Farming Applications
In farming, water quality is key to ensuring optimal health and productivity of livestock, including cattle, chickens, sheep, and pigs. Beyond mere quantity, the quality of water directly impacts the animals' growth and performance, making it essential to maintain high standards of purity and safety.
Farm water can originate from various sources, such as water wells, municipal water networks, and occasionally rivers and other surface sources. Each source requires careful consideration to ensure it meets the requisite purity standards for animal consumption.
With the exception of municipal water networks (which contain free chlorine), most other sources are laden with dissolved and suspended solids and potential pathogens. Reverse osmosis technology proves to be the most efficient at mitigating these contaminants. It's imperative that contaminated farm water undergoes advanced technological treatment to eliminate harmful substances and protect the well-being of livestock.

Proshare Innovation Suzhou Co., Ltd. A Leap Forward: Proshare Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Innovation Suzhou Co., Ltd. Our pioneering Proshare team has ingeniously crafted a new era of reverse osmosis membranes, rooted in the avant-garde polymer interface nano-self-assembly technology. This innovation transcends the conventional boundaries of traditional reverse osmosis membrane development through two pivotal strides:
Revolutionizing with an Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has remarkably minimized the separation layer's thickness, achieving a threefold reduction compared to the standard polyamide thin film (formerly restrained at 100 nm). This formidable advancement propels water flux to new heights, heralding significant strides in permeability.
Performance Like Never Before: Enhanced and Superior: By incorporating nanoparticles and uniquely tailored hydrophilic polymers, we have achieved unprecedented advancements in the membrane's hydrophilicity, anti-fouling prowess, and its fortitude against wear and oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare Innovation Suzhou Co., Ltd.unveils remarkable breakthroughs across four pivotal dimensions:
Groundbreaking Self-Assembled Nanocomposite Films
The fusion of nano-scale precision manipulation and nano-doping modification fosters the emergence of ultra-thin, impeccably ordered separation layers via polymer interface nanotechnology. This cutting-edge method overcomes the traditional constraints of polyamide membranes in terms of uniform thickness and material versatility.
Unparalleled Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is precisely managed, achieving an astounding 3x reduction compared to traditional membranes. This breakthrough results in over 3x the water flux and a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials with Extraordinary Chemical Stability
Surpassing the polyamide frontier, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) along with ceramic-organic hybrids. These materials exhibit remarkable resistance to oxidation (withstanding exposure to 10 ppm chlorine) and remarkable pH stability (retaining stability across a pH range of 1 to 12).
Advanced Anti-Fouling Surface Engineering
