Farming applications

Water plays a crucial role in ensuring the well-being of animals like cattle, chickens, sheep, and pigs, directly impacting their productivity. It is not only the quantity of water but also its purity that influences the growth and performance of these animals.
The farm's water supply can be sourced from a variety of origins including water wells, civil water networks, and occasionally rivers or other surface sources.
Non-civil network water sources, often laden with high levels of dissolved and suspended solids and pathogens, require advanced treatment. Reverse osmosis technology emerges as the most effective method to mitigate these negative effects, ensuring that farm water is treated to remove harmful substances and safeguard 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 - A Pioneer in Innovative Membrane Solutions Our Team's Breakthrough in Pioneering Next-Gen Reverse Osmosis Membrane Technology
Proshare - Leading the Future of Filtration Our talented team has embarked on a groundbreaking journey, developing a new generation of reverse osmosis membranes. Harnessing the power of polymer interface nano-self-assembly technology, they have surmounted the traditional limitations seen in reverse osmosis membrane development with two revolutionary advancements:
Revolutionary Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has remarkably reduced the separation layer thickness to a third of what was previously possible with traditional polyamide films (which were capped at 100 nm). This innovation offers a remarkable boost in water flux and a significant leap in permeability.
Augmented Performance and Longevity: Through the strategic inclusion of nanoparticles and specially engineered hydrophilic polymers, we have spearheaded advancements that elevate the membrane's hydrophilicity, enhance its anti-fouling capabilities, and magnify its durability and oxidation resistance.
When set against the backdrop of conventional polyamide reverse osmosis membranes, Proshare's innovative approach shines with breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films - Redefining Membrane Precision
By integrating nano-scale precision control with nano-doping modifications, we craft ultra-thin and meticulously ordered separation layers using polymer interface nanotechnology. This pioneering approach triumphs over the constraints of conventional polyamide membranes, enhancing thickness uniformity and material versatility.
Superior Water Flux and Energy Efficiency
Our optimized layer-by-layer self-assembly process meticulously manages functional layer thickness, achieving a threefold reduction compared to traditional membranes. This precision engineering results in over 3x higher water flux coupled with a 30% decrease in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
Advancing beyond polyamide, we embrace state-of-the-art hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These materials demonstrate superior oxidation resistance (capable of enduring exposure to 10 ppm chlorine) and impressive pH resilience (ensuring stability across a pH spectrum of 1-12).
Cutting-Edge Anti-Fouling Surface Engineering
Featuring an ultra-hydrophilic surface (contact angle <10°) reinforced by nanoparticles, our design curtails organic fouling by 50%. This extends chemical cleaning intervals from three to six months, slashing maintenance expenses by 40%.
