Farming applications
Water is a vital component in ensuring the health and optimal performance of livestock, such as cattle, chickens, sheep, and pigs. However, both the quantity and quality of water are crucial factors affecting the desired growth and productivity of these animals.
Farms may source their water from a variety of origins, 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 typically feature high concentrations of dissolved and suspended solids as well as pathogens. Reverse osmosis technology has proven to be the most effective solution for mitigating these adverse effects. Contaminated water used on farms should undergo technological treatment to diminish substances harmful to animals.

Proshare Unparalleled Breakthrough in Next-Gen Reverse Osmosis Membrane Technology
Proshare rising above the traditional limitations, our pioneering team has ingeniously crafted an avant-garde reverse osmosis membrane. Leveraging the power of polymer interface nano-self-assembly technology, we've spearheaded two monumental advancements that redefine the future of filtration:
Revolutionary Ultra-Thin Separation Layer: Harnessing the cutting-edge of polymer interface nanotechnology, our team has achieved an incredible feat by slimming down the separation layer to a mere one-third of the traditional polyamide thin film's thickness, previously capped at 100 nm. This leap forward results in dramatically increased water flux, vastly boosting permeability.
Unmatched Performance Enhancement: By infusing nanoparticles and cutting-edge hydrophilic polymers, we've ushered in a new era of membrane performance, offering groundbreaking improvements in hydrophilicity, fouling resistance, robustness, and resilience to oxidation.
In stark contrast to conventional polyamide reverse osmosis membranes, Prosharedelivers unprecedented breakthroughs in four pivotal areas:
Pioneering Self-Assembled Nanocomposite Films
Through the meticulous integration of nano-scale precision control and nano-doping modification, we construct ultra-thin, precisely ordered separation layers utilizing advanced polymer interface nanotechnology. This innovation overcomes the traditional limitations of polyamide membranes by breaking barriers in thickness uniformity and expanding material versatility.
Astounding Water Flux and Energy Optimization
By refining the layer-by-layer self-assembly protocol, we've mastered functional layer thickness control, achieving a threefold reduction over conventional membranes. This advance results in over three times the water flux and a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Transcending polyamide boundaries, we utilize state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids, delivering extraordinary resistance to oxidation (withstanding exposure to 10 ppm chlorine) and superb pH resilience (stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, fortified by nanoparticle reinforcement, slashes organic fouling potential by half, doubling the interval of chemical cleaning cycles from 3 to 6 months, and slashing maintenance costs by a significant 40%.
Our unwavering commitment to quality and safety is demonstrated by our prestigious certifications. We proudly hold a Health & Safety Management System Certificate, an Environmental Management System Certificate, and the esteemed ISO9001 Quality System Certificate, showcasing our dedication to excellence across all facets of our operations.
At the forefront of innovation, we hold an Invention Patent for Membrane Production, as well as an Invention Patent for the groundbreaking Multi-layer RO Membrane. These patents highlight our pioneering advancements and our role as leaders in membrane technology. In adherence to the highest environmental and safety standards, we are pleased to announce our RoHS Compliance Certificate. This certification underscores our commitment to reducing hazardous substances and promoting a sustainable future.
