Water is critical to ensuring the health and optimal productivity of farm animals such as cattle, chickens, sheep, and pigs. Both water quality and quantity play essential roles in achieving desired growth and animal performance.
Farm water can originate from various sources, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. We provide tailored solutions for each scenario.
While water from civil networks typically contains free chlorine, other sources often have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology stands out as the most effective method to mitigate these negative effects. Contaminated farm water requires technological treatment to reduce 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 international luxury cruise liners has traditionally been led by a select few international brands. As these ships traverse the oceans, the quality of feed water-encompassing variables like salinity and temperature-varies. Consequently, the membranes must seamlessly adapt to diverse conditions while maintaining consistent water production levels to satisfy the rigorous demands of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes have set a new benchmark with their remarkable desalination efficiency and reliable water production capabilities. The water quality achieved by these membranes meets the highest standards required by luxury cruise ships.
This extraordinary outcome prompted the replacement of desalination membranes on three additional cruise ships. Proshare's triumph in this endeavor positions it as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare The Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The dedicated team at Proshare has pioneered a revolutionary development in reverse osmosis membranes, utilizing groundbreaking polymer interface nano-self-assembly technology. This innovative approach surpasses the constraints of traditional membrane technologies, marking two monumental advancements:
Ultra-Thin Separation Layer: Leveraging cutting-edge polymer interface nanotechnology, our team has ingeniously diminished the separation layer's thickness to an unprecedented level-at least threefold thinner than the conventional polyamide thin film, which was previously constrained to 100 nm. This remarkable progression vastly amplifies water flux, resulting in a dramatic enhancement of permeability.
Enhanced Performance: Through the strategic incorporation of nanoparticles and specialized hydrophilic polymers, we have unlocked groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capacities, durability, and resistance to oxidation.
In contrast with traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs in four critical dimensions:
Self-Assembled Nanocomposite Films
By harmonizing nano-scale precision control with nano-doping modification, we can construct ultra-thin, meticulously ordered separation layers using advanced polymer interface nanotechnology. This method overcomes the typical challenges faced by conventional polyamide membranes concerning thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By refining our layer-by-layer self-assembly process, we achieve precise control over the functional layer's thickness, making it three times thinner than traditional membranes. This innovation facilitates more than triple the water flux while reducing energy consumption by 30%.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, we employ state-of-the-art hydrophilic polymers such as modified polysulfones and innovative ceramic-organic hybrids. These groundbreaking materials offer remarkable resistance to oxidation (withstanding exposure to up to 10 ppm chlorine) and broad pH tolerance (maintaining stability across a pH range from 1 to 12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, reinforced by nanoparticles, diminishes organic fouling potential by 50%. This extends the intervals between chemical cleaning from 3 to 6 months and significantly reduces maintenance costs by 40%.
