The Blanca wastewater treatment plant has managed to reduce treatment costs by almost 20 percent and improve water quality through the application of innovative anaerobic purification techniques, pioneering in Europe, carried out within the framework of the Life Ramses project.
This has involved an investment of 1,558,000 euros from the Ministry of Water, Agriculture, Livestock and Fisheries.
The director of the Regional Entity for Sanitation and Wastewater Treatment (Esamur), Joaquín Ruiz, and the Mayoress of Blanca, Esther Hortelano, visited this week in plant the improvement works carried out.
Ruiz stressed that "a very good effluent quality has been achieved, in addition to optimizing the electric consumption".
He added that "other environmental objectives have also been achieved, such as improving the stability of the biological process, the valorization of the biogas obtained in the purification process and the reduction of the volume of sludge generated, allowing also its valorization in agriculture as an organic amendment" .
This treatment plant was built in 2001 and a year later it was extended to incorporate the tertiary treatment system, with an investment of 1,456,000 euros.
Currently it is cleaning some 257,222 cubic meters for an equivalent population of 5,186 inhabitants.
It has an irrigation concession by the Segura Hydrographic Confederation, as well as the reuse of purified water in agriculture in favor of the Community of Irrigators Zone II Vega Alta y Media, which covers a concession area of ​​about 3,000 hectares.
Anaerobic treatment
The anaerobic treatment system that has been operating experimentally for more than a year in the Blanca treatment plant has exceeded the expected expectations, by achieving high rates of elimination of organic matter, by more than 70 percent, and considerable reductions in consumption. energetic.
This is compounded by the competitive cost of construction of the system and its low maintenance.
