Farming applications

Water is vital for ensuring animal health and optimizing their productivity. While the volume of water is crucial, its quality is equally important in influencing the growth and performance of livestock such as cattle, chickens, sheep, and pigs.
Farm water can originate from various sources, including water wells, civil water networks, and, to a lesser extent, rivers and surface sources.
Excluding water from civil networks, which contains free chlorine, other sources often contain high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven most effective in mitigating these issues. Contaminated farm water requires advanced treatment to reduce harmful substances, ensuring it is safe for animal consumption.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the application of desalination membranes on international luxury cruise ships has predominantly been dominated by a select few global brands. As the cruise ship navigates through various waters, the quality of feed water changes, with salinity and temperature fluctuating along the journey. Consequently, these membranes must be resilient, adapting to diverse conditions, all while ensuring consistent water production to satisfy the stringent demands of ocean-going vessels.
Proshare's PSI MEMBRANE Pro-HR-SW seawater desalination membranes exemplify outstanding performance, delivering exceptional desalination rates and consistent water production. The resulting water quality not only meets but exceeds the rigorous standards required by luxury cruise ships.
This exceptional achievement facilitated the replacement of desalination membranes on three additional cruise ships. Proshare's triumph in this arena marks a historic milestone as the first national brand to secure international luxury cruise ship contracts for desalination RO membranes.

Our Advantages

Proshare Team's Revolutionary Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare team has brilliantly pioneered a next-generation class of reverse osmosis membranes, engineered through state-of-the-art polymer interface nano-self-assembly technology. This innovation transcends the traditional barriers faced in reverse osmosis membrane development with two key revolutionary advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our expert team has dramatically reduced the thickness of the separation layer, making it at least three times slimmer than conventional polyamide thin films, which were previously confined to a minimum of 100 nm. This groundbreaking advancement greatly amplifies water flux, leading to an exceptional increase in permeability, setting new performance benchmarks.
Enhanced Performance: Through the strategic infusion of nanoparticles and innovative hydrophilic polymers, we have achieved monumental strides in augmenting the membrane's hydrophilicity, anti-fouling capabilities, durability, and resilience against oxidation, redefining the standards of membrane performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases remarkable advancements in four pivotal dimensions:
Self-Assembled Nanocomposite Films
The sophisticated blend of nano-scale precision control and nano-doping modification empowers the construction of ultra-thin, meticulously organized separation layers via polymer interface nanotechnology. This innovative approach triumphs over the constraints of conventional polyamide membranes, particularly in achieving unparalleled thickness uniformity and expanding material diversity.
Enhanced Water Flux and Energy Efficiency
By attaining mastery over the layer-by-layer self-assembly process, we precisely regulate the thickness of the functional layer, realizing a 3x reduction compared to traditional membranes. This leap forward delivers >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Unmatched Chemical Stability
Advancing beyond the limitations of polyamide, our team leverages cutting-edge hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These innovative materials exhibit outstanding oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability in a broad pH range from 1 to 12).
Anti-Fouling Surface Engineering
Our advanced engineering delivers a superhydrophilic surface (contact angle <10°) that, when combined with nanoparticle enhancement, remarkably reduces the organic fouling propensity by 50%. This innovation extends chemical cleaning cycles from every 3 months to every 6 months, substantially lowering maintenance costs by 40%, forging a new era of cost efficiency and sustainability.
