Farming applications
Water is crucial for ensuring the health and optimal productivity of livestock such as cattle, chickens, sheep, and pigs. Beyond quantity, the water's quality is pivotal to achieving the desired growth and performance of these animals.
Farms may source water from a variety of origins, including wells, civil water networks, and, less commonly, from rivers and other surface sources.
Excluding water sourced from civil networks, which contains free chlorine, other water sources often have high levels of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology emerges as the most effective solution to mitigate these negative impacts. Contaminated farm water should undergo technological treatment to reduce harmful substances and ensure the well-being of the animals.

Proshare A Remarkable Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our dedicated team at Proshare has pioneered a revolutionary advancement in reverse osmosis membranes, utilizing state-of-the-art polymer interface nano-self-assembly technology. This groundbreaking innovation effectively surmounts the traditional constraints of reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has astoundingly minimized the separation layer's thickness to three times thinner than the conventional polyamide thin film, historically capped at 100 nm. This monumental breakthrough markedly boosts water flux, resulting in a remarkable enhancement in permeability.
Enhanced Performance: By introducing nanoparticles and specialized hydrophilic polymers, we have achieved unprecedented progress in the membrane's hydrophilicity, anti-fouling capacity, longevity, and oxidation resistance.
In comparison with traditional polyamide reverse osmosis membranes, Proshare's innovation reveals remarkable breakthroughs across four crucial dimensions:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control and nano-doping modification, Proshare has crafted ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This sophisticated method triumphs over the typical limitations of conventional polyamide membranes, such as thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, resulting in a significant 3x reduction compared to traditional membranes. This advancement culminates in >3x higher water flux and 30% reduced energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Beyond the realm of polyamide, our team leverages state-of-the-art hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids, which exhibit outstanding oxidation resistance (withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability across the 1-12 pH spectrum).
Innovative Anti-Fouling Surface Engineering
Our superhydrophilic surface, featuring a contact angle of less than 10°, combined with nanoparticle reinforcement, effectively curbs organic fouling by 50%. This advancement prolongs chemical cleaning intervals from every 3 months to every 6 months, resulting in a 40% reduction in maintenance costs.
