The inventory is based on measured operating data taken from national statistics, literature data and / or calculated via energy carrier composition in combination with (literature-based) combustion models.0The data set represents the country / region specific situation, focusing on the main technologies, the region specific characteristics and / or import statistics.The waste water is treated in a physical-chemical-biological waste water treatment plant. The first steps of the waste water treatment are mechanical methods like rakes and screens for the removal of coarse material contained in the waste water, as well as grit chamber and primary settlement tank, where smaller solids such as sand and flaky components are removed by sedimentation. Afterwards these solid contaminants have to be treated solely. The main step in the treatment of the waste water is done by micro organisms. Aerobe bacteria live in the sludge in the activated sludge tank. They use the organic substances contained in the waste water for their metabolism for which they also need oxygen. The oxygen is brought into the water by nozzles or in a mechanical way, e. g. by bubblers. The organic substrates are used by the micro organisms for building up cell mass (anabolism) and for gaining energy (catabolism). The end products of the latter are water, carbon dioxide, nitrate, sulphate, and others. In a complex process called denitrification also nitrate and nitrite can be eliminated from the waste water, in the course of which nitrogen gas develops. To support this process, changes between aerobe and anaerobe phases are needed. Phosphate can be eliminated during the waste water treatment by precipitation with chemicals such as Al3+ ions, Fe2+ ions or Ca2+ ions. This process leads to an additional accumulation of sludge. A particular treatment of the micro organisms with alternating aerobe and anaerobe phases makes that special bacteria accumulate more phosphate than they need for their metabolism. So the phosphate can be removed with the excess sludge. It is important that there is no nitrate or nitrite present in the anaerobe phase that could be used as an electron acceptor. The biomass must be held back in the waste water treatment plant, so the last step is again a sedimentation process. The sludge deposits in the final sedimentation and most of it is returned to the activated sludge tank. The excess sludge is removed and treated for the disposal, e. g. it is dried. The treated waste water is discharged into the receiving water.Provision of a standard technical product according to the applied technology.Unit process, single operationAttributionalNoneNot applicableAll data used in the calculation of the LCI results refer to net calorific value.NoneCut-off rules for each unit process: Coverage of at least 95 % of mass and energy of the input and output flows, and 98 % of their environmental relevance (according to expert judgement).

This hypothesis is based on the results of previous LCA studies of ENEA.
Direct CO2 emissions to the environment from Lariana WWTP processes have not been considered (according to IPCC guidelines).
Because it was not possible to have information on the specific contaminants of the product systems water effluents, the evaluation of the potential impact connected to the release to the environment of the treated water effluent has been calculated considering the effluent mass of the specific product system and the contaminant concentration of the treated WWTP effluent.

Combination with individual unit processes using this commodity enables the generation of user-specific (product) LCAs. The data set does not necessarily fit for any possible specific supply situation - especially if significantly different technology routes exist - but is representative for a common supply chain situation.Sphera Solutions GmbH2022-03-01T00:00:00.000ILCD format 1.1Sphera Solutions GmbHNo official approval by producer or operator2022-03-01T00:00:00.00000.00.001Data set finalised; entirely publishedGaBi databasesSphera Solutions GmbH / ENEAtrueOtherGaBi (source code, database including extension modules and single data sets, documentation) remains property of Sphera Solutions GmbH.
