Enlargement of the wastewater treatment plant at Almansa (Albacete)

The project and construction of the expansion and improvement of the wastewater treatment plant in Almansa (Albacete) is being carried out by Lantania, in a joint venture with CHM Obras e Infraestructuras. This project, designed to serve a population equivalent of about 63,500 inhabitants, meets the wastewater treatment needs of the city of Almansa and the El Mugrón industrial estate.

The scope of the project includes appropriate wastewater treatments for nutrient removal and tertiary treatment, as well as upgrading the existing facilities. The works will make it possible to obtain a quality of treated water that can be reused for irrigation.

The treatment system will have pretreatment, a storm tank for storage and subsequent treatment of excess water in rainy weather, and biological treatment using activated sludge with prolonged aeration and nutrient removal. It also includes a tertiary treatment for the reuse of treated water with lamellar settling, microfiltration and ultraviolet disinfection.

The sludge treatment line will consist of gravity thickening, mechanical drying with a centrifuge, pumping and, finally, storage of the dried sludge in a hopper.

For odour treatment, there is a deodorisation system using activated carbon.

The treated water is stored in a reservoir from where it is pumped to the irrigation community’s reservoir or to the wastewater pipe that discharges into the Saladar irrigation canal.
