Farming applications

Water quality is crucial for ensuring the health and productivity of farm animals such as cattle, chickens, sheep, and pigs. Beyond mere quantity, the quality of water significantly impacts the desired growth and performance of these animals.
Farm water supplies can originate from various sources, such as water wells, civil water networks, and less commonly from rivers and other surface sources.
Excluding water from civil networks, which contains free chlorine, other sources often have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven highly effective in reducing these negative effects. Contaminated farm water should undergo technological treatment to eliminate substances harmful to animal health.

Our Advantages

Proshare Our Team's Revolutionary Leap in Cutting-Edge Reverse Osmosis Membrane Craftsmanship
Proshare Our pioneering team has ingeniously crafted a state-of-the-art generation of reverse osmosis membranes. Utilizing the breakthrough polymer interface nano-self-assembly technology, we have triumphantly surpassed the conventional constraints of traditional reverse osmosis membrane engineering through two monumental advancements:
Ultra-Thin Separation Layer: Through the strategic application of polymer interface nanotechnology, our expert team has remarkably reduced the separation layer's thickness to an unprecedented threefold reduction compared to traditional polyamide thin films, which were confined to 100 nm. This revolutionary achievement vastly elevates water flux, thus significantly boosting permeability.
Enhanced Performance: The infusion of cutting-edge nanoparticles coupled with specialized hydrophilic polymers has incited groundbreaking advancements in our membrane's hydrophilicity, anti-fouling capacity, durability, and heightened oxidation resistance.
When juxtaposed with traditional polyamide reverse osmosis membranes, Proshare's innovation marks profound breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By synthesizing nano-scale precision control with nano-doping modification, we meticulously craft ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This sophisticated approach transcends the inherent limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Unmatched Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we deftly control the functional layer thickness, achieving an astounding 3x reduction compared to traditional membranes. This mastery results in >3x elevated water flux alongside an impressive 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Progressing beyond polyamide, our team expertly employs advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials boast exceptional oxidation resistance (capable of enduring 10 ppm chlorine exposure) and pH tolerance (remaining stable across a 1-12 pH spectrum).
Pioneering Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (boasting a contact angle <10°) reinforced with nanoparticles notably diminishes organic fouling potential by 50%, extending the interval between chemical cleanings from 3 months to 6 months and remarkably slashing maintenance costs by 40%
