Intensified (aerated) wetland for wastewater treatment of 800 employees at the administrative center of a mining company, situated near Belo Horizonte, Brazil.


Conception: 2 Septic Tanks for pre-treatment, aerated wetland as main treatment and horizontal flow constructed wetland post treatment.  

Wetland project and execution by Rotária do Brasil, Landscaping only execution by Rotária do Brasil.

 

Allenwiller : a 1700 m², vertical flow reed bed (French system) plus a 960 m² second stage unsaturated vertical flow reed bed filter, treating 495 m3/d of domestic effluent from three villages (1100 PE) in Alsace.

At Escurolles, in central France (Allier), a reed bed fed with raw sewage assures primary and secondary treatment for 705 PE , followed by a tricking filter for polishing and nitrification 

The municipal centralised treatment plant (a classic activated sludge technology) for the wastewater produced by the municipality of Jesi (Ancona province – central Italy) has been upgraded in the year 2002, with the realisation of a new “nitrification-denitrification” compartment and a hybrid Constructed Wetland as polishing stage. 

One of the largest and most efficient wastewater treatment plant with french system reed bed filter in France.

Nominal capacity : 4000 p.e. with an extension to 6000 p.e. 

2-stage vertical flow reed bed filter treating raw domestic sewage (French system) with a capacity of 650 P.E. Treated effluent goes through a filtering ditch and is rejected into the river Bourdic.

Pouembout : a 250 p.e. reed bed filter was created to replace a deficient waste stabilization pond.

A vertical flow reed bed (French system) and a vegetated polishing zone (surface flow wetland)  treating 117m3/d of domestic effluent from a village with variable population

-          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
