Farming Applications

Water is vital to ensure the health and productivity of animals (e.g., cattle, chickens, sheep, pigs), impacting not only their growth but also overall performance. The quality, in addition to the quantity of water, plays a pivotal role in achieving optimum animal productivity.
Farm water can originate from various sources, including water wells, civil water networks, and to a lesser degree, rivers, and other surface sources.
Excluding chlorinated water from civil networks, other sources often harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be supremely effective in mitigating these negative impacts. Consequently, farm water should undergo advanced technological treatment to diminish harmful substances, safeguarding animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
The deployment of desalination membranes on luxury international cruise ships has been predominantly led by renowned international brands. The cruise's journey brings varying feed water quality, with fluctuations in salinity and temperature. As a result, the membranes are required to be adaptable to these diverse conditions while ensuring consistent water output that fulfills the demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes from Proshare exhibited exceptional performance in both desalination efficiency and consistent water production. The water quality achieved by these membranes successfully met the rigorous standards expected by cruise ships.
This outstanding performance paved the way for the replacement of desalination membranes on three more cruise ships. Proshare's triumph in this endeavor marks it as the pioneering national brand to secure international luxury cruise ship contracts for desalination RO membranes.

A Complete Water Treatment Plant for Generating Ultra-pure Water in Semiconductor Industry

As is well-known, the requirements for electronic-grade ultra-pure water in membrane desalination are extraordinarily high, with only a select few brands capable of meeting these stringent demands.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has pioneered a remarkable new generation of reverse osmosis membranes, building on cutting-edge polymer interface nano-self-assembly technology. Overcoming the barriers faced by traditional reverse osmosis membrane development, we have achieved significant progress through two monumental innovations:
Ultra-Thin Separation Layer: By harnessing the power of advanced polymer interface nanotechnology, we've ingeniously reduced the thickness of the separation layer to an unprecedented level-at least three times thinner than conventional polyamide thin films, previously capped at 100 nm. This revolutionary advancement dramatically boosts water flux, setting a new benchmark in permeability.
Enhanced Performance: Introducing cutting-edge nanoparticles and unique hydrophilic polymers has ushered in transformative enhancements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation marks breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
Leveraging nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers using state-of-the-art polymer interface nanotechnology. This innovative method transcends the conventional polyamide membranes' limitations in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Optimizing the layer-by-layer self-assembly process allows for precise control over functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This optimization delivers >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Our team has transcended polyamide limitations by employing cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°), reinforced with nanoparticles, effectively slashes organic fouling by 50%, doubling the interval between chemical cleaning cycles to 6 months and reducing maintenance costs by an impressive 40%.
