Farming Applications

In farming, water is vital to ensure the health and productivity of animals such as cattle, chickens, sheep, and pigs. The water's quality, not just its quantity, plays a crucial role in supporting their optimal growth and performance.
Farm water can originate from various sources including water wells, civil water networks, and to a lesser extent, rivers and other surface sources.
Excluding water from civil networks, which contains free chlorine, other sources often harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology is proven to be the most effective method to mitigate these adverse effects, ensuring that farm water undergoes necessary technological treatment to remove substances harmful to animal health.

Our Advantages

Proshare: Redefining Membrane Innovation The Team's Breakthrough in Pioneering Next-Generation Reverse Osmosis Membrane Technology
At Proshare, we are at the forefront of membrane innovation. Our pioneering team has revolutionized the development of a new era in reverse osmosis membranes. By utilizing cutting-edge polymer interface nano-self-assembly technology, we've surmounted the challenges inherent in traditional membrane development through two transformative advancements:
Ultra-Thin and Efficient Separation Layer: Harnessing the power of polymer interface nanotechnology, our team achieved a dramatic reduction in the thickness of the separation layer, making it at least three times thinner than the conventional polyamide thin film, which was previously capped at 100 nm. This landmark achievement leads to a remarkable boost in water flux, significantly enhancing permeability and efficiency.
Enhanced Performance and Durability: With the strategic addition of nanoparticles and specialized hydrophilic polymers, our membranes exhibit unprecedented advancements in hydrophilicity, anti-fouling capacity, durability, and resistance to oxidation, setting a new standard in performance.
In stark contrast to traditional polyamide reverse osmosis membranes, Proshare'sinnovation showcases breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films, Redefining Precision
Through the fusion of nano-scale precision control and nano-doping modification, we achieve ultra-thin, highly ordered separation layers via advanced polymer interface nanotechnology. This innovative approach transcends the limitations of conventional polyamide membranes, offering superior thickness uniformity and material diversity.
Enhanced Water Flux and Optimized Energy Efficiency
By refining the layer-by-layer self-assembly process, we achieve precise control over functional layer thickness, resulting in a significant 3x reduction compared to traditional membranes. This innovation translates to over three times the water flux and 30% reduction in energy consumption- a testament to our commitment to efficiency.
Novel Polymer Materials Delivering Superior Chemical Stability
Surpassing the capabilities of polyamide, we employ cutting-edge hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These advanced materials boast remarkable oxidation resistance (withstanding exposure to 10 ppm chlorine) and broad pH tolerance (maintaining stability across a pH range of 1 to 12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, drastically reduces organic fouling propensity by 50%. This advancement extends chemical cleaning intervals from three to six months, achieving a 40% reduction in maintenance costs.
