Farming applications
Water is essential to ensure the well-being of animals (e.g. cattle, chickens, sheep, pigs) and to achieve optimal animal performance. However, the growth and productivity of these animals are influenced not only by the quantity but also by the quality of the water.
Water for farming can originate from multiple sources, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Excluding water from civil networks (which contains free chlorine), other sources often have high concentrations of dissolved and suspended solids and pathogens. Therefore, reverse osmosis technology has proven to be the most efficient method to mitigate their negative effects. Contaminated water used on farms must undergo technological treatment to reduce substances harmful to animals.

Proshare Pioneering Breakthroughs in Next-Gen Reverse Osmosis Membranes
Proshare Our innovative team has crafted a cutting-edge generation of reverse osmosis membranes leveraging state-of-the-art polymer interface nano-self-assembly technology. This breakthrough triumphantly surpasses the conventional constraints of reverse osmosis membrane development through two monumental strides:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, the team has achieved an extraordinary reduction in the separation layer's thickness to a mere fraction-at least three times thinner than the conventional polyamide thin film. Previously capped at 100 nm, this revolutionary development dramatically enhances water flux, resulting in a remarkable boost in permeability.
Exemplary Performance Enhancement: By incorporating nanoparticles alongside specialized hydrophilic polymers, we have reached a new pinnacle in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, marking a significant leap forward.
When set against the traditional polyamide reverse osmosis membranes, Proshare's innovations reveal groundbreaking advancements in four pivotal dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we have mastered the creation of ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology, effectively transcending the traditional polyamide membrane's limitations in thickness uniformity and material diversity.
Enhanced Water Flux Coupled with Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, we have achieved precise control over the functional layer's thickness, slashing it by a factor of three compared to traditional membranes. This mastery culminates in >3x the water flux combined with a 30% reduction in energy consumption.
Revolutionary Polymer Materials with Exceptional Chemical Stability
Advancing beyond polyamide constraints, our team deploys cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials offer unmatched oxidation resistance (withstanding exposure to 10 ppm chlorine) and superior pH tolerance (maintaining stability within a 1-12 pH range).
Sophisticated Anti-Fouling Surface Engineering
Our superhydrophilic surface, characterized by a contact angle of less than 10°, is fortified with nanoparticle reinforcement, which remarkably reduces the propensity for organic fouling by 50%, extends chemical cleaning cycles from 3 months to a notable 6 months, and slashes maintenance costs by 40%
