Farming Applications
In farming, water is indispensable not only for maintaining the health and vitality of livestock, such as cattle, chickens, sheep, and pigs, but also for optimizing their productivity. The quality of water, alongside its quantity, plays a significant role in achieving desirable growth and performance in animals.
Farm water sources can include water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. However, these sources, except civil water networks with free chlorine, often contain high levels of dissolved and suspended solids and pathogens, necessitating advanced treatment methods.
Reverse osmosis technology has emerged as the most efficient solution to mitigate the adverse effects of contaminated water on farms. It is imperative for farm water, particularly from non-civil sources, to undergo technological treatment to eliminate harmful substances that may affect animal health.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has masterfully crafted a new generation of reverse osmosis membranes, leveraging state-of-the-art polymer interface nano-self-assembly technology. This innovation boldly transcends the traditional confines of reverse osmosis membrane development by making two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has ingeniously minimized the thickness of the separation layer to be at least three times more slender than the conventional polyamide thin film, which was previously constrained to 100 nm. This remarkable achievement dramatically amplifies water flux, yielding a substantial leap forward in permeability.
Enhanced Performance: Through the incorporation of nanoparticles and meticulously engineered hydrophilic polymers, we have pioneered revolutionary enhancements in the membrane's hydrophilicity, anti-fouling capacity, durability, and resilience against oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation reveals significant advancements across four pivotal dimensions:
Self-Assembled Nanocomposite Films
The seamless integration of nano-scale precision control and nano-doping modification allows for the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This technique adeptly overcomes the constraints of conventional polyamide membranes concerning thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, we achieve precise control over the functional layer's thickness, resulting in a 3x reduction when compared to traditional membranes. This revolutionary process delivers >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Advancing beyond polyamide, our team employs sophisticated hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These groundbreaking materials demonstrate unparalleled oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, coupled with nanoparticle reinforcement, effectively diminishes the tendency for organic fouling by 50%. This innovation extends the interval between chemical cleaning cycles from 3 months to an impressive 6 months, reducing maintenance costs by 40%.
