The Balearic Water Agency

This week, the Board of Directors of the Balearic Water Agency approved the proposed agreement for the award of the contract to improve the Eivissa Wastewater Treatment Plant (WWTP).

The works are divided into three lots and will cost €1,326,100.53 (VAT included). The companies awarded the contract are QUILTON SA for the desist batch, CADAGUA SA for the adaptation of the lamellar decanters and FACSA SA for the sludge dehydration.

The actions to improve the sludge line include the replacement of the dry sludge pumps, the sludge silo and two centrifuges; the installation of new pumps to transfer the thickened sludge to the centrifuges; the installation of a new thickening bridge and new equipment to add polyelectrolyte to the thickened sludge.

With regard to improvements in the physical-chemical treatment, it is planned to place coarse grids in each of the supply channels, to try to eliminate the excessive amount of towelettes and coarse fibre waste arriving from the sewage system, which collapses the screens. In addition, new bridges will be provided for the degreasing sand traps and the bridge of one of the lamellar decanters will be replaced, as well as the delgas.

The constant delays in the construction of the new Sa Coma treatment plant make it necessary to improve the quality of the treatment of the municipal wastewater that is treated and which will be useful when the Sa Coma treatment plant comes into operation and the Vila treatment plant is integrated into the pumping system of the new facilities.
