Farming applications
Water is a crucial element in ensuring the health and optimum productivity of farm animals such as cattle, chickens, sheep, and pigs. However, the quality of water is as vital as its quantity, playing a significant role in the growth and productivity of these animals.
The water utilized on farms can originate from a variety of sources, such as water wells, civil water networks, and occasionally, rivers and other surface sources, each impacting the quality of water differently.
Except for water from civil networks, typically containing free chlorine, other sources tend to have elevated levels of dissolved solids, suspended solids, and pathogens. Reverse osmosis technology has emerged as the most efficient method to mitigate these adverse effects. To protect animals from harmful substances, water used on farms must undergo technological treatment, ensuring suitability and safety.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The team at Proshare has ingeniously crafted a revolutionary generation of reverse osmosis membranes, leveraging advanced polymer interface nano-self-assembly technology. This cutting-edge development triumphantly addresses the constraints of conventional reverse osmosis membranes through two remarkable innovations:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, the team has achieved a pioneering reduction in separation layer thickness, making it at least threefold thinner than traditional polyamide thin films, which were previously confined to a 100 nm limitation. This phenomenal breakthrough dramatically amplifies water flux, attaining significant enhancements in permeability.
Enhanced Performance: The infusion of nanoparticles and exclusive hydrophilic polymers has catalyzed transformative progress in the membrane's hydrophilicity, anti-fouling proficiency, longevity, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation heralds breakthroughs in four pivotal dimensions:
Self-Assembled Nanocomposite Films
By adeptly merging nano-scale precision control with nano-doping modification, we produce ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This method triumphantly overcomes the traditional polyamide membranes' shortcomings in thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is rigorously controlled, achieving a remarkable 3x reduction in comparison to traditional membranes. This results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Departing from the constraints of polyamide, the team employs cutting-edge hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These avant-garde materials showcase unparalleled oxidation resistance (capable of withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, significantly diminishes organic fouling potential by 50%. This advancement extends the chemical cleaning cycle from 3 to 6 months, while notably slashing maintenance costs by 40%
