Farming applications

Water quality is crucial for optimizing animal health and productivity (e.g., cattle, poultry, sheep, swine). Beyond mere quantity, superior water quality significantly influences desired growth and performance outcomes.
Water sourced for farming can originate from various avenues, including wells, municipal networks, and, less frequently, natural sources such as rivers.
Excluding municipal networks with chlorinated water, alternative sources often carry high levels of dissolved and suspended solids along with pathogens. Reverse osmosis technology emerges as the most effective method to mitigate these contaminants, ensuring that water used on farms is treated to minimize harmful substances for livestock.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Traditionally, the application of desalination membranes on international luxury cruise ships was a domain reserved for a select few global brands. The journey of a cruise ship often comes with varying feed water quality parameters, such as salinity and temperature, which shift as the vessel traverses different waters. Therefore, it is imperative that the membranes can adapt to these diverse conditions while consistently ensuring the production of stable, high-quality water to cater to the needs of these ocean giants.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have showcased exceptional performance by achieving an impressive desalination rate coupled with a stable water production rate. The water quality produced by these membranes has met and exceeded the stringent standards imposed by luxury cruise ships.
This extraordinary success resulted in the replacement of desalination membranes on three additional luxury cruise ships.

Proshare Pioneering Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our innovative team has masterfully crafted a groundbreaking generation of reverse osmosis membranes, using pioneering polymer interface nano-self-assembly technology. This remarkable achievement transcends the traditional constraints, thanks to two phenomenal advancements:
Revolutionary Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, the team has achieved a revolutionary reduction in the separation layer's thickness, creating layers that are at least three times thinner than conventional polyamide films (previously capped at 100 nm). This extraordinary achievement significantly elevates water flux and heralds a notable leap in permeability.
Remarkably Enhanced Performance: By integrating nanoparticles and specialized hydrophilic polymers, the team has ushered in transformative enhancements in the membrane's properties such as hydrophilicity, anti-fouling capability, durability, and robust oxidation resistance.
In contrast to conventional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases remarkable breakthroughs across four pivotal dimensions:
Innovative Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, ultra-thin, highly ordered separation layers are crafted with polymer interface nanotechnology. This advanced method surpasses the limitations of traditional polyamide membranes, ensuring unmatched thickness uniformity and material diversity.
Superior Water Flux and Exceptional Energy Efficiency
With precise optimization of the layer-by-layer self-assembly process, the functional layer's thickness is expertly controlled, achieving a striking 3x reduction compared to traditional membranes. This innovation results in >3x greater water flux and an impressive 30% reduction in energy consumption.
Novel Polymer Materials with Unrivaled Chemical Stability
Extending beyond polyamide, advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids are utilized, offering remarkable oxidation resistance (withstanding 10 ppm chlorine exposure) and outstanding pH tolerance (maintaining stability within a 1-12 pH range).
