Farming applications
Water is indispensable for promoting the health and optimal productivity of farm animals such as cattle, chickens, sheep, and pigs. Beyond quantity, the quality of water plays an influential role in desired animal growth.
Farm water sources are varied, originating from wells, municipal water networks, and occasionally from rivers and surface water sources.
Except for municipal water (which contains free chlorine), other sources often contain high levels of dissolved and suspended solids, as well as pathogens. Reverse osmosis technology emerges as a superior solution to mitigate these adverse effects. Thus, it is crucial that contaminated farm water undergoes advanced treatment to reduce harmful substances that could impact animal health.

Proshare Unveiling Our Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has innovatively crafted a new era of reverse osmosis membranes using cutting-edge polymer interface nano-self-assembly technology. This remarkable achievement overcomes the constraints of traditional membrane development with two pivotal advancements:
Ultra-Thin Separation Layer Revolution: Leveraging the power of polymer interface nanotechnology, our team has remarkably reduced the separation layer thickness to an unprecedented level-at least three times thinner than the conventional polyamide thin film, which was previously restricted to 100 nm. This groundbreaking advancement significantly boosts water flux, marking a remarkable leap in permeability.
Enhanced Performance Pioneers: The infusion of nanoparticles and specially designed hydrophilic polymers has propelled the membrane to new heights, offering groundbreaking enhancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovative approach heralds breakthroughs in four critical aspects:
Ingenious Self-Assembled Nanocomposite Films
The synergy of nano-scale precision control and nano-doping modification empowers the creation of ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This advanced method conquers the limitations of conventional membranes in terms of thickness uniformity and material diversity.
Elevated Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we have achieved precise control over the functional layer thickness, resulting in a remarkable 3x reduction compared to traditional membranes. This leads to >3x enhanced water flux and a 30% reduction in energy consumption.
Cutting-Edge Polymer Materials with Exemplary Chemical Stability
Venturing beyond the typical polyamide, our team employs state-of-the-art hydrophilic polymers like modified polysulfones alongside ceramic-organic hybrids. These advanced materials demonstrate exceptional resistance to oxidation (enduring 10 ppm chlorine exposure) and tolerance to a wide pH range (remaining stable from pH 1 to 12).
