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
