We are changing the treatment of wastewater and/or salt water. As clean-tech start-up, Coldep has industrialized patents from IFREMER and INSA Lyon in the aquaculture, industrial effluent and seawater pre-treatment sectors. 

Coldep solution is based on a game changer technology at 2 levels:

Operations: 
- Low energy consumption: (< 0.03kW.h / treated water m3) 
- No chemicals: no addition
- Water loss: less than 1% of the flow rate vs 30 at 40% in membrane-based processes 
- No consumables (vs regular washing and changing of filters, maintenance)
- Small footprint: vertical design

Outcome and added value for clients: 
- CAPEX performance: replacement of single-function process chain with a multi-function solution 
- Low OPEX: energy savings, very low maintenance, 0 consumables 
- Ease of use: reliability, resilience and simplicity of operation 
- Ecological: depollution, no chemicals, long lifespan 
- Ergonomic: ability to control the solution remotely and provide a continuous flow of information
