Farming applications

Water quality is crucial for ensuring optimal conditions for animal health-whether it be cattle, chickens, sheep, or pigs-and achieving peak productivity. Not only the volume but the purity of water significantly influences the desired growth and development of livestock.
On farms, water can originate from diverse sources such as water wells, civil water networks, and occasionally from rivers or other surface sources. Each source has unique characteristics impacting the water's suitability for agricultural use.
Excluding water from civil networks containing free chlorine, other water sources often have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective means of mitigating these negative effects. Contaminated farm water should undergo advanced treatment to eliminate harmful substances, ensuring the health and welfare of the animals.

Successful Cases Reference

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
The application of desalination membranes in the grand arena of international luxury cruise ships has been historically monopolized by leading global brands. As cruise ships traverse the world's oceans, the feed water quality experiences variations in salinity and temperature. These membranes must dynamically adapt to fluctuating conditions while maintaining a consistent water output to satisfy the rigorous demands of ocean-going vessels.
With PSI MEMBRANE Pro-HR-SW seawater desalination membranes, enjoy unparalleled performance in both desalination efficiency and consistent water production. The pristine water quality delivered by these membranes aligns perfectly with the high standards expected by luxury cruise ship operators.
This exceptional achievement has resulted in the adoption of these membranes on three additional cruise ships. Proshare's groundbreaking success positions it as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.

Our Advantages

Proshare Revolutionary Breakthrough by Our Team in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our innovative team has masterfully crafted a new generation of reverse osmosis membranes utilizing advanced polymer interface nano-self-assembly technology, overcoming the traditional barriers in reverse osmosis membrane development through two remarkable advancements:
Exceptionally Ultra-Thin Separation Layer: Leveraging cutting-edge polymer interface nanotechnology, our team has achieved a remarkable feat, reducing the separation layer's thickness to an astonishingly thin profile-at least three times thinner than the standard polyamide thin film (previously restricted to 100 nm). This groundbreaking innovation dramatically enhances water flux, yielding an impressive improvement in permeability.
Unparalleled Performance Enhancement: Through the infusion of nanoparticles and meticulously formulated hydrophilic polymers, we have pioneered transformative advancements in the membrane's hydrophilicity, anti-fouling capability, longevity, and oxidation resistance.
When juxtaposed with traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation achieves significant breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films with Precision Engineering
By uniting nano-scale precision control and nano-doping modification, we craft ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This sophisticated approach surpasses the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux Coupled with Remarkable Energy Efficiency
Through meticulous refinement of the layer-by-layer self-assembly process, the functional layer thickness is precisely calibrated, resulting in a 3x reduction compared to standard membranes. This leads to >3x amplified water flux and a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials Boasting Superior Chemical Stability
Transitioning beyond polyamide, our team adopts advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials demonstrate exceptional oxidation resistance (capable of enduring 10 ppm chlorine exposure) and impressive pH resilience (maintaining stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) augmented with nanoparticle reinforcement notably diminishes organic fouling propensity by 50%, extending the chemical cleaning cycles from 3 months to an astounding 6 months, and significantly reducing maintenance costs by 40%.
