- Possibility of depleting water in one gas and / or enriching it in another.
- Extraction of particles <40 µm, bacteria, viruses, dissolved materials, oils, hydrocarbons.
- Water loss less than 1 % of the initial volume.
degassing - compatibility - particulate extraction
Water treatment in the Oil & Gas sector
The bubbles associated with the vacuum make it possible to achieve unprecedented performance in degassing and purification. COLDEP thus provides an innovative solution to different stages of process water management, in particular: treatment of raw seawater before injection, and treatment of process water before reinjection.
Maximum concentration in WHERE of the discharged water
Electricity consumption per m³ of treated water
Maximum concentration of oils / hydrocarbons in discharged water
Particle extraction efficiency
Treated water flow / hour
No coagulants-flocculants, no filters
The free passage design of the COLDEP column allows water treatment without risk of clogging, easy to use and low maintenance. The possibility of extracting the gases and materials present within the same process makes it possible to reduce the number of equipment used.
Particulate extraction - Compatibility - Biosecurity
Water pre-treatment before desalination
The COLDEP process makes it possible to simplify the stages of pre-treatment of seawater before desalination, by providing a solution to the main technical constraints impacting reverse osmosis membranes: Clogging of filters linked to particles in the water – Impacts and cost of chemical additives – Energy cost of the solutions put in place to solve these problems.
Particle extraction efficiency
Maximum electricity consumption per m³ of treated water
Treated water flow / h
No consumables or filters used
The microbubbles created in the system trap impurities as they rise and create a scum at the top of the column. This scum which is sucked up by the vacuum carries with it the particles which are trapped inside. These extracted particles are between 0.3 and 100 µm and are not trapped in conventional systems. This free passage technology thus never clogs or develops preferential passages.
