film type evaporator

Membrane evaporator, as a new type of evaporation technology, is becoming an important tool to solve water resource problems.

The principle and working mode of membrane evaporator

Membrane evaporator is a device that utilizes thin film separation technology for evaporation.

The principle is to form an evaporation condensation interface on the surface of the thin film, which converts water molecules from the liquid phase to the gas phase. Then, through the selective permeability of the film, water molecules are separated, thereby achieving evaporation and separation of water.

Membrane evaporators typically consist of evaporators, condensers, and thin films, which can be polymer films, ceramic films, or metal films.

Application of membrane evaporator in seawater desalination

Seawater desalination refers to the removal of salt from seawater, making it fresh water that can be used for agricultural irrigation, industrial water, and drinking water.

Traditional seawater desalination methods mainly include distillation and reverse osmosis, but both have problems such as high energy consumption, complex equipment, and high cost.

As a new type of seawater desalination technology, membrane evaporator has advantages such as low energy consumption, compact equipment, and easy operation.

By selectively permeating thin films, membrane evaporators can effectively separate salt from seawater and produce high-quality fresh water.

Application of membrane evaporator in wastewater treatment

Wastewater treatment refers to the treatment of industrial wastewater, domestic sewage, and other water containing harmful substances to meet discharge standards or reusable water quality requirements.

Traditional wastewater treatment methods mainly include biological treatment, chemical treatment, and physical treatment, but they have certain limitations in treating high concentration wastewater and organic matter.

Membrane evaporators are widely used in wastewater treatment due to their efficient separation ability and wide adaptability.

Through the selective permeability of thin films, membrane evaporators can separate harmful substances such as dissolved solids, organic matter, and heavy metals from wastewater, thereby achieving wastewater purification and resource recovery.

Advantages and challenges of membrane evaporators

Membrane evaporator has many advantages compared to traditional evaporation technology.
