What are microfiltration membranes (NF), ultrafiltration membranes (UF), nanofiltration membranes (NF), and reverse osmosis membranes (RO)?

Released Date: Aug 13,2015 Article Source: Yuanlai Water Treatment

With the development of industry, market demands and the requirements of environmental protection, the rational utilization and protection of water have been receiving increasing attention. It also puts forward higher requirements for water treatment technology. In water treatment equipment, membranes have become the core components, and their performance directly affects the quality of treatment. At the same time, the development of membrane technology has also given rise to different types of membranes. Now let's talk about what microfiltration membranes (NF), ultrafiltration membranes (UF), nanofiltration membranes (NF), and reverse osmosis membranes (RO) are? Type definition: Microfiltration membranes (NF) are a type of organic or inorganic membrane between conventional filtration and ultrafiltration, which is based on the size of the pores and uses pressure gradient as the driving force to selectively separate substances with a particle size larger than the pore size. Ultrafiltration membranes (UF) use pressure difference as the driving force and are based on ultrafiltration technology to selectively separate substances through the microporous structure on the membrane surface

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
