Farming applications
Water is a vital element to ensure the optimal health and productivity of farm animals such as cattle, chickens, sheep, and pigs. The quantity and, more importantly, the quality of water directly impact the animals' growth and performance, making it a critical factor in farming operations.
Farm water can originate from various sources, including water wells, civil water networks, and occasionally from 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. Reverse osmosis technology stands as the most effective solution to mitigate these adverse effects. Contaminated farm water should undergo technological treatment to diminish harmful substances, protecting animal health and ensuring optimal growth.

Proshare Trailblazing Innovations in the Next Level of Reverse Osmosis Membrane Technology
Proshare Our dynamic team has ingeniously crafted a cutting-edge generation of reverse osmosis membranes utilizing polymer interface nano-self-assembly technology. This revolutionary approach triumphs over the constraints of traditional reverse osmosis membrane development, marked by two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Leveraging the power of polymer interface nanotechnology, our team has masterfully thinned the separation layer, achieving a remarkable reduction in thickness to at least three times thinner than conventional polyamide thin films, which were previously confined to a thickness of 100 nm. This phenomenal breakthrough amplifies water flux and delivers a significant boost in permeability.
Augmented Performance and Resilience: The infusion of nanoparticles alongside specialized hydrophilic polymers has ushered in monumental advancements in enhancing the membrane's hydrophilicity, anti-fouling capabilities, robustness, and oxidation resistance, setting new benchmarks in membrane performance.
In stark contrast to conventional polyamide reverse osmosis membranes, Proshare's pioneering innovation showcases breakthroughs across four fundamental dimensions:
Revolutionary Self-Assembled Nanocomposite Films
With the strategic integration of nano-scale precision control and nano-doping modifications, we craft ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This sophisticated method addresses the challenges of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Elevated Water Flux and Enhanced Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer's thickness, achieving an astounding 3x reduction relative to traditional membranes. This precision engineering translates to over 3 times higher water flux and 30% reduced energy consumption.
Innovative Polymer Materials with Superior Chemical Endurance
Surpassing the confines of polyamide, our team employs advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These avant-garde materials showcase exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and wide-ranging pH tolerance (remaining stable within a pH range of 1-12).
Revolutionary Anti-Fouling Surface Engineering
The superhydrophilic surface (boasting a contact angle of less than 10°), reinforced with nanoparticles, dramatically reduces the tendency for organic fouling by 50%, thereby extending chemical cleaning intervals from 3 months to an impressive 6 months and slashing maintenance costs by 40%.
