Farming applications

Water is crucial in ensuring the health and productivity of animals such as cattle, chickens, sheep, and pigs. Both the quantity and quality of water influence their growth and performance. We ensure optimum conditions through our advanced solutions.
Farm water can originate from various sources such as water wells, civil water networks, and occasionally from rivers and other surface sources. We offer solutions to cater to all these origins.
While civil network water may contain free chlorine, other sources often carry high levels of dissolved and suspended solids and pathogens. Reverse osmosis has proven to be the most efficient technology for mitigating these negative effects. Thus, we ensure contaminated farm water undergoes appropriate treatment to remove harmful substances, safeguarding animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
The application of desalination membranes on international luxury cruise ships has historically been dominated by a few international brands. The quality of feed water, such as salinity and temperature, fluctuates with the cruise ship's journey. Therefore, the membranes must adapt to different conditions while ensuring stable water production to meet the needs of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes demonstrated superior performance in both desalination rate and stable water production. The water quality produced by these membranes met the stringent requirements of the cruise ship.
This remarkable result led to the replacement of desalination membranes on three additional cruise ships. Proshare's success in this venture establishes it as the first national brand to win international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare Breakthrough Innovation in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has achieved remarkable strides in the realm of reverse osmosis membranes, leveraging advanced polymer interface nano-self-assembly technology to transcend the traditional barriers of membrane development with two groundbreaking advancements:
Revolutionary Ultra-Thin Separation Layer: Through cutting-edge polymer interface nanotechnology, we have ingeniously minimized the separation layer thickness to an unprecedented level, at least three times thinner than the conventional polyamide thin film (previously restrained to 100 nm). This innovation dramatically boosts water flux, realizing a remarkable surge in permeability.
Superior Enhanced Performance: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has led to transformative improvements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting new industry standards.
Compared to traditional polyamide reverse osmosis membranes, Proshare's pioneering technology exhibits remarkable advancements in four critical dimensions:
Innovative Self-Assembled Nanocomposite Films
With nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This revolutionary method surpasses the limitations of traditional polyamide membranes in both thickness uniformity and material diversity.
Significantly Enhanced Water Flux and Energy Efficiency
Through optimal layer-by-layer self-assembly, we precisely regulate the functional layer thickness, achieving a notable 3x reduction compared to conventional membranes. This innovation results in >3x augmented water flux and a significant 30% reduction in energy consumption.
Cutting-Edge Novel Polymer Materials with Unmatched Chemical Stability
Surpassing the limitations of polyamide, we employ state-of-the-art hydrophilic polymers (such as modified polysulfones) and innovative ceramic-organic hybrids. These materials demonstrate outstanding oxidation resistance (capable of withstanding up to 10 ppm chlorine exposure) and impressive pH tolerance (maintaining stability across a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface (contact angle <10°), reinforced with nanoparticles, minimizes organic fouling by 50%, extending chemical cleaning cycles from 3 to 6 months and significantly reducing maintenance costs by 40%.
