1. The permeate flow rate and stabilized salt rejection metrics are derived based on these standard test conditions:

For NF membranes: 2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery. For RO membranes: 2000ppm NaCl solution,

1.55 MPa, 25ºC, 15% recovery. These conditions are observed prior to any hot water disinfection procedures.

2. Note that permeate flow variation may range +/-15%, with potential fluctuations in final water yield due to

the intricacies of the heat treatment process.

Farming Applications

Water is indispensable to ensure the health and productivity of animals such as cattle, chickens, sheep, and pigs. While the quantity of water is crucial, its quality plays an equally significant role in achieving optimal animal growth and productivity.
Farms utilize water from various sources, including water wells, civil water networks, and occasionally from rivers and other surface sources.
Aside from water sourced from civil networks, often containing free chlorine, other sources generally present a high concentration of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology stands out as the most efficient solution to mitigate these issues, ensuring that contaminated farm water undergoes meticulous treatment to remove harmful substances and safeguard animal health.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the application of desalination membranes on international luxury cruise ships has been dominated by a select few global brands. As the cruise ship travels, the quality of feed water, including salinity and temperature, naturally fluctuates, requiring membranes that can effortlessly adapt while maintaining consistent water production, crucial for meeting the demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes exhibited exceptional performance, providing both an impressive desalination rate and consistent water output. The resulting water quality conformed to the strict standards set by luxury cruise ships.
This outstanding achievement led to the replacement of existing desalination membranes on three more cruise ships. Proshare emerges as a pioneering national brand, securing orders for desalination RO membranes on international luxury cruise ships.

Our Advantages

Proshare Revolutionary Advances in Next-Gen Reverse Osmosis Membrane Technology
Proshare Our dedicated team has pioneeringly crafted a cutting-edge generation of reverse osmosis membranes rooted in polymer interface nano-self-assembly technology, surmounting the conventional limitations of traditional reverse osmosis membrane progress through two remarkable technological strides:
Breakthrough Ultra-Thin Separation Layer: By harnessing advanced polymer interface nanotechnology, our team has impressively minimized the thickness of the separation layer to be more than three times thinner than traditional polyamide thin films (historically constrained to 100 nm). This extraordinary achievement notably boosts water flux, delivering a profound leap in permeability.
Unmatched Performance Enhancement: The strategic infusion of nanoparticles and uniquely tailored hydrophilic polymers has catalyzed transformative advancements in the membrane's hydrophilicity, anti-fouling prowess, durability, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation symbolizes pioneering breakthroughs in four pivotal areas:
Revolutionary Self-Assembled Nanocomposite Films
Through the synthesis of nano-scale precision control and nano-doping modification, we have innovatively constructed ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This avant-garde approach surpasses the constraints of conventional polyamide membranes in terms of thickness uniformity and material variety.
Advanced Water Flux and Enhanced Energy Efficiency
By refining the layer-by-layer self-assembly process, we precisely govern the functional layer thickness, realizing a remarkable 3x reduction when compared to traditional membranes. This precision engineering delivers >3x superior water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Unrivaled Chemical Stability
Venturing beyond polyamide, our team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids, which exhibit outstanding oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a 1-12 pH range).
Sophisticated Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (boasting a contact angle of less than 10°) combined with nanoparticle reinforcement dramatically decreases organic fouling potential by 50%, prolonging chemical cleaning intervals from 3 months to an impressive 6 months, thereby slashing maintenance expenses by 40%
