Application Of Nanofiltration Ceramic Membrane Element

 
Chemical industry (membrane technology in the chemical industry)

a. Application in catalyst recovery in the petrochemical industry
In petrochemical and chemical production, the application of the catalyst is very extensive, and it is generally necessary to separate the product and the catalyst after the reaction. Ceramic nanofiltration membrane has good heat resistance, chemical solvent resistance, and good mechanical strength. It adopts cross-flow filtration method in catalytic reaction solid-liquid separation and has the advantages of high-temperature resistance, acid and alkali resistance, solvent resistance, etc. The coupling can fully improve the efficiency of the reactor, high separation precision, and can separate the nano-scale catalyst.

b. Application in brine purification in the field of the chlor-alkali chemical industry
Ceramic nanofiltration membrane has excellent performance such as pollution resistance and long life and is widely used in the field of chlor-alkali chemical industry. Using efficient "cross-flow" filtration, it is difficult to achieve results and advantages with other refining and filtration technologies.

Fine separation of medicine

Compared with traditional organic membranes, ceramic composite nanofiltration membranes have the unique advantages of high separation precision, guaranteed filtrate quality, high flux filtration, high product yield, low wastewater, low cleaning frequency and no need for additives. It can realize desalting and pre-concentration of target products and has been successfully applied to biological enterprises such as glutamic acid, citric acid, itaconic acid, and vitamin C.

Environmental water treatment (water filtration membrane)

The integrated process with ceramic membrane + organic membrane as the core is widely used in: oily water filtration system, metallurgical wastewater treatment, chemical wastewater treatment, paper mill wastewater treatment, large-scale pure water and ultrapure water preparation, zero discharge of power plant brine.

Gas purification

The integrated process technology with ceramic nanofiltration membrane as the core has the unique advantages of high separation precision, short process, acid and alkali resistance, high-temperature resistance and pollution resistance. It is widely used in industrial flue gas desulfurization, blast furnace solid-gas separation and automobile exhaust gas treatment. Wait.

New materials field

The ceramic nanofiltration membrane can effectively remove impurity ions in the slurry and efficiently prepare ultrafine ultra-pure nano-powder. At present, it has been applied to the purification of nano-powders such as nano-catalysts and ultra-pure non-ferrous metals. It can also be used in the purification process of nano-materials such as lithium batteries and graphene so that the impurity components in the production process can be removed in time, which is beneficial to the improvement of product yield.

Structure of an RO Membrane

An RO membrane is composed of several layers, each with a specific function. The most important layer is the thin-film composite, which is responsible for the actual filtration process. This layer is typically made of polyamide and is only a few micrometers thick.

Surrounding the thin-film composite layer are several other layers that provide structural support and protect the membrane from damage. These include a polysulfone layer, a micro-porous support layer, and a non-woven fabric support layer.

The operation of an RO membrane is based on the principle of osmosis, a natural process in which water molecules move from an area of low solute concentration to an area of high solute concentration. In the RO process, however, this natural flow is reversed through the application of pressure.

When pressurized water is applied to one side of the RO membrane, water molecules are forced through the membrane, while larger molecules and ions are left behind. The result is purified water on one side of the membrane and a concentrated brine solution on the other.

Q: What membrane is used in nanofiltration?

A: Nanofiltration is a separation process characterized by organic, thin-film composite membranes with a pore size range of 0.1 to 10nm. Unlike reverse osmosis (RO) membranes, which reject all solutes, NF membranes can operate at lower pressures and offer selective solute rejection based on both size and charge.

Q: What is the difference between NF membrane and RO membrane?

A: NF removes harmful contaminates, such as pesticide compounds and organic macromolecules, while retaining minerals that RO would otherwise remove. Nanofiltration membranes are capable of removing larger divalent ions such as calcium sulfate, while allowing smaller monovalent ions such as sodium chloride to pass through.

Q: What is the ideal temperature for a reverse osmosis membrane?

A: All reverse osmosis membrane elements and systems are rated at 77º Fahrenheit (25º Celsius).

Q: Does high temperature increase osmosis?

A: Osmosis can be enhanced by operating at increased temperatures. Water flux and power density is increased by >110 % with 50 °C feed solution. Achieving a warm active membrane layer is the key to effectively using heat.

Q: What is the lifespan of the RO membrane?

A: 2-5 years
How Long Does an RO Membrane Last? The lifespan of the membrane can vary depending on factors such as water quality, usage, and maintenance. On average, an RO membrane can last anywhere from 2-5 years. However, with proper maintenance and regular cleaning, it can last even longer.
