• Extensive Cleaning pH (1-13) Range:Delivers superior cleaning efficiency, along with robustness and durability, thanks to its broad cleaning pH range and exceptional chemical tolerance.

Key Applications:
Ideal for softening, producing ultra-pure water, and facilitating water reuse
across industries such as pharmaceuticals, electronics, power, petrochemical, refinery, food & beverage, and municipal sectors, etc.

A common issue with RO membrane elements is fouling. While fouling doesn't alter the structure of RO membrane elements, the buildup of foulants on the membrane surface can drastically impair its performance.
effectively prevents fouling through the application of a patented hydrophilic coating on the membrane surface, ensuring long-term stable operation. This prevention of fouling reduces the frequency of cleaning, ultimately leading to lower operational expenses (OPEX) at water treatment facilities.
addresses the needs of treating urban sewage water for industrial applications.

Farming applications

Water is crucial to ensure the health of farm animals (e.g., cattle, chickens, sheep, pigs) and optimize their productive performance. Beyond quantity, the quality of water significantly impacts the desired growth of the animals.
In farming, water may originate from various sources such as water wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Excluding civil water networks, which contain free chlorine, other sources often have high levels of dissolved solids, suspended particles, and pathogens. Reverse osmosis technology has proven to be the most effective in mitigating these adverse effects. Contaminated farm water requires technological treatment to reduce harmful substances that could impact animal health.

Our Advantages

Proshare Pioneering Innovations in Advanced Reverse Osmosis Membrane Technology
Proshare Our dedicated team has revolutionized the development of reverse osmosis membranes by introducing a cutting-edge generation grounded in polymer interface nano-self-assembly technology. This landmark achievement surmounts the traditional limitations, delivering two transformative advancements:
Ultra-Thin Separation Layer Mastery: Leveraging breakthrough polymer interface nanotechnology, our team has reduced the separation layer to a remarkable thickness, making it up to three times thinner than conventional polyamide thin films (previously constrained to 100 nm). This innovation dramatically boosts water flux and significantly optimizes permeability for unparalleled performance.
Enhanced Performance Unleashed: By infusing nanoparticles and specialized hydrophilic polymers, we've achieved monumental strides in enhancing the membrane's hydrophilicity, anti-fouling capabilities, longevity, and resistance to oxidation.
In comparison to conventional polyamide reverse osmosis membranes, Proshare's pioneering innovation showcases breakthroughs in four strategic areas:
Self-Assembled Nanocomposite Films Craftsmanship
Through nano-scale precision control and innovative nano-doping modification, we seamlessly create ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This avant-garde approach transcends the constraints of traditional polyamide membranes in maintaining thickness uniformity and material diversity.

Enhanced Water Flux and Energy Efficiency Excellence
By perfecting the layer-by-layer self-assembly process, we achieve precise control of functional layer thickness, achieving a threefold reduction compared to traditional membranes. This advancement translates to >3x increased water flux and 30% reduced energy consumption,setting new standards for eco-efficiency.
Innovative Polymer Materials with Unparalleled Chemical Stability
Advancing beyond the polyamide norm, we utilize cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials offer outstanding resistance to oxidation (withstanding exposure to 10 ppm chlorine) and excellent pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering Revolution
The ultra-hydrophilic surface (contact angle <10°) coupled with nanoparticle reinforcement dramatically reduces organic fouling by 50%. This progression extends the duration of chemical cleaning cycles from 3 months to 6 months, effectively slashing maintenance costs by 40% and boosting operational efficiency.
