Farming applications

Water is crucial to ensure animal health (e.g., cattle, chickens, sheep, pigs) and optimize their performance. Both the quantity and quality of water can significantly influence desired growth outcomes.
Farm water sources can be diverse, such as water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Excluding civil network water (which contains free chlorine), other sources typically have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most efficient method to mitigate these negative effects. Therefore, contaminated farm water should be technologically treated to minimize substances that may harm the animals.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the realm of desalination membranes for international luxury cruise ships has been dominated by a select few global brands. The journey of these magnificent vessels presents challenges with fluctuating feed water quality, including salinity and temperature variations. Therefore, it is imperative that the membranes can seamlessly adapt to diverse conditions while consistently ensuring stable water production to meet the rigorous demands of ocean-going vessels.
Our PSI MEMBRANE Pro-HR-SW seawater desalination membranes have set a new benchmark in both desalination rate and the consistency of water production. These membranes produce water that not only meets but exceeds the stringent quality standards required by luxury cruise ships.
This extraordinary achievement led to the replacement of desalination membranes across three more cruise ships. Proshare's triumph in this endeavor heralds the emergence of a national brand as a formidable competitor, clinching international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare The Team's Pioneering Breakthrough in Advanced Reverse Osmosis Membrane Technology
Proshare team has ingeniously crafted a groundbreaking next-generation reverse osmosis membrane utilizing cutting-edge polymer interface nano-self-assembly technology, effectively transcending the constraints of conventional reverse osmosis membrane development through two pivotal enhancements:
Revolutionary Ultra-Thin Separation Layer: Leveraging state-of-the-art polymer interface nanotechnology, our team has ingeniously minimized the separation layer's thickness to a remarkable threefold reduction compared to the traditional polyamide thin film (which was previously limited to 100 nm). This pioneering advancement dramatically boosts water flux, leading to a significant leap in permeability.
Superior Enhanced Performance: The strategic incorporation of nanoparticles and bespoke hydrophilic polymers has resulted in transformative advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs in four critical areas:
Innovative Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification empowers the creation of ultra-thin, meticulously ordered separation layers via advanced polymer interface nanotechnology. This innovative approach successfully exceeds the limitations of conventional polyamide membranes in terms of thickness uniformity and diversity of materials.
Enhanced Water Flux and Optimized Energy Efficiency
Through precision refinement of the layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, achieving a reduction to 3x thinner than traditional membranes. This results in >3x enhanced water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Exceptional Chemical Stability
Advancing beyond conventional polyamide, our team employs cutting-edge hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials exhibit unparalleled oxidation resistance (capable of withstanding exposure to 10 ppm chlorine) and pH resilience (remain stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (with a contact angle of less than 10°) coupled with nanoparticle reinforcement significantly reduces the tendency for organic fouling by 50%, extending chemical cleaning cycles from 3 months to 6 months, thereby slashing maintenance costs by 40%.
