Farming applications

Water is the lifeblood of agricultural success, playing a critical role in ensuring the health and productivity of livestock, such as cattle, chickens, sheep, and pigs. However, the quality of water is as vital as its quantity to foster the optimal growth and performance of these animals.
In farming, water is sourced from various origins including water wells, municipal water networks, and occasionally from rivers and other surface sources. Each source contributes uniquely to the farm's water needs.
Excluding municipal water (which contains free chlorine), alternative sources typically feature elevated levels of dissolved and suspended solids, as well as pathogens. Therefore, deploying reverse osmosis technology has proven to be the most effective method to mitigate the adverse effects of contaminants in farm water. This technological treatment is crucial to eliminate harmful substances, ensuring the water is safe for animal consumption.

Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team at Proshare has ingeniously crafted a revolutionary generation of reverse osmosis membranes, utilizing advanced polymer interface nano-self-assembly technology. This state-of-the-art innovation shatters the constraints of traditional reverse osmosis membranes with two pivotal advancements:
Ultra-Thin Separation Layer: Leveraging the cutting-edge polymer interface nanotechnology, our team has remarkably minimized the thickness of the separation layer, achieving a thickness reduction of at least three times compared to conventional polyamide thin films, which were previously limited to 100 nm. This monumental breakthrough not only amplifies water flux but also considerably boosts permeability, setting a new standard in water treatment.
Enhanced Performance: The strategic infusion of nanoparticles alongside specialized hydrophilic polymers has led to unprecedented strides in the membrane's hydrophilicity. Furthermore, it significantly enhances anti-fouling capabilities, durability, and offers remarkable oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation manifests breakthroughs across four pivotal aspects:
Self-Assembled Nanocomposite Films
Employing nano-scale precision control paired with nano-doping modification, we craft ultra-thin, highly ordered separation layers through advanced polymer interface nanotechnology. This cutting-edge approach transcends the limitations of traditional polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, achieving a remarkable 3x reduction when compared to traditional membranes. This innovation culminates in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Beyond the confines of polyamide, our team has embraced cutting-edge hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials exhibit exemplary oxidation resistance (capable of withstanding up to 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a wide pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, boasting a contact angle of less than 10°, is further reinforced with nanoparticles. This innovation reduces organic fouling propensity by 50%, thereby extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by a substantial 40%.
