Farming applications

Water quality is crucial to ensure the optimal health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. Not only does the quantity matter, but the quality of water is a key factor in facilitating the desired growth and performance of these animals.
Farm water can originate from diverse sources, including water wells, civil water networks, and occasionally rivers or other surface sources, each requiring thoughtful management.
Water not sourced from civil networks (which contain free chlorine) often holds high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology emerges as the most effective solution to mitigate these impurities, ensuring the treated water meets the health needs of farm animals by reducing harmful substances.

Proshare - Pioneers in Innovation Our Team's Breakthrough: Pioneering the Next-Generation Reverse Osmosis Membrane Technology
Proshare - Innovating for Tomorrow Our visionary team has ingeniously pioneered a revolutionary new generation of reverse osmosis membranes, crafted through cutting-edge polymer interface nano-self-assembly technology. This transformative approach triumphantly surpasses the confines of traditional membrane development through two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Through the mastery of polymer interface nanotechnology, our team has remarkably diminished the separation layer's thickness to a staggering threefold reduction compared to conventional polyamide thin films (traditionally constrained to 100 nm). This monumental breakthrough substantially elevates water flux, culminating in a remarkable enhancement in permeability.
Unmatched Enhanced Performance: With the strategic integration of nanoparticles and cutting-edge hydrophilic polymers, we have ushered in groundbreaking advancements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's breakthrough innovation shines in four crucial dimensions:
Self-Assembled Nanocomposite Films
By seamlessly integrating nano-scale precision control with nano-doping modification, we create ultra-thin, impeccably ordered separation layers using state-of-the-art polymer interface nanotechnology. This pioneering method addresses the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Superior Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we achieve precise control over functional layer thickness, leading to a 3x reduction compared to traditional membranes. This innovation delivers an astonishing >3x increase in water flux and a 30% reduction in energy consumption.
Revolutionary Polymer Materials with Exceptional Chemical Stability
Breaking free from the constraints of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids. These materials exhibit outstanding oxidation resistance capable of withstanding exposure to 10 ppm chlorine and unparalleled pH tolerance maintaining stability across a wide pH range of 1-12.
Sophisticated Anti-Fouling Surface Engineering
Our innovative superhydrophilic surface (with a contact angle of less than 10°) fortified by nanoparticle reinforcement, dramatically reduces the propensity for organic fouling by 50%. This advancement extends the duration between chemical cleaning cycles from 3 to 6 months and slashes maintenance costs by 40%.
