Farming applications
Water is a vital component for ensuring the health and optimal performance of farm animals such as cattle, chickens, sheep, and pigs. It is not just the availability but the quality of water that significantly impacts the desired growth and productivity of the animals.
Water used in farming can originate from diverse sources, including water wells, civil water networks, and to a lesser extent, from rivers and other superficial sources.
Apart from the chlorine-treated civil water networks, other water sources frequently contain high levels of dissolved and suspended solids as well as pathogens. Consequently, reverse osmosis technology has proven to be the most effective solution for mitigating the adverse effects of these contaminants on farm water supplies. It is imperative that such water undergoes technological treatment to diminish harmful substances, safeguarding animal health.
Proshare Tailor-made Our pioneering TFN special acid-resistant and high-pressure membranes are expertly crafted for Wastewater Treatment in Petrochemical/Refining industries, ensuring the ultimate achievement of Zero Liquid Discharge.
Proshare Tailor-made The TFN special acid-resistant and high-pressure membranes separation and concentration device is ingeniously designed for advanced wastewater treatment. It effectively handles ammonium sulphate desulphurisation, achieving wastewater concentration up to 40 times.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has revolutionized reverse osmosis membrane technology through pioneering polymer interface nano-self-assembly. This cutting-edge approach addresses traditional limitations with two transformative advancements:
Ultra-Thin Separation Layer: Leveraging polymer interface nanotechnology, we've achieved a remarkable reduction in separation layer thickness-now three times thinner than the conventional 100 nm polyamide thin films. This innovation markedly boosts water flux, dramatically elevating permeability and efficiency.
Enhanced Performance: By incorporating nanoparticles and specialized hydrophilic polymers, we've achieved groundbreaking improvements in hydrophilicity and performance, including superior anti-fouling capabilities, increased durability, and robust oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Through nano-scale precision and nano-doping, we craft ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This method surpasses the limitations of conventional polyamide membranes, notably in uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly, we precisely control functional layer thickness, achieving a 3x reduction relative to traditional membranes. This innovation delivers >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, we utilize advanced hydrophilic polymers and ceramic-organic hybrids. These cutting-edge materials show extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (stable across a 1-12 pH range).
Anti-Fouling Surface Engineering
