Water quality is vital for ensuring optimal animal health and productivity, whether it's cattle, chickens, sheep, or pigs. The quantity and quality of water significantly influence animals' growth and performance.
Farm water sources vary, originating from wells, civil water networks, and occasionally rivers or surface bodies.
Except for water from civil networks with free chlorine, other sources often contain high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven the most effective in mitigating these negative impacts. Thus, farm water, particularly contaminated sources, should undergo treatment to eliminate harmful substances, ensuring safety for animals.

Proshare Pioneering Breakthrough in Next-Gen Reverse Osmosis Membrane Technology
Proshare Our innovative team has ingeniously crafted a revolutionary generation of reverse osmosis membranes using cutting-edge polymer interface nano-self-assembly technology. This advancement triumphs over the constraints faced in traditional reverse osmosis membrane development through two monumental achievements:
Revolutionary Ultra-Thin Separation LayerBy harnessing the prowess of polymer interface nanotechnology, our team has impressively reduced the separation layer's thickness to a remarkable extent-at least threefold thinner than conventional polyamide thin films (historically restricted to 100 nm). This groundbreaking feat dramatically boosts water flux and achieves a notable enhancement in permeability.
Superior Performance EnhancementThe infusion of nanoparticles and state-of-the-art hydrophilic polymers has propelled unprecedented advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
When compared with traditional polyamide reverse osmosis membranes, Proshareis at the forefront, showcasing remarkable breakthroughs across four crucial dimensions:
Innovative Self-Assembled Nanocomposite Films
Through meticulous nano-scale precision control and nano-doping modification, we produce ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This strategy overcomes the challenges of conventional polyamide membranes concerning thickness uniformity and material diversification.
Boosted Water Flux and Enhanced Energy Efficiency
By perfecting 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 over threefold higher water flux coupled with a 30% decrease in energy consumption.
Innovative Polymer Materials Featuring Superior Chemical Stability
Venturing beyond polyamide, our team employs advanced hydrophilic polymers (such as modified polysulfones) alongside ceramic-organic hybrids. These materials demonstrate exceptional resistance to oxidation (withstanding up to 10 ppm chlorine exposure) and broad pH tolerance (remaining stable across a pH range of 1-12).
Cutting-Edge Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (with a contact angle less than 10°) combined with nanoparticle reinforcement slashes organic fouling propensity by 50%, extending chemical cleaning cycles from three to six months and slashing maintenance costs by 40%
