Hospitality/Seawater and Brackish Water Desalination Applications
Leveraging Proshare's vast experience in desalination technology, we extend our proficiency to provide water desalination solutions tailored for civil applications, particularly in hotels and touristic resorts. Freshwater supply is a critical necessity for these infrastructures. Hence, our Reverse Osmosis (R.O.) sea water or brackish water desalination offers a robust alternative solution capable of fulfilling the growing capacity requirements and surging water demands of these rapidly expanding tourist hubs.
Farming applications
In farming, water is indispensable not only to ensure animal health-spanning cattle, chickens, sheep, and pigs-but also to maximize their productive performance. The quality of water is as crucial as its quantity, impacting the desired growth and well-being of animals.
Farm water sources are diverse, stemming from water wells, civil water networks, and, to a lesser extent, rivers and other surface sources. It's imperative to manage these resources effectively for optimal farm operations.
Excluding water sourced from civil networks, which typically contains free chlorine, other sources often present high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most efficient method to mitigate such negative effects. Therefore, contaminated farm water must undergo rigorous technological treatment to diminish harmful substances, safeguarding animal health.

Proshare Trailblazing Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare has achieved a revolutionary advancement in the realm of reverse osmosis membranes. Utilizing the groundbreaking polymer interface nano-self-assembly technology, our team has successfully overcome the constraints traditionally faced in membrane development through two groundbreaking innovations:
Revolutionary Ultra-Thin Separation Layer: By adeptly employing polymer interface nanotechnology, the team has impressively refined the separation layer's thickness, making it at least thrice as thin as the conventional polyamide thin film (which was previously capped at 100 nm). This pioneering advancement not only amplifies water flux but also significantly boosts permeability, achieving unparalleled performance.
Enhanced Operational Performance: Integrating cutting-edge nanoparticles and uniquely formulated hydrophilic polymers, our membranes achieve remarkable improvements in hydrophilicity, anti-fouling capacity, longevity, and oxidation resilience.
When compared to conventional polyamide reverse osmosis membranes, Proshare's innovation marks significant advancements across four decisive fronts:
State-of-the-Art Self-Assembled Nanocomposite Films
By intertwining nano-scale precision control with nano-doping modifications, we craft ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This sophisticated method surpasses conventional polyamide membranes' constraints concerning thickness consistency and material diversity.
Exemplary Water Flux and Energy Efficiency
Through the strategic optimization of the layer-by-layer self-assembly process, the thickness of the functional layer is meticulously regulated, culminating in a 3x reduction compared to traditional membranes. This advancement culminates in >3x superior water flux alongside a 30% decrease in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
Transitioning beyond polyamide, our team employs avant-garde hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These remarkable materials offer exceptional resilience to oxidation (withstanding up to 10 ppm chlorine exposure) and robust pH tolerance (maintaining stability across a pH range of 1-12).
Cutting-Edge Anti-Fouling Surface Engineering
