Farming applications

Ensuring optimal water quality is crucial to guarantee the health and productivity of livestock, including cattle, chickens, sheep, and pigs. The quality of water is as pivotal as its quantity in influencing the animals' growth and performance.
Water on farms may originate from various sources, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources, all requiring careful management.
Given the high concentration of dissolved solids and pathogens in non-civil water sources, reverse osmosis technology proves to be the most effective method to mitigate these adverse effects. Proper technological treatment is essential to remove harmful substances from contaminated farm water, ensuring animal safety and health.

Proshare Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously crafted a revolutionary new generation of reverse osmosis membranes. Leveraging the transformative power of polymer interface nano-self-assembly technology, we have shattered the constraints of traditional membrane development through two monumental breakthroughs:
Ultra-Thin Separation Layer Innovation: Utilizing advanced polymer interface nanotechnology, our experts have successfully minimized the separation layer thickness to a groundbreaking level-at least three times thinner than conventional polyamide thin films, which had been constrained to 100 nm. This remarkable achievement dramatically boosts water permeability, resulting in a significant enhancement of water flux.
Revolutionized Performance: By incorporating cutting-edge nanoparticles and uniquely engineered hydrophilic polymers, we have unlocked extraordinary enhancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
When compared with traditional polyamide reverse osmosis membranes, Prosharetakes pride in offering innovations that excel in four pivotal areas:
Self-Assembled Nanocomposite Films: A Leap Forward
Through the seamless integration of nanoscale precision control and nano-doping modifications, we craft ultra-thin and meticulously ordered separation layers via advanced polymer interface nanotechnology. This method triumphs over the limitations of traditional polyamide membranes, ensuring superior thickness uniformity and expanded material diversity.
Maximized Water Flux and Optimized Energy Efficiency
Our optimized layer-by-layer self-assembly approach meticulously controls the functional layer thickness, achieving an impressive reduction by a factor of three compared to traditional membranes. This strategic precision leads to over three times the water flux and a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials Boasting Exceptional Chemical Stability
Beyond polyamide, our team harnesses the latest in advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These cutting-edge materials showcase extraordinary resistance to oxidation (withstanding exposure to up to 10 ppm chlorine) and robust pH tolerance (maintaining stability across a pH range of 1-12).
Revolutionary Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, complemented by nanoparticle reinforcement, effectively reduces the propensity for organic fouling by 50%. This advancement extends chemical cleaning cycles from 3 months to 6 months, significantly reducing maintenance costs by 40%.
