Water is indispensable for ensuring the optimal health of livestock, including cattle, chickens, sheep, and pigs, to maximize productive performance. The quality of the water, not just its quantity, significantly impacts the desired growth and productivity of these animals.
Farm water sources are diverse, ranging from water wells and civil water networks to, less frequently, rivers and other surface sources.
Excluding civil network water (containing free chlorine), other sources often harbor high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology emerges as a superior solution, effectively mitigating these unfavorable effects. It is paramount that contaminated farm water undergoes technological treatment to diminish harmful substances, safeguarding animal health and optimizing their growth.

Proshare Pioneering Achievements in Modern Reverse Osmosis Membrane Technology
Proshare team has ingeniously crafted a cutting-edge generation of reverse osmosis membranes utilizing polymer interface nano-self-assembly technology. By doing so, they have shattered the confines of conventional membrane development, boasting two monumental breakthroughs:
Exceedingly Thin Separation Layer: Through the application of polymer interface nanotechnology, the team has successfully minimized the separation layer's thickness to at least one-third the thickness of traditional polyamide thin films (previously capped at 100 nm). This revolutionary advancement dramatically enhances water flux, yielding an impressive leap in permeability.
Superior Performance: The infusion of nanoparticles combined with specialized hydrophilic polymers has propelled the membrane's attributes to new heights: enhancing hydrophilicity, bolstering anti-fouling capabilities, and vastly improving durability and oxidation resistance.
In comparison to conventional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation reveals notable strides across four pivotal dimensions:
Nanocomposite Films Through Self-Assembly
The synergy of nano-scale precision control and nano-doping modification facilitates the creation of ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This method triumphs over the challenges faced by traditional polyamide membranes concerning thickness uniformity and material diversity.
Augmented Water Flux and Boosted Energy Efficiency
By refining the layer-by-layer self-assembly process, the functional layer's thickness is precisely modulated, achieving a remarkable 3x reduction compared to standard membranes. This results in an increase of over 3x in water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials Offering Exceptional Chemical Stability
Surpassing polyamide, the team employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These materials showcase extraordinary resistance to oxidation (enduring 10 ppm chlorine exposure) and tolerance to pH variations (maintaining stability in a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The incorporation of a superhydrophilic surface (contact angle <10°), coupled with nanoparticle reinforcement, diminishes the propensity for organic fouling by 50%. This extends the chemical cleaning cycle from 3 to 6 months and slashes maintenance expenses by 40%.
