Design and installation of a dry dock water treatment unit
Design and installation of a dry dock water treatment unit at the port in Sète.
The issue faced by our client
In a cluster with SADE Cght, the Montpellier branch, we worked on the public design and construction project for dry dock wastewater collection, storage and treatment units.
Nomado constructed the equipment in a single compact system:
1 x scrubber
1 x coagulation/flocculation
1 x lamella settling tank
1 x sand and activated carbon filtration
1 x microfiltration
This unit will allow the Port of Sète to obtain the “Vague Bleu Carénage” seal, awarded to shipyards that invest in environmentally-friendly dry dock areas.
The treatment system is mounted entirely in a container and includes an “exhaustive” treatment process such as:
Coagulation reactor with injection of coagulant, flocculation reactor with flocculant injection, Lamella settling tank,
Activated carbon adsorption,
Our partner and co-service provider constructed the 81 and 47 m3 stormwater control units.
To summarise, Nomado:
Reference standards: Prefectoral order. French law on water and water bodies of 30 December 2006 in the Environment Code. European Parliament and Council Decision of 20 November 2001 establishing a list of priority substances in water and modifying Directive 2000/60/EC.
