Farming Applications

Water plays a critical role in maintaining the health and productivity of livestock, including cattle, chickens, sheep, and pigs. It is not only the quantity but also the quality of the water that affects the growth and performance of the animals.
On farms, water may originate from various sources such as wells, civil water networks, and occasionally from rivers and other surface sources.
Excluding civil networks (which contain free chlorine), other water sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be highly efficient in mitigating these adverse effects. As such, contaminated farm water should undergo technological treatment to minimize harmful substances that could affect animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the application of desalination membranes on international luxury cruise ships has been dominated by a few global giants. As the cruise ship navigates across diverse waters, the quality of feed water, including salinity and temperature, varies significantly. Hence, the membranes must exhibit remarkable adaptability to various conditions while consistently ensuring stable and high-quality water production to cater to the demanding needs of these oceanic vessels.

Our Advantages

Proshare Revolutionizing Reverse Osmosis: Proshare's Team Breakthrough
Proshare Our innovative team has crafted a groundbreaking new generation of reverse osmosis membranes, leveraging the power of polymer interface nano-self-assembly technology. We have transcended traditional development barriers with two pivotal advancements:
Ultra-Thin Separation Layer: Through pioneering polymer interface nanotechnology, we have successfully achieved a separation layer at least three times thinner than the conventional 100 nm polyamide films. This landmark enhancement dramatically boosts water flux, resulting in a marked increase in permeability.
Enhanced Performance: With the strategic introduction of nanoparticles and specialized hydrophilic polymers, our membranes exhibit unrivaled hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting new standards for performance.
When compared to conventional polyamide reverse osmosis membranes, Proshare's ingenuity shines through with four transformative breakthroughs:
Self-Assembled Nanocomposite Films
Through advanced nano-scale precision control and innovative nano-doping modification, we forge ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This method surpasses the challenges of conventional polyamide membranes in achieving consistent thickness and material variety.
Enhanced Water Flux and Energy Efficiency
By perfecting our layer-by-layer self-assembly technique, we precisely manage functional layer thickness, slashing it by 3x compared to traditional methods. This results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Progressing beyond polyamide, we employ cutting-edge hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These materials demonstrate exceptional oxidation resistance (able to withstand exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across the 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, paired with reinforced nanoparticles, reduces organic fouling by 50%. This innovation extends the intervals between chemical cleanings from 3 to 6 months and cuts maintenance costs by 40%.
