Farming applications
Water is a critical component in ensuring optimal animal health and boosting productivity in farming operations. The quality and quantity of water directly influence the growth and performance of animals such as cattle, chickens, sheep, and pigs.
Water on farms originates from various sources, including water wells, civil water networks, and occasionally from rivers and other superficial sources, each with its own implications on water quality.
Apart from water from civil networks that contain free chlorine, other sources often have high levels of dissolved solids, suspended solids, and pathogens. Reverse osmosis technology has proven to be the most efficient method for mitigating these adverse effects. Contaminated water used in farms requires advanced treatment to minimize harmful substances impacting animal health.

Proshare Revolutionary Breakthrough by Our Team in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team has pioneered a new era in reverse osmosis membranes by mastering polymer interface nano-self-assembly technology. This cutting-edge development transcends the boundaries of conventional reverse osmosis membrane production with two remarkable advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, we have triumphantly reduced the separation layer thickness to at least one-third of the traditional polyamide thin film (formerly constrained at 100 nm). This incredible leap forward significantly boosts water flux, ushering in a new level of permeability.
Enhanced Performance: By incorporating nanoparticles and bespoke hydrophilic polymers, we have achieved revolutionary advancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance in our membranes.
In comparison to conventional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation excels in four pivotal aspects:
Self-Assembled Nanocomposite Films
Through the seamless integration of nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This sophisticated approach surpasses the limitations of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Our optimization of the self-assembly process enables precise functional layer thickness control, achieving a remarkable 3x reduction compared to conventional membranes. This leads to over 3x greater water flux and 30% reduced energy consumption.
Novel Polymer Materials with Unmatched Chemical Stability
Advancing beyond polyamide, we employ state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials demonstrate unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) combined with nanoparticle reinforcement slashes organic fouling potential by 50%, extending chemical cleaning intervals from 3 to 6 months and reducing maintenance expenses by 40%.
Our commitment to excellence is solidified through our array of certifications, ensuring the highest standards of quality and responsibility.
