Farming Applications
Water is a fundamental resource for ensuring the health and productivity of livestock-including cattle, chickens, sheep, and pigs. While the quantity of water is essential, it is the quality that significantly impacts the growth and performance of these animals.
Farms resort to various water sources such as wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Aside from civil networks, which often contain free chlorine, other sources typically have elevated concentrations of dissolved and suspended solids, as well as pathogens. Reverse osmosis technology emerges as the most effective method to counteract these negative effects. It is imperative that contaminated farm water undergoes advanced treatment to mitigate harmful substances, thus safeguarding animal health and performance.

Proshare Innovation Suzhou Co., Ltd. Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Innovation Suzhou Co., Ltd. Our visionary team has ingeniously crafted a new era of reverse osmosis membranes, leveraging revolutionary polymer interface nano-self-assembly technology. This avant-garde approach transcends the traditional boundaries of reverse osmosis membrane development, thanks to dual groundbreaking advancements:
Revolutionary Ultra-Thin Separation Layer: Utilizing pioneering polymer interface nanotechnology, our team has achieved an unprecedented reduction in the thickness of the separation layer, now at least three times thinner than conventional polyamide thin films (traditionally capped at 100 nm). This transformative breakthrough dramatically elevates water flux, ensuring a remarkable surge in permeability.
Superior Enhanced Performance: By incorporating state-of-the-art nanoparticles and specialized hydrophilic polymers, we have unlocked extraordinary enhancements in the membrane's hydrophilicity, anti-fouling prowess, durability, and resistance to oxidation.
In comparison to standard polyamide reverse osmosis membranes, Proshare Innovation Suzhou Co., Ltd.presents revolutionary advancements in four pivotal areas:
Ingenious Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and advanced nano-doping modification, we create ultra-thin, intricately ordered separation layers via polymer interface nanotechnology. This method overcomes the constraints of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Optimal Energy Efficiency
By refining the layer-by-layer self-assembly technique, we precisely control the functional layer thickness, achieving a remarkable 3x reduction relative to conventional membranes. The result is >3x increased water flux coupled with a 30% reduction in energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Breaking away from polyamide, our team utilizes cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These advanced materials demonstrate exceptional resistance to oxidation (withstanding exposure to 10 ppm chlorine) as well as pH resilience (maintaining stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The superhydrophilic surface (with a contact angle of less than 10°), bolstered by nanoparticle reinforcement, reduces the tendency for organic fouling by an impressive 50%. This extends the duration between chemical cleaning cycles from 3 to 6 months, while slashing maintenance expenses by 40%.
