The Airlift vacuum column

The technology developed by COLDEP combines the known principle of the airlift and foaming-skimming with a partial vacuum created in a column that multiplies the performance of the observed phenomena in a simple airlift system and brings up new features.

This unique process has three main functions:

• Water circulation
• Managementof dissolved gases
• The separationof suspended solids and liquids

• Treatment with free passage (without filter) avoids clogging
• The pressure drop is very low, hence an excellent energy efficiency
• Energy consumption is very low, usually <2kW
• A purely physical process that does not commit any additives and causes no rejection in the circuit
• No moving (wear) or metal (corrosion) parts come into play in the operation of the column , the lifetime of the device is exceptional
• Sturdy materials and easy maintenance ensure an inexpensive use
• The system is designed to separate all the electrical device from the column and to store them in a protected environment, ensure further reliability.
