1. The permeate flow rate and stable salt rejection are determined under these rigorous standard test conditions:

For NF membranes, testing occurs with a 2000ppm MgSO4 solution at 0.48 MPa and 25ºC, with a 15% recovery rate. RO membranes undergo testing with a 2000ppm NaCl solution,

at 1.55 MPa and 25ºC, also achieving a 15% recovery rate, prior to any hot water disinfection processes.

2. The permeate flow variation may range within +/-15%, with additional fluctuations potentially arising due to

the thermal treatment methodologies involved.

Farming applications

Water is pivotal for ensuring the well-being of farm animals (such as cattle, chickens, sheep, pigs) and achieving optimal productive performance. The quality of water, in addition to quantity, plays a crucial role in influencing the desired growth of animals.
On farms, water can originate from various sources, including water wells, civil water networks, and, to a lesser degree, rivers and other surface sources.
Aside from water from civil networks (which contains free chlorine), other sources typically have high levels of dissolved and suspended solids and pathogens. As such, reverse osmosis technology has proven to be the most effective method for mitigating their adverse effects. Contaminated farm water should be technologically treated to reduce substances harmful to animals.

Our Advantages

Proshare Revolutionizing Reverse Osmosis: Team's Breakthrough in Next-Generation Membrane Technology
Proshare Our dedicated team has ingeniously pioneered a state-of-the-art generation of reverse osmosis membranes, harnessing polymer interface nano-self-assembly technology. This cutting-edge approach triumphs over the constraints faced by traditional reverse osmosis membrane development, thanks to two groundbreaking advancements:
Ultra-Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, our team has effectively minimized the separation layer's thickness to a remarkable extent-three times thinner than the standard polyamide thin film (historically restricted to 100 nm). This monumental breakthrough dramatically increases water flux, ushering in a substantial leap in permeability.
Unparalleled Performance Enhancement: The innovative incorporation of nanoparticles and specialized hydrophilic polymers has catalyzed remarkable advancements in the membrane's hydrophilicity, anti-fouling capacity, durability, and resistance to oxidation.
When compared to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By seamlessly blending nano-scale precision control with nano-doping modification, this technology enables the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This revolutionary methodology surmounts the traditional polyamide membranes' challenges of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, the functional layer achieves precise thickness control, leading to a remarkable 3x reduction compared to conventional membranes. This precision engineering results in over 3x higher water flux alongside a 30% decrease in energy consumption.
Novel Polymer Materials with Exceptional Chemical Stability
Venturing beyond the confines of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and innovative ceramic-organic hybrids. These advanced materials exhibit unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The development of a superhydrophilic surface (contact angle <10°) in tandem with nanoparticle reinforcement dramatically diminishes organic fouling propensity by 50%, thereby extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by 40%.
