Product Description

Product Description

 

Introducing the NF98 Series, a pioneering advancement in nanofiltration technology. By integrating cutting-edge Thin Film Nanocomposite (TFN) technology, these membranes blend nano-level precision with ultra-thin hydrophilic coatings. This synergy results in incredible anti-fouling capabilities. The NF98 series triumphs over traditional TFC membranes by delivering a flux that is double that of conventional options while operating at a reduced pressure of at least 50%. Truly a compelling upgrade, these membranes are set to replace NF270, XC-N, DL, DK, and other standard TFC membranes, marking a new era in filtration innovation.

Key Features:

High Rejection Rate (over 98%):
Our membranes excel in providing high selectivity between monovalent and divalent ions. This facilitates the production of high-purity salt solutions, significantly minimizing the liquid volume for subsequent thermal treatments.
Anti-fouling and Chemical Resistant
The meticulously crafted membrane chemistry promises a durable and resilient element lifespan with exceptional anti-fouling characteristics.
Higher Flux
Capable of producing up to twice the flux compared to conventional TFC membranes, this enables increased water and resource retrieval alongside potential reductions in energy consumption.
High Removal of Organic Compounds
Achieves a high removal rate of organic compounds, effectively filtering out pesticides, herbicides, antibiotics, and THM precursors, among others.

 

Key Applications:

Industrial Minimum- and Zero-Liquid Discharge (MLD/ZLD)

Advanced industrial resource recovery and recycling initiatives

Water Softening

Chloralkali Processing

Landfill Leachate Treatment (de-coloring)

Farming Applications

In the agricultural sector, water is indispensable for ensuring optimal animal health and productivity. The quality of water, alongside its quantity, is a critical factor influencing the growth and performance of animals such as cattle, chickens, sheep, and pigs.
Farm water sources vary widely, including wells, civil water networks, and, to a lesser extent, rivers and other surface sources, each impacting the farm's water quality in unique ways.
With the exception of civil network water (often containing free chlorine), alternative sources typically harbor high levels of dissolved solids, suspended particulates, and pathogens. Reverse osmosis technology stands out as the most effective method to mitigate these adverse effects, necessitating advanced technological treatment to ensure water safety for animals.

Our Advantages

Proshare The Team's Revolutionary Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a new generation of reverse osmosis membranes, leveraging groundbreaking polymer interface nano-self-assembly technology. This innovation triumphs over the traditional limitations of reverse osmosis membrane development with two pivotal advancements:
Ultra-Thin Separation Layer Innovation: By masterfully applying polymer interface nanotechnology, the team has remarkably reduced the separation layer's thickness to an impressive degree-rendering it at least thrice thinner than the traditional polyamide thin films (once restricted to 100 nm). This monumental breakthrough elevates water flux, markedly boosting permeability.
Enhanced Performance and Durability: The strategic infusion of nanoparticles alongside specialized hydrophilic polymers has catalyzed groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
In stark contrast to traditional polyamide reverse osmosis membranes, Proshare's revolutionary innovation showcases breakthroughs in four crucial dimensions:
Self-Assembled Nanocomposite Films
The seamless integration of nano-scale precision control and nano-doping modification empowers the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This method effectively overcomes the constraints of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is expertly controlled, achieving a remarkable 3x reduction compared to traditional membranes. This culminates in >3x superior water flux and a significant 30% reduction in energy consumption.
Novel Polymer Materials with Unrivaled Chemical Stability
Transcending polyamide, the team harnesses the power of advanced hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These cutting-edge materials demonstrate exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (demonstrating stability across a 1-12 pH range).
Anti-Fouling Surface Engineering Mastery
The superhydrophilic surface, boasting a contact angle of less than 10° and fortified by nanoparticle reinforcement, dramatically reduces organic fouling propensity by 50%. This advancement extends chemical cleaning cycles from 3 to 6 months, slashing maintenance costs by 40%.
