Agricultural Applications
Water is a critical factor in ensuring the health and optimal performance of livestock, such as cattle, chickens, sheep, and pigs. The quality of water, not just its quantity, has a significant impact on the desired growth and productivity of these animals.
Water utilized in farms is sourced from various origins such as wells, civil water networks, and occasionally from rivers and other superficial sources.
Except for water from civil networks (which contains free chlorine), other sources typically have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method for mitigating these adverse effects. Contaminated farm water should undergo technological treatment to reduce harmful substances and protect animal health.

Proshare Innovation Suzhou Co., Ltd. Pioneering Breakthrough in Advanced Reverse Osmosis Membrane Technology
Proshare Innovation Suzhou Co., Ltd. Our dedicated team at Proshare has ingeniously crafted a cutting-edge generation of reverse osmosis membranes leveraging the state-of-the-art polymer interface nano-self-assembly technology, decisively surpassing the traditional constraints faced in reverse osmosis membrane development with two exceptional advancements:
Revolutionary Ultra-Thin Separation Layer: Utilizing the breakthrough polymer interface nanotechnology, our team has impressively minimized the separation layer's thickness to a groundbreaking level-at least three times thinner than the conventional polyamide thin film, which was previously limited to 100 nm. This revolutionary development significantly boosts water flux, resulting in a remarkable enhancement of permeability.
Unmatched Enhanced Performance: Through the strategic introduction of nanoparticles and specialized hydrophilic polymers, we have achieved unprecedented advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, pushing the boundaries of what's possible.
In comparison to traditional polyamide reverse osmosis membranes, Proshare Innovation Suzhou Co., Ltd.'s groundbreaking innovation showcases significant breakthroughs in four pivotal aspects:
Revolutionary Self-Assembled Nanocomposite Films
With the integration of nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This innovative method overcomes the longstanding limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Superior Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we achieve precise control over the functional layer thickness, resulting in a reduction to just a third of traditional membranes' thicknesses, thereby yielding more than three times higher water flux and a spectacular 30% reduction in energy consumption.
Advanced Novel Polymer Materials with Exceptional Chemical Stability
Surpassing the traditional polyamide approach, our team employs advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH resilience (remaining stable across a wide pH range of 1-12).
Innovative Anti-Fouling Surface Engineering
Our superhydrophilic surface, characterized by a contact angle of less than 10°, combined with nanoparticle reinforcement, significantly diminishes organic fouling propensity by an impressive 50%, thereby extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by a remarkable 40%
