Farming applications
Water is crucial for ensuring the health and optimum performance of livestock, such as cattle, chickens, sheep, and pigs. However, it is not only the quantity of water that impacts animal growth but also the quality. We recognize the significance of providing high-quality water to achieve the best results in animal productivity.
Farms source their water from various origins, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources. Our solutions are designed to manage and optimize these diverse water supplies, ensuring they meet the highest standards for farm use.
Excluding water from civil networks, which contains free chlorine, other sources typically exhibit high concentrations of dissolved and suspended solids, as well as pathogens. Reverse osmosis technology has proven to be the most effective method to mitigate these negative effects. Contaminated farm water requires advanced technological treatment to reduce harmful substances, safeguarding animal health and enhancing growth outcomes.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team has crafted a pioneering generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology, surmounting traditional developmental constraints with two groundbreaking advancements:
Ultra-Thin Separation Layer: Through the advanced application of polymer interface nanotechnology, our team has achieved an incredible reduction in the separation layer's thickness, now thrice thinner than the conventional polyamide thin film, which was limited to 100 nm. This remarkable leap substantially boosts water flux, leading to exceptional improvements in permeability and efficiency.
Enhanced Performance: With the infusion of nanoparticles and specially designed hydrophilic polymers, we have realized transformative progress in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation, setting new standards in performance and resilience.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases significant advances across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Through nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This strategy triumphs over the thickness uniformity and material diversity barriers of conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
With an optimized layer-by-layer self-assembly process, we have precisely regulated the functional layer's thickness, realizing a threefold reduction compared to traditional membranes. This process yields over three times the water flux and 30% reduced energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Advancing beyond polyamide, the use of sophisticated hydrophilic polymers like modified polysulfones and ceramic-organic hybrids demonstrates exceptional resilience to oxidation (withstanding exposure to 10 ppm chlorine) and impressive pH stability (resilient within a 1-12 pH range).
Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface (with a contact angle less than 10°) coupled with nanoparticle reinforcement substantially diminishes organic fouling potential by 50%, extending chemical cleaning intervals from three to six months, while slashing maintenance costs by 40%.
Our unwavering commitment to excellence is underscored by our prestigious certifications that speak volumes about our dedication to quality and sustainability. These include the Health & Safety Management System Certificate, certifying our commitment to a safe and healthy work environment; the Environmental Management System Certificate, which highlights our proactive measures in preserving our planet; and the renowned ISO9001 Quality System Certificate, reflecting our adherence to the highest standards of quality management.
