Ecodisk™ Filter - Hautecombe Abbey (73)

Ecodisk™Filter technology : the combination of an Ecodisk™ and a drum filter

Customer needs

The Hautecombe Foundation entrusts OTV Sud — a subsidiary of  Veolia Water Technologies — with the rehabilitation of the Hautecombe Abbey wastewater treatment plant with a capacity of 510 population equivalent (PE). The historical site requires a compact technology that can be integrated in this exceptional site.

The client wished to develop its plant while respecting the following parameters: 

• Compactness and architectural integration
• Conservation of existing equipment
• Efficient treatment of carbon and nitrogen pollution 
• Autonomous and simple operation

The solution

Thanks to the modularity of the Ecodisk™ solution, OTV in partnership with PMT — a second subsidiary of Veolia Water Technologies — proposed the implementation of Ecodisk™ Filter. biological disk integrating a filtration for separation of treated water.

The solution includes:

• The reuse of the lift station, automatic bar screen and compactor
• The conservation of the existing decanter digester
• The installation of a two meter in diameter biodisk for a surface of 1900 square metre and a drum filter in a single equipment
• The creation of a counting channel.

Advantages of the solution

• Reinforcement of the treatment capacity
• Ecodisk Filter: two treatments in one single equipment
• Treatment of carbonaceous and nitrogenous pollution in compliance with the new NH4<5 mg/l (ammonium less than five milligrams per litre) regulation
• Sludge treatment by séparation on a drum filter
• Low energy installation
