Farming applications
Water is indispensable for ensuring the optimal health and productivity of farm animals, such as cattle, chickens, sheep, and pigs. Not only does the quantity of water matter, but its quality is just as critical to achieve desired growth and performance in animals.
Water for farming purposes might originate from various sources, including water wells, civil water networks, and to a lesser extent, rivers, and other superficial sources.
Excluding water from civil networks that contain free chlorine, other sources generally possess high levels of dissolved and suspended solids and pathogens. Hence, reverse osmosis technology has proven to be the most efficient method to mitigate the detrimental effects of contaminated water. Farms should employ technological treatment to minimize substances that could be harmful to animals.

Proshare Breakthrough Achievements in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a revolutionary generation of reverse osmosis membranes, utilizing state-of-the-art polymer interface nano-self-assembly technology. This breakthrough triumphantly addresses the constraints of traditional development through two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Through the innovative application of polymer interface nanotechnology, we have achieved an unprecedented reduction in the thickness of the separation layer, making it at least three times thinner than the conventional polyamide thin film (previously capped at 100 nm). This significant breakthrough exponentially boosts water flux, resulting in a remarkable enhancement in permeability.
Augmented Performance and Durability: By leveraging nanoparticles and advanced hydrophilic polymers, we have introduced transformative advancements in the membrane's hydrophilicity, anti-fouling capabilities, long-lasting durability, and robust oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases groundbreaking achievements across four critical dimensions:
Innovative Self-Assembled Nanocomposite Films
Our incorporation of nano-scale precision control and nano-doping modification crafts ultra-thin, precisely ordered separation layers through advanced polymer interface nanotechnology. This methodology transcends the limitations faced by conventional polyamide membranes concerning thickness uniformity and material versatility.
Optimized Water Flux and Superior Energy Efficiency
By perfecting the layer-by-layer self-assembly process, we meticulously control the functional layer's thickness, achieving a remarkable 3x reduction compared to standard membranes. This innovation leads to an impressive >3x increase in water flux coupled with a 30% reduction in energy consumption.
Novel Polymer Materials with Exceptional Chemical Stability
Surpassing traditional polyamide, we utilize cutting-edge hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These pioneering materials exhibit outstanding oxidation resistance (withstanding exposure to up to 10 ppm chlorine) and superior pH tolerance (stable across a broad 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface (with a contact angle of less than 10°), reinforced with nanoparticles, minimizes the tendency for organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 months to 6 months, substantially reducing maintenance costs by 40%.
Our commitment to quality, health, and environmental sustainability is exemplified through our prestigious certifications, including the Health & Safety Management System Certificate, Environmental Management System Certificate, and the renowned ISO9001 Quality System Certificate.
At the forefront of innovation, we proudly hold invention patents for our cutting-edge membrane production and breakthrough multi-layer RO membrane technology.
