Our expertise extends to applications such as steam boiler feed, food & beverages (including mineral water bottling, soft drinks, and juices), painting lines, dairy production, ice cream manufacturing, laundries, hospitals, textiles, mechanical industries, and steel companies.
Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology has been effectively utilized in water desalination for civil uses in hotels and touristic resorts. A reliable supply of fresh water is vital for such establishments, and our R.O. seawater or brackish water desalination solutions are tailored to meet the growing water demands of rapidly expanding touristic regions and infrastructure.
Farming applications
Water is crucial for ensuring the health and optimal performance of farm animals such as cattle, chickens, sheep, and pigs. The quality of water significantly impacts their growth, not just the quantity.
Farm water can be sourced from various origins, including water wells, public water networks, and, to a lesser extent, rivers and other surface sources.
Apart from water from public networks, which contains free chlorine, other sources often have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology has proven to be highly effective in mitigating these adverse effects, and contaminated farm water should undergo treatment to eliminate harmful substances for the animals.

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the realm of desalination membranes on high-end international luxury cruise ships has been dominated by a select few global brands. The journey of a cruise ship brings fluctuating water quality, with varying salinity and temperature. This demands that the membranes not only adapt seamlessly to these changing conditions but also maintain a consistent and reliable water production to meet the requirements of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes shone with exceptional performance in both desalination efficiency and reliable water output. The produced water quality effortlessly met the rigorous standards demanded by luxury cruise ships, cementing Proshare's reputation for excellence.
Proshare's triumph in this field led to the replacement of membranes across three more cruise ships, making it the first national brand to secure international luxury cruise ship orders for desalination RO membranes. This remarkable achievement highlights Proshare's pioneering success on the global stage.

Proshare Pioneering Breakthrough in Advanced Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously crafted an avant-garde generation of reverse osmosis membranes, leveraging polymer interface nano-self-assembly technology to transcend the norms of conventional membrane development. This is achieved through two monumental innovations:
Ultra-Thin Separation Layer Mastery: Utilizing cutting-edge polymer interface nanotechnology, our experts have remarkably diminished the separation layer's thickness to one-third of conventional polyamide thin films (historically constrained to 100 nm). This significant breakthrough exponentially enhances water flux, marking a profound leap in permeability.
Superior Performance Enhancement: By incorporating nanoparticles and pioneering hydrophilic polymers, we've made revolutionary strides in enhancing the membrane's hydrophilicity, anti-fouling properties, resilience, and resistance to oxidation.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs in four vital areas:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control with nano-doping modifications, we craft ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This technique overcomes the hurdles of conventional polyamide membranes concerning thickness uniformity and material diversity.
Enhanced Water Flux and Energy Optimization
Optimizing the layer-by-layer self-assembly process allows for precise control of functional layer thickness, achieving a remarkable 3x reduction compared to conventional membranes. This innovation results in >3x greater water flux and 30% lower energy demands.
Revolutionary Polymer Materials with Unprecedented Chemical Stability
Surpassing polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (enduring 10 ppm chlorine exposure) and pH resilience (remaining stable across a 1-12 pH spectrum).
Cutting-Edge Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (with a contact angle <10°) fortified by nanoparticle enhancement, significantly reduces the organic fouling propensity by 50%. This innovation extends chemical cleaning cycles from 3 months to 6 months, cutting maintenance costs by 40%.
Our company proudly holds essential certifications including the Health & Safety Management System Certificate, the Environmental Management System Certificate, and the esteemed ISO9001 Quality System Certificate. Each of these accreditations reflects our unwavering commitment to quality, safety, and environmental responsibility in every aspect of our operations.
