Implementation of a combined passive treatment system (biodigester and wetland) for the treatment of construction site effluents.
ABOUT IT
Project description
The project implemented a integrated sanitary wastewater treatment system on the construction site, using:
Anaerobic biodigester 10,000 liters for primary treatment;
Subsurface horizontal constructed wetland with HDPE blanket for effluent polishing;
Final destination through infiltration trenches dimensioned according to NBR 17076:2024.
System capacity:
He meets 200 people;
Flow rate 10 m³/day;
Organic load of 10,800 gBOD/d.
The treatment is carried out right on the construction site, eliminating the need for external transport and disposal.
