1. To guarantee peak performance, the permeate flow rate and stabilized salt rejection are determined under these meticulously verified standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) prior to undergoing hot water disinfection.
2. Be mindful that the permeate flow may vary by +/-15%, and the terminal water yield could fluctuate further due to
the involved heat treatment process.

For the pinnacle of animal health and productivity (encompassing cattle, chickens, sheep, and pigs), the quality of water is as vital as its abundance. Ensuring superior water quality is foundational in steering the desired growth and optimizing the performance of the animals.
Farm water can originate from a myriad of sources such as water wells, civil water networks, and occasionally from rivers and other surface sources, each with unique characteristics.
Excluding the chlorine-treated civil network water, alternate sources often bear substantial levels of dissolved and suspended solids and pathogens. Consequently, reverse osmosis technology emerges as the most efficient method to mitigate these impurities. It is crucial for farm water, particularly from non-civil sources, to undergo technological treatment to reduce harmful substances, ensuring the safety and well-being of the animals.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has pioneered an innovative breakthrough with the development of cutting-edge reverse osmosis membranes. By leveraging the transformative potential of polymer interface nano-self-assembly technology, we have shattered the traditional barriers in membrane development through two groundbreaking advancements:
Ultra-Thin Separation Layer: By skillfully employing polymer interface nanotechnology, our team has succeeded in crafting an incredibly thin separation layer, at least three times thinner than the conventional polyamide thin films, which were previously limited to 100 nm. This revolutionary reduction in thickness significantly boosts water flux, leading to a dramatic enhancement in permeability.
Enhanced Performance: By incorporating nanoparticles along with specially designed hydrophilic polymers, we have achieved unprecedented strides in enhancing the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation manifests in breakthroughs across four pivotal aspects:
Self-Assembled Nanocomposite Films
The convergence of nano-scale precision control with nano-doping modification enables the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This revolutionary technique overcomes the challenges in thickness uniformity and material diversity inherent in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we have precisely regulated the functional layer thickness, achieving an astounding 3x reduction compared to traditional membranes. This strategic advancement results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
In a significant advancement from polyamide, our team utilizes advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These state-of-the-art materials exhibit superior oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability within the 1-12 pH range).
Anti-Fouling Surface Engineering
