Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination has been adeptly applied in the realm of water desalination for civil applications within hotels and touristic resorts. Freshwater availability is a cornerstone for such establishments, and our R.O. seawater or brackish water desalination solutions stand as exceptional alternatives to meet the burgeoning demands of rapidly growing tourist areas.
Farming applications
Water is the lifeline to ensuring optimal health and peak performance in farm animals such as cattle, chickens, sheep, and pigs. Both the quantity and superior quality of water are pivotal to achieving desired growth and productivity in animals.
On farms, water sources are diverse, originating from wells, civil water networks, and, to a lesser extent, rivers and other surface sources.
Excluding the civil network water (often containing free chlorine), other sources typically harbor high levels of dissolved solids, suspended particles, and pathogens. Consequently, reverse osmosis technology emerges as the most proficient method to mitigate these adverse effects. Contaminated farm water must undergo technological treatment to diminish harmful substances affecting animal health.

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the use of desalination membranes on luxury international cruise ships has been the domain of select global brands. As cruise ships traverse diverse waters, the quality of feed water-including salinity and temperature-varies, necessitating membranes that can adapt and consistently deliver stable water production. This adaptability is crucial to fulfilling the demanding water needs of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes showcased extraordinary proficiency, excelling in both the desalination rate and consistent water production. The output water quality from these membranes adhered to the rigorous standards required by the cruise ships.
This outstanding achievement paved the way for the replacement of desalination membranes on an additional three cruise ships. Proshare's triumph in this initiative marks a significant milestone, establishing it as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.
A Complete Water Treatment Plant for Generating Ultra-pure Water in Semiconductor Industry

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has ingeniously pioneered a revolutionary new generation of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, we have skillfully overcome the constraints of conventional membrane development with two pivotal breakthroughs:
Ultra-Thin Separation Layer: Leveraging advanced polymer interface nanotechnology, our team has remarkably thinned the separation layer to an extraordinary extent, achieving at least one-third the thickness of traditional polyamide thin films (previously confined to 100 nm). This exceptional innovation dramatically amplifies water flux, resulting in a substantial boost in permeability.
Enhanced Performance: Through the integration of nanoparticles and uniquely engineered hydrophilic polymers, we have ushered in transformative advancements including superior hydrophilicity, enhanced anti-fouling capabilities, unmatched durability, and robust oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation shines with breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
By skillfully melding nanoscale precision control with nano-doping modification, we craft ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This novel approach surpasses conventional polyamide membranes, offering unparalleled improvements in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through precise optimization of our layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, resulting in an impressive 3x reduction compared to traditional membranes. This achievement leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Transcending the limitations of polyamide, we employ sophisticated hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These advanced materials boast exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable across a pH range of 1-12).
