The Balearic Water Agency

The Balearic Water Agency is installing a deodorisation system using a trickling filter biofilter to treat the air coming from the Playa de Muro Wastewater Treatment Plant (WWTP). During the works, which are expected to be completed in approximately three weeks, a series of maintenance and equipment upgrades will be carried out, totalling an investment of 198,440 euros (including VAT), of which 108,800 euros will go to the deodorisation system.

The trickling filter biofilters are based on the capacity of microorganisms to transform certain organic and inorganic pollutants in the gas phase into other, less odorous compounds.

This is the first of two major actions planned for this year at the Playa de Muro facilities. During the first half of the year, the Agency will put out to tender the service of removing the sludge from the WWTP lagoons for a maximum of 566,857.50 euros (including VAT).

At present, the Playa de Muro wastewater treatment plant has two wastewater lines, one consisting of a lagoon system and the other with an activated sludge system. In total, the two lines can treat a maximum flow of 9,000 m3/day, which is approximately the average flow during the high season. The removal of the sludge will allow the lagoons to perform their function as a soft treatment system and will significantly reduce the odours emitted by the plant.
