LM4040 indicates the manufacturer brand of Jiangsu Longmem Technology Co., Ltd and the size of this reverse osmosis membrane element
1,Brackish water reverse osmosis (BWRO) membrane elements are used in the process of desalinating or purifying brackish water. Brackish water typically contains dissolved salts,minerals and other viruses, but at a lower concentration than seawater.
2,Reverse osmosis is a water purification process that uses a semi-permeable membrane to remove ions, molecules, and larger particles from the brackish water. The BWRO membrane element is a crucial component of this process.
3,The BWRO membrane element consists of multiple layers of thin film composite membranes that are designed to selectively allow only pure water molecules to pass through while rejecting the dissolved salts and impurities. These membranes have microscopic pores that can effectively filter out contaminants as small as 0.0001 microns.
4,During operation, brackish water is forced through the BWRO membrane under high pressure, causing pure water molecules to permeate through the membrane while leaving behind concentrated brine or reject stream containing most of the salts and impurities.
5,The purified permeate stream obtained from the BWRO process can be used for various applications such as drinking water supply, irrigation purposes, industrial processes, and etc.
6,It's important to note that regular maintenance and cleaning are required for maintaining optimal performance of BWRO membranes as fouling from scaling or organic matter can reduce their efficiency over time.
Overall, brackish water reverse osmosis membrane elements play a vital role in providing access to clean and safe drinking water by efficiently removing contaminants from brackish sources.
RO Membrane Film
RO Membrane Element
The production of reverse osmosis (RO) membrane elements involves several steps:
The first step is to create a thin, flat sheet of the RO membrane material. This is done by spreading a liquid polymer solution onto a casting surface, such as a glass plate or a rotating drum. The solution is then allowed to dry, forming a solid thin film.
After the casting process, the thin film is treated with chlorine gas or another oxidizing agent to improve its chemical resistance and remove any impurities.
The chlorine-treated thin film is then sintered by heating it at high temperatures. This step helps to further enhance the membrane's chemical stability and mechanical strength.
A mesh-like spacer material is applied on top of one side of the sintered membrane sheet. This spacer creates channels for water flow through the element and helps maintain separation between layers during assembly.
Multiple layers of spacer-applied membranes are rolled together into a tightly wound spiral configuration, with each layer separated by feed spacers that ensure proper water flow distribution throughout the element.
The ends of the spiral-wound element are capped off with end caps made from various materials like plastics or metals (e.g., epoxy resin). These caps provide structural support and prevent leakage at the ends of the element.
Each RO membrane element undergoes rigorous testing to ensure its performance meets industry standards before it can be approved for commercial use.
It's important to note that this process may vary slightly depending on specific manufacturing techniques used by different companies or variations in product designs.
