Farming Applications

Water plays a critical role in ensuring the well-being and optimal growth performance of farm animals such as cattle, chickens, sheep, and pigs. It's not just the quantity but the quality of water that significantly impacts animal health and productivity.
Farm water sources are diverse, ranging from water wells and civil water networks to rivers and other superficial bodies. The quality of these sources can vary greatly, impacting overall farm operations.
Beyond civil network water (which contains free chlorine), other sources often harbor high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be the most effective method for mitigating these negative effects. It is vital that farm water undergoes technological treatment to remove harmful substances and ensure animal health and productivity.

Our Advantages

Proshare Team's Remarkable Leap in Next-Gen Reverse Osmosis Membrane Innovation
Proshare The team has ingeniously pioneered a new era of reverse osmosis membranes using cutting-edge polymer interface nano-self-assembly technology, revolutionizing traditional membrane constraints with two pivotal breakthroughs:
Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, the team has successfully minimized the separation layer thickness to a groundbreaking level-at least three times thinner than conventional polyamide thin films, previously restricted to 100 nm. This transformative advancement notably amplifies water flux, offering a monumental leap in permeability.
Boosted Performance: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has led to revolutionary progress in the membrane's hydrophilicity, anti-fouling prowess, durability, and resistance to oxidation.
In comparison to standard polyamide reverse osmosis membranes, Proshare's innovation marks significant breakthroughs across four vital dimensions:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification facilitates the formation of ultra-thin, precisely ordered separation layers via polymer interface nanotechnology, effectively addressing the limitations in thickness consistency and material variety inherent to traditional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is expertly regulated to achieve a remarkable 3x reduction compared to conventional membranes, resulting in >3x increased water flux and 30% decreased energy consumption.
Innovative Polymer Materials with Outstanding Chemical Resistance
Advancing beyond polyamide, the team deploys state-of-the-art hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids, which demonstrate remarkable resistance to oxidation (capable of withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The superhydrophilic surface, with a contact angle less than 10°, coupled with nanoparticle fortification, substantially diminishes organic fouling by 50%, extending chemical cleaning intervals from an industry norm of 3 months to an impressive 6 months, and reducing maintenance expenses by 40%.
