In 2001, IRIDRA managed the design of a constructed wetlands system for the wine-producing firm “Tenuta dell’Ornellaia”, Leghorn, Italy. The system consists of vertical flow constructed wetlands (SFS-v) as a first stage followed by a second SFS-h stage with recirculation to the first stage and then by a single FWS. It treats wastewater from the firm, which allows water to be reused for irrigation

Saint Germain sur Ille : a 500 PE waste stabilization pond boosted to 900 PE by addition of reed bed filters with high standards for phosphorus and total nitrogen removal.

Client: Nordborg Municipality
Location: Nordborg, Denmark
Established: 2003
Number of basins: 10
Sludge type: Activated sludge and digested sludge
Sludge volume: 350 tonnes DS/year
PE, amount: 15000

Mayfield: A 2.1 hectare, 12  bed aerated horizontal system treating airport run off contaminated with glycol based antifreeze.

Wetland to treat run-off from deicing operations contaminated with high concentrations of glycol compounds and capable of handling peak flows and loading from winter storms.

Seefood processing plant where the wastewater from cleaning fish and shellfish is treated in a VF wetland planted with papyrus.

The effluent is reused after ozonisation in the plant.

Crynant: Two 1,200m2 vertical flow reed beds operated alternately to treat 3,400 m3/d of tertiary municipal waste water.

2-stage Vertical Flow Constructed Wetland for the treatment of raw domestic sewage (French system) for 1360 people-equivalent adapted to the local resources and climate with UV tertiary treatment.

  • Adapted „French system“ for a nursing home, Hogar de Ancianos Sta. Ana y San Joaquín y Asociación Ayuda Me Perú
  • All treated wastewater is reused for irrigation of agricultural used area
  • The 2 staged wetland system treats the domestic effluent of 55 residents and employees
  • The pre-treatment is carried out on the surface of an planted, vertical flowed gravel bed wetland with 2 charging points, used alternately (2 and 2 days)
  • The post-treatment is carried out in an planted vertical flowed sand bed wetland with 4 divisions to maintain always the biologically activity in all parts of the wetland
