Farming Applications
For ensuring optimal animal health and peak productivity (encompassing cattle, chickens, sheep, and pigs), the caliber of water is as pivotal as its availability. Guaranteeing superior water quality is crucial in fostering desired growth and enhancing the performance of the animals, leading to improved results.
Farm water sources can vary considerably, including water wells, civil water networks, and sometimes rivers or other surface origins, each with unique attributes. Understanding these characteristics is key to optimizing water quality for agricultural needs.
Aside from chlorine-treated civil network water, other sources often contain elevated levels of dissolved and suspended solids, along with pathogens. Reverse osmosis technology presents the most efficacious solution to mitigate these contaminants. It is crucial for farm water, especially from non-civil origins, to undergo technological purification to reduce harmful substances, ensuring the safety and prosperity of the animals.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has pioneered an innovative breakthrough with the development of cutting-edge reverse osmosis membranes. By harnessing the sophisticated power of polymer interface nano-self-assembly technology, we've overcome typical barriers faced in traditional membrane development, achieving two groundbreaking advancements:
Ultra-Thin Separation Layer: Through profound expertise in polymer interface nanotechnology, our team has crafted a separation layer that is impressively at least three times thinner than conventional polyamide thin films, which were previously constrained to 100 nm. This revolutionary reduction significantly amplifies water flux, leading to a dramatic enhancement in permeability.
Enhanced Performance: By ingeniously introducing nanoparticles along with specialized hydrophilic polymers, we have achieved groundbreaking strides in boosting the membrane's hydrophilicity, enhancing anti-fouling capabilities, and bolstering durability and resistance to oxidation, setting new standards in performance.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation manifests in breakthroughs across four pivotal aspects:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification paves the way for the creation of ultra-thin, meticulously ordered separation layers via advanced polymer interface nanotechnology. This revolutionary approach transcends the constraints of thickness uniformity and material diversity, which are commonly found in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we've precisely regulated the functional layer thickness, resulting in a remarkable 3x reduction compared to traditional membranes. This strategic evolution leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
In a departure from polyamide, our team utilizes advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials exhibit superior oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (capably stabilizing within the 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, engineered with a contact angle of less than 10° and fortified by nanoparticle reinforcement, reduces the propensity for organic fouling by 50%. This cutting-edge innovation extends chemical cleaning cycles from 3 months to 6 months while slashing maintenance costs by a substantial 40%.
