The aim of this project was the design / construction, pre-start and start-up of the Palmeira WWTP, whose treatment process includes: preliminary treatment (sieving, sedimentation and degreasing). In the solid phase treatment, the mechanical thickening and dewatering of the sludge by band filter was included. Also included was the treatment of odours produced in the facility. The contract also included the outfall for discharge of treated effluent into in the receiving environment.
