-art hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids. These materials boast outstanding oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface, with a contact angle of less than 10°, paired with nanoparticle reinforcement, diminishes organic fouling tendency by 50%, extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance expenses by 40%.
