1. To guarantee optimal performance, the permeate flow rate and stabilized salt rejection are meticulously based on the following rigorously tested 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 any hot water disinfection.
2. Please be aware, the variation range of permeate flow is +/-15%, and the final water yield may experience additional fluctuations due to
the specific heat treatment processes involved.

Ensuring optimal animal health and productivity (spanning cattle, chickens, sheep, and pigs) hinges as much on water quality as it does on its availability. Superior water quality is vital in fostering desired growth and maximizing animal performance.
Farm water can originate from various sources, including water wells, civil water networks, and occasionally rivers and other surface sources, each possessing unique characteristics.
Apart from chlorine-treated civil network water, other sources often contain elevated levels of dissolved and suspended solids and pathogens. Thus, reverse osmosis technology stands out as the most effective method to reduce these contaminants. It is crucial for farm water, especially from non-civil sources, to undergo technological treatment to diminish harmful substances, ensuring the safety and well-being of the animals.

ProshareRevolutionary Breakthrough by Our Team in Advanced Reverse Osmosis Membrane Technology
ProshareOur pioneering team has achieved an extraordinary breakthrough with the creation of state-of-the-art reverse osmosis membranes. By leveraging the advanced capabilities of polymer interface nano-self-assembly technology, we have shattered the conventional barriers in membrane development through two transformative innovations:
Ultra-Thin Separation Layer: With the expert application of polymer interface nanotechnology, our team has crafted a remarkably thin separation layer, achieving a thickness three times less than traditional polyamide thin films, which were previously bound to 100 nm. This groundbreaking reduction in thickness significantly enhances water flux, resulting in a dramatic increase in permeability.
Superior Performance Enhancement: Through the integration of nanoparticles coupled with specialized hydrophilic polymers, we have made groundbreaking advancements in elevating the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
In comparison to conventional polyamide reverse osmosis membranes,Proshare's groundbreaking innovation shines through in four critical dimensions:
Self-Assembled Nanocomposite Films
By uniting nano-scale precision control with nano-doping modification, we have achieved the formation of ultra-thin, impeccably ordered separation layers using polymer interface nanotechnology. This revolutionary technique transcends the limitations of thickness uniformity and material diversity found in traditional polyamide membranes.
Enhanced Water Flux and Energy Optimization
Through meticulous optimization of the layer-by-layer self-assembly process, we have precisely regulated the functional layer thickness to achieve an astounding 3x reduction compared to traditional membranes. This strategic advancement culminates in >3x increased water flux and 30% reduced energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Breaking away from polyamide, we employ advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These innovative materials exhibit outstanding oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability within the 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
Our ultra-hydrophilic surface, designed with a contact angle under 10° and reinforced with nanoparticles, reduces the likelihood of organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 months to 6 months, while cutting maintenance costs by 40%.
