Farming Applications: Ensuring Optimal Animal Health

Water plays a pivotal role in maintaining animal health (e.g., cattle, chickens, sheep, pigs) and is critical for attaining peak productive performance. Beyond quantity, water quality is essential to influence desirable growth outcomes for animals.
Farm water can be sourced from various origins, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Except for water from civil networks (which contains free chlorine), other sources often have high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be highly effective in mitigating these adverse effects. It is essential to treat contaminated farm water to remove harmful substances and protect animal health.

Our Advantages

Proshare Team's Remarkable Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team pioneeringly crafted a revolutionary generation of reverse osmosis membranes utilizing polymer interface nano-self-assembly technology, shattering the constraints of conventional membrane development through two pivotal innovations:
Revolutionary Ultra-Thin Separation Layer: Through the application of polymer interface nanotechnology, the team dramatically minimized the thickness of the separation layer, achieving a thickness at least three times thinner than the conventional polyamide thin film, which was previously constrained to 100 nm. This groundbreaking advancement tremendously boosts water flux, resulting in a significant surge in permeability.
Unmatched Enhanced Performance: The incorporation of nanoparticles and specialized hydrophilic polymers has catalyzed unprecedented advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation marks breakthroughs in four crucial areas:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control and nano-doping modification facilitates the formation of ultra-thin, meticulously ordered separation layers via advanced polymer interface nanotechnology. This pioneering technique triumphs over the traditional polyamide membranes' limitations concerning thickness uniformity and material diversity.
Elevated Water Flux and Superior Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the precise control of the functional layer thickness is achieved, leading to a threefold reduction compared to conventional membranes. This culminates in an impressive >3x Increase in Water Flux and a remarkable 30% Reduction in Energy Consumption.
Revolutionary Novel Polymer Materials with Unrivaled Chemical Stability
Surpassing traditional polyamide, the team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and innovative ceramic-organic hybrids. These pioneering materials reveal outstanding oxidation resistance (withstanding 10 ppm chlorine exposure) and pH stability (enduring within a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
The exceptionally superhydrophilic surface (with a contact angle of less than 10°) coupled with nanoparticle reinforcement remarkably diminishes organic fouling potential by 50%, thereby extending the chemical cleaning cycles from 3 months to an impressive 6 months, while also reducing maintenance expenses by a substantial 40%.
