Industry Applications
Proshare Proshare has garnered prestigious expertise by presenting its cutting-edge technical solutions to the industrial sector. Here, absolutely pure water is indispensable for various industrial processes, including wastewater treatment, resource recycling, and reuse.
We are engaged in major industry sectors such as petrochemical, mining, lithium extraction from salt lakes, lithium iron phosphate & lithium battery recycling, semiconductors, seawater desalination, reclaimed water, leachate treatment, synthetic biology, copper foil production, pharmaceutical, and power industries.
Our expertise extends to steam boiler feeding, food & beverages (mineral water bottling, soft drinks, juices), painting lines, dairies, ice creams, laundries, hospitals, textile, mechanical industries, and steel companies.
Hospitality/Seawater and Brackish Water Desalination Applications
Boasting extensive experience in desalination technology, Proshare has adeptly applied this knowledge to the realm of water desalination for civil use in hotels and tourist resorts. Freshwater supply is vital for these infrastructures, and reverse osmosis (R.O.) sea or brackish water desalination offers an effective solution to meet the escalating water demands of burgeoning tourist regions.
Farming applications
Water plays a crucial role in ensuring the health of livestock (e.g., cattle, chickens, sheep, pigs) and in achieving optimal productivity. The growth of animals depends not only on water quantity but also significantly on water quality.
Water for farming originates from diverse sources, such as water wells, municipal water networks, and, occasionally, rivers and other surface sources.
Excluding water from municipal networks (which contains free chlorine), other sources typically possess high concentrations of dissolved and suspended solids and pathogens. Thus, reverse osmosis technology has proven to be the most effective means of mitigating these adverse effects. Contaminated farm water must undergo technological treatment to diminish harmful substances detrimental to animal health.
Municipal and Civil use
At Proshare, we deliver innovative, scalable solutions for efficient and sustainable wastewater and effluent treatment. Our diverse array of patented technologies, alongside national-level experts and scientific research institutions, ensures peace of mind for municipalities adhering to stringent health and environmental standards.

Proshare Groundbreaking Advancements in Revolutionary Reverse Osmosis Membrane Technology
Proshare leverages pioneering polymer interface nano-self-assembly technology in crafting the next generation of reverse osmosis membranes, shattering the constraints of traditional membrane development through two monumental advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, Proshare's team has achieved a remarkable reduction in the separation layer thickness-now at least three times thinner than standard polyamide thin films (formerly confined to 100 nm). This transformative breakthrough catapults water flux to new heights, markedly enhancing permeability.
Elevated Performance: The strategic incorporation of nanoparticles alongside specialized hydrophilic polymers has ushered in groundbreaking advancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting new benchmarks for membrane performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovative approach signifies breakthroughs in four essential dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we craft ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This pioneering method transcends the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
With meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is expertly controlled, achieving a threefold reduction compared to traditional membranes. This precision results in more than 3x increased water flux and a 30% reduction in energy consumption.
Revolutionary Polymer Materials with Superior Chemical Stability
Surpassing polyamide, the team employs advanced hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These cutting-edge materials demonstrate extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability in a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
