Farming Applications

Water is crucial to ensuring animal health and maximizing performance in livestock such as cattle, chickens, sheep, and pigs. However, it is not merely the quantity but also the purity of the water that critically impacts the growth and productivity of these animals.
Farm water sources are diverse, ranging from wells and civil water networks to, albeit less commonly, rivers and surface water sources. Each source brings variable qualities requiring careful management.
Excluding civil network water (which contains free chlorine), other sources often possess high levels of dissolved solids and pathogens. Reverse osmosis technology emerges as the most efficient solution to mitigate these adverse effects. Contaminated farm water must be technologically treated to decrease harmful substances, safeguarding animal health and performance.

Our Advantages

Proshare Trailblazing Innovations in Advanced Reverse Osmosis Membrane Technology
Proshare has pioneered an advanced generation of reverse osmosis membranes utilizing polymer interface nano-self-assembly technology, transcending the boundaries of traditional membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team has successfully achieved a dramatic reduction in the thickness of the separation layer, crafting it to be at least three times thinner than the conventional polyamide thin film (previously bound to a limit of 100 nm). This innovation dramatically boosts water flux, marking a significant enhancement in permeability.
Enhanced Performance: By infusing the membrane with nanoparticles and specialized hydrophilic polymers, the team has unlocked groundbreaking enhancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
When placed against traditional polyamide reverse osmosis membranes, Proshare's remarkable innovation showcases advancements in four crucial domains:
Self-Assembled Nanocomposite Films
The amalgamation of nano-scale precision control and nano-doping modification facilitates the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This strategy surmounts the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, the functional layer thickness is precisely controlled, achieving a remarkable 3x reduction compared to traditional membranes. This advancement yields over 3x higher water flux and 30% reduced energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, the team leverages advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials exhibit outstanding oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
The superhydrophilic surface (with a contact angle of less than 10°) enhanced by nanoparticle reinforcement notably reduces organic fouling propensity by 50%, extending the intervals between chemical cleaning cycles from 3 months to 6 months, and reducing maintenance costs by 40%.
