State-of-the-art Sanitation technologies.
Innovative Recovery of reusable materials from wastewater.
Farming applications
Water plays a crucial role in ensuring the health and productivity of farm animals such as cattle, chickens, sheep, and pigs. While the quantity of water is important, its quality is equally critical in driving desired growth outcomes. Our solutions are designed to optimize both these aspects, ensuring that livestock thrive and perform at their best.
Farms can source water from various origins, including water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. Our innovative technologies ensure that regardless of the source, the water quality is maintained at optimal levels for agricultural success.
Apart from civil network water, which contains free chlorine, alternative water sources often harbor high concentrations of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology emerges as the most effective means of mitigating these adverse effects. At Proshare, we are committed to treating contaminated water on farms, thereby removing harmful substances and safeguarding animal health with the most advanced technological treatments.

Proshare Pioneering Innovations in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our expert team has ingeniously crafted a revolutionary new generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This advancement triumphs over the constraints of traditional membrane development through two pivotal breakthroughs:
Revolutionary Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, we've achieved a remarkable reduction in the separation layer's thickness, making it at least three times thinner than conventional polyamide thin films, which were previously limited to 100 nm. This significant innovation dramatically boosts water flux, leading to a remarkable enhancement in permeability.
Superior Enhanced Performance: By incorporating nanoparticles and specialized hydrophilic polymers, we have introduced groundbreaking improvements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
In comparison with traditional polyamide reverse osmosis membranes, Proshare's innovative approach showcases breakthroughs in four crucial aspects:
State-of-the-Art Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modification, we fabricate ultra-thin and highly ordered separation layers via polymer interface nanotechnology. This strategy overcomes the traditional polyamide membranes' limitations in thickness uniformity and material diversity.
Significantly Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, we precisely control the functional layer's thickness, achieving a threefold reduction compared to traditional membranes. This results in >3x higher water flux and an impressive 30% reduction in energy consumption.
Innovative Polymer Materials with Unparalleled Chemical Stability
Surpassing polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials provide exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and robust pH tolerance (stable across a wide pH range of 1-12).
Cutting-Edge Anti-Fouling Surface Engineering
