Farming applications

Water quality is crucial for ensuring the health and optimal performance of farm animals like cattle, chickens, sheep, and pigs. While quantity is significant, the quality of water is equally vital for promoting desired growth outcomes.
Farms utilize water from various sources, including wells, municipal water networks, and occasionally from surface sources like rivers. The origin of the water directly impacts its quality and suitability for use.
Apart from municipal network water, which contains free chlorine, other sources often present high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be an effective solution for minimizing these negative impacts. Therefore, treating farm water is essential to remove harmful substances and safeguard animal health.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has ingeniously pioneered a new era of reverse osmosis membranes using cutting-edge polymer interface nano-self-assembly technology, triumphing over the constraints of traditional development with two pivotal innovations:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, our team has remarkably minimized the separation layer's thickness to three times less than the typical 100 nm barrier of polyamide thin films. This revolutionary stride drastically heightens water flux, leading to an extraordinary leap in permeability.
Enhanced Performance: By incorporating nanoparticles and specialized hydrophilic polymers, we've achieved unprecedented advancements in hydrophilicity, anti-fouling ability, longevity, and oxidation resilience of the membrane.
Compared to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation marks breakthroughs in four vital dimensions:
Self-Assembled Nanocomposite Films
Through nano-scale precision control and nano-doping modification, we've crafted ultra-thin, meticulously ordered separation layers with polymer interface nanotechnology. This ingenious approach transcends conventional limits in polyamide membrane thickness and material versatility.
Enhanced Water Flux and Energy Efficiency
Our meticulous optimization of the layer-by-layer self-assembly process allows us to finely tailor the functional layer thickness, achieving a substantial 3x reduction versus traditional membranes. This results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Departing from polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids, which showcase remarkable oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
Our exceptionally hydrophilic surface (contact angle <10°), fortified with nanoparticle reinforcement, slashes organic fouling likelihood by 50%. This advancement extends chemical cleaning cycles from 3 to 6 months and reduces maintenance costs by a striking 40%.
