Farming Applications
Ensuring optimal animal health and productivity (including cattle, chickens, sheep, and pigs) hinges as much on the water's quality as its availability. Delivering premium water quality is crucial in achieving desired growth and maximizing animal performance.
Farm water might originate from various sources such as water wells, civil water networks, and occasionally from rivers and other surface sources, each presenting unique characteristics.
Aside from chlorine-treated civil network water, other sources often harbor high levels of dissolved and suspended solids and pathogens. Thus, reverse osmosis technology proves to be the most potent method to address these contaminants. It is imperative for farm water, especially from non-civil sources, to undergo technological treatment to reduce harmful substances, ensuring the safety and well-being of the animals.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has achieved a revolutionary leap forward with the development of state-of-the-art reverse osmosis membranes. Utilizing the groundbreaking polymer interface nano-self-assembly technology, we have navigated beyond the traditional barriers in membrane development through two monumental advancements:
Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, our team has crafted a separation layer that is substantially thinner-at a minimum of three times slimmer-than the conventional 100 nm polyamide thin films. This significant reduction in thickness not only amplifies water flux but also delivers a dramatic improvement in permeability.
Enhanced Performance: Through the strategic integration of nanoparticles and bespoke hydrophilic polymers, we have realized unprecedented advancements in elevating the membrane's hydrophilicity, anti-fouling capabilities, longevity, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation is encapsulated in breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
By merging nano-scale precision control with nano-doping modification, we have engineered ultra-thin, intricately ordered separation layers through polymer interface nanotechnology. This revolutionary approach transcends the limitations of thickness uniformity and material diversity typically associated with conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we have precisely calibrated the functional layer thickness, achieving a remarkable reduction by a factor of 3 compared to traditional membranes. This strategic advancement results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking away from traditional polyamide, our team utilizes advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These pioneering materials demonstrate exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability within a 1-12 pH range).
Anti-Fouling Surface Engineering
Our ultra-superhydrophilic surface, designed with a contact angle less than 10° and reinforced with nanoparticles, significantly reduces the likelihood of organic fouling by 50%. This cutting-edge innovation extends chemical cleaning cycles from 3 to 6 months, while reducing maintenance costs by an impressive 40%.
