Aquest mat\u00ed l’alumnat de quart ha visitat la depuradora del Far. A l’\u00faltim tema de coneixement del medi natural vam treballar la potabilitzaci\u00f3 i depuraci\u00f3 de les aig\u00fces residuals. Per tant, ha estat molt profit\u00f3s fer una excursi\u00f3 com aquesta perqu\u00e8 hem pogut veure el procediment en directe.<\/p>\n

En Pere i en Xavier ens han explicat, molt amablament, tot el proc\u00e9s. La\u00a0depuraci\u00f3 comen\u00e7a quan l\u2019aigua arriba a les reixes de desbast de la depuradora, on es separen els s\u00f2lids m\u00e9s grans. L\u2019aigua transporta greixos i olis, que es retiren als equips de flotaci\u00f3, on per difer\u00e8ncia de densitat floten i queden a la superf\u00edcie. El seg\u00fcent pas \u00e9s el tractament biol\u00f2gic: es decanta la mat\u00e8ria org\u00e0nica i inorg\u00e0nica, es digereix la mat\u00e8ria org\u00e0nica i finalment es separa l\u2019aigua depurada dels fangs biol\u00f2gics.\u00a0Finalment les aig\u00fces depurades tornen al medi, un rec prop de la zona. Els fangs s\u00f3n reutilitzats com a compostatge. Hem quedat bocabadats al saber que es solen treure unes quatre tones mensuals d’adob i es depuren 120.000 litres d’aigua di\u00e0riament.<\/span><\/p>\n

Despr\u00e9s de veure tot el funcionament, en Pere ens ha fet un petit experiment. En un recipient amb aigua, ha desfet paper higi\u00e8nic i tovalloletes, hem comprovat la difer\u00e8ncia entre un producte i l’altre. Un \u00e9s biodegradable i es desf\u00e0 completament i l’altre, en canvi, forma nusos i obstrueix la depuraci\u00f3. Per tant, hem de ser conscients de que el clavegueram no \u00e9s un contenidor d’escombraries.<\/p>\n

Una vegada m\u00e9s, donem les gr\u00e0cies a en Pere i a tot l’equip per acollir-nos i mostrar-nos les instal\u00b7lacions.<\/p>\n

Molt\u00edssimes gr\u00e0cies!<\/p>\n
