Farming applications

Water is an indispensable element in ensuring the health and productivity of animals such as cattle, chickens, sheep, and pigs, ensuring they reach optimal performance levels. However, both the quantity and quality of water play pivotal roles in fostering the desired growth of these animals.
The farm's water supply may originate from various sources, including water wells, municipal water networks, and occasionally from rivers and other surface sources.
Excluding municipal networks (which contain free chlorine), other sources often bear high levels of dissolved solids, suspended particles, and pathogens. Here, reverse osmosis technology shines as the most effective method to mitigate these detrimental effects, ensuring that the farm's water undergoes comprehensive technological treatment to minimize substances harmful to animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Traditionally, the utilization of desalination membranes in high-end international cruise ships has been monopolized by a select few global brands.

Our Advantages

Proshare Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously crafted a next-generation reverse osmosis membrane, utilizing revolutionary polymer interface nano-self-assembly technology. This outstanding feat overcomes the traditional limitations of reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: With the innovative application of polymer interface nanotechnology, our team has achieved an extraordinary reduction in the separation layer's thickness, making it at least three times thinner than conventional polyamide thin films (which were previously limited to 100 nm). This remarkable breakthrough significantly boosts water flux, leading to a substantial enhancement in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles alongside specialized hydrophilic polymers has propelled advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance to unprecedented levels.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation heralds breakthroughs across four essential dimensions:
Self-Assembled Nanocomposite Films
By seamlessly integrating nano-scale precision control with nano-doping modification, we forge ultra-thin, highly ordered separation layers through advanced polymer interface nanotechnology. This avant-garde approach transcends the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Our meticulous optimization of the layer-by-layer self-assembly process allows for precise control of the functional layer's thickness, achieving a threefold reduction compared to traditional membranes. The outcome is >3x higher water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Unparalleled Chemical Stability
Progressing beyond polyamide, our team employs cutting-edge hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials exhibit remarkable oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (demonstrating stability across a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface design (contact angle <10°), fortified with nanoparticle reinforcement, effectively reduces organic fouling propensity by 50%. This innovation prolongs chemical cleaning cycles from 3 months to an impressive 6 months, thereby reducing maintenance costs by 40%.
