Liquid-liquid separation/gas-liquid separation

■Conventional separation methods

1. （1）Settling
2. （2）Distillation
3. （3）Centrifugation
4. （4）Absorption

Principle and mechanism: What is a Coalescer?

1. Liquid-liquid separation
2. Gas-liquid separation

A Coalescer cartridge has a special multi-layered structure which instantaneously breaks down the emulsion (clouding) by running the fluid through the Coalescer cartridge in the direction IN -> OUT. Separation occurs due to the difference in specific gravity between fluids.

The flow of the fluid proceeds as shown above, and coalescing is conducted on the dispersed fluid particles of 0.5 to 50 μm within the Coalescer cartridge to let them grow to droplets of 2 to 6 mm. Separation is addressed by the specific gravity of each fluid, and only the necessary fluid is sent to the later stage of the process.

Media of Coalescer Cartridge

WAFTEC changes the media of the Coalescer cartridge to suit the characteristics of the fluids handled by the customer.
In general, glass fiber is popularly used by many plants, and carbon fiber is recommended if the fluid reaches high temperatures.

• Glass Fiber (normal)
• Glass Fiber (fine)
• Polypropylene
• Carbon fiber
• Rayon

Principle and mechanism: What is solid matter removal?

・Fluid contains high levels of foreign matters and impurities

1. Principle and mechanism

By passing fluid such as oil or water containing impurities through the cartridge in the direction OUT -> IN, the fluid and impurities are separated.
Only the necessary fluid is sent to the later stage of the process.

Features of the Micro Filter

1. ・Wide product lineup (nominal size 1 μ to 150 μ)
2. ・Capable of handling fluids at temperatures from below freezing to high
3. ・Also capable of handling gas
