Our products

COLDEP developed its innovative process of vacuum airlift column based on the principle of partial vacuum airlift, supplied with microbubbles through high pressure diffusers.

This system allows both hydraulic circulation, gas rebalancing and the extraction of particulate matter and dissolved matter by flottation. It's fully automated and can be programmed to operate continuously or in adjustable time slots.

The choice of the VAL model defines the size and power of the other components of the installation : the vacuum pump, the gravity separator and the harvester.

The compressor, required only in particle extraction mode, is sized for the selected VAL model if it’ not possible to connect the installation to an existing compressed air network.
