Aerobic biological water treatment

exelio specialises in domestic effluent treatment for small and medium-sized towns (from 250 to 5000 PE).

We select and design the processes depending on the performances to be reached, the available space, the budgets to be kept within, the criteria for integration with the landscape, etc…

pamco biorotors

exelio manufactures and markets pamco biorotors.

There are numerous advantages with a treatment installation using pamco biorotors :

  • high purification performances
  • compact installations that are always very ergonomic for the operator
  • remarkable resistance in the event of load fluctuations
  • very low operating expenditure
  • excellent integration with the landscape

Our treatment plants using pamco biorotors are ideal for small and medium-sized towns (100 to 3000 PE).

Two solutions are possible :

  • exelio carries out the design and construction of the installation using pamco biorotors
  • exelio sells the biorotor product by itself or including its tank and cover. In this case, our customers also benefit from our informed advice on the whole installation

There is more information on the type of pamco biorotors available in the pamco section.

Activated sludge

exelio constructs activated sludge treatment plants :

  • with water clarification separate from the biological tank (“traditional” activated sludge)
  • SBR (Sequential Biological Reactor) type

The advantages of an exelio activated sludge treatment installation are :

  • high purification performances
  • compact installations that are always very ergonomic for operators
  • controlled operating expenditure
  • excellent integration with the landscape

An exelio “traditional” activated sludge installation is ideal for small and medium-sized towns (250 to 5000 PE).

The advantages of an exelio SBR activated sludge plant are :

  • very compact installations
  • minimised capital expenditure
  • optimised purification performances and operating expenditure

An exelio SBR type activated sludge installation is ideal for biodegradable industrial effluents.

Green water treatment installations, reed bed filtration

In association with Atelier Reeb of Strasbourg, exelio supplies green water treatment installations (reed bed filtration, etc.) for the treatment of domestic wastewater and some industrial effluents.

The advantages of the green exelio-Atelier Reeb treatment installation are :

  • very simple installations, with a small amount of equipment, and so does not require very much maintenance and cleaning
  • good discharge levels
  • no discharge of sludge for at least 10 years as the product extracted is a good organic enriching agent
  • hardy installations that are remarkably resistant to load fluctuations
  • control of odours thanks to a predominantly aerobic process
  • has been in use in France for 20 years
  • very low operating expenditure
  • excellent integration with the landscape

Green exelio-Atelier Reeb treatment installations are especially suitable for small towns and villages in rural areas (50 to 2000 PE).
