DEPURACI\u00d3 BIOL\u00d2GICA
\nEl tractament de l'aigua \u00e9s purament biol\u00f2gic i mec\u00e0nic, basat en el model de la natura.
\nLa pir\u00e0mide aliment\u00e0ria al bany amb tractament biol\u00f2gic de l'aigua. (????)
\nLa qualitat de l'aigua s'ha d'aconseguir mitjan\u00e7ant la gesti\u00f3 de nutrients per assolir el nivell tr\u00f2fic planificat utilitzant la cadena aliment\u00e0ria natural.
\nL'\u00e0mplia base de la pir\u00e0mide aliment\u00e0ria est\u00e0 formada per protozous com a bacteris, algues i fongs. On l'aigua natural i la llum s'uneixen, petites algues creixen r\u00e0pidament. Extreuen els nutrients de l'aigua i els utilitzen per formar biomassa i produir oxigen, la base de molts altres processos de neteja.<\/p>\n

El zoopl\u00e0ncton \u00e9s la seg\u00fcent baula de la cadena aliment\u00e0ria. S\u00f3n principalment petits crustacis els que cont\u00ednuament filtren i mengen les algues i els bacteris de l'aigua. Per tant, s\u00f3n un element important en l'exercici de la higiene, l'eliminaci\u00f3 de g\u00e8rmens pat\u00f2gens. Gaireb\u00e9 tots els pat\u00f2gens potencials no sorgeixen a l'aigua, sin\u00f3 que s\u00f3n bacteris intestinals que porten els usuaris o els vertebrats. A l'aigua rica en oxigen d'un estany per nedar, els bacteris intestinals no es poden multiplicar i s\u00f3n r\u00e0pidament eliminats pel zoopl\u00e0ncton.<\/p>\n

Les larves de mosquit tamb\u00e9 mengen pl\u00e0ncton i detritus (mat\u00e8ria org\u00e0nica en descomposici\u00f3). Respiren aire a la superf\u00edcie i, per tant, tamb\u00e9 poden prosperar en aig\u00fces lliures d'oxigen i sobre fertilitzades. No obstant aix\u00f2, s\u00f3n presa f\u00e0cil per a tots els depredadors i se'ls mengen immediatament en aig\u00fces pobres en nutrients amb una biologia ben establerta. Per tant, no apareixen en estanys de nataci\u00f3 i piscines naturals, per\u00f2 poden multiplicar r\u00e0pidament en petits tolls i en els platets de testos de les plantes.<\/p>\n

Alhora, el zoopl\u00e0ncton \u00e9s devorat per insectes i les seves larves, aix\u00ed com per larves de trit\u00f3 i petits peixos. Els peixos petits que es multipliquen r\u00e0pidament sense altres depredadors (per exemple, la gamb\u00fasia invasiva) poden delmar el zoopl\u00e0ncton fins al punt que falla com a regulador natural del fitopl\u00e0ncton. Aix\u00f2 porta a una forta proliferaci\u00f3 d'algues i aigua verda. Per tant, no s'utilitzen peixos a l'estany de nataci\u00f3 de la piscina natural.<\/p>\n

Les plantes subaqu\u00e0tiques competeixen naturalment amb les algues i tenen un paper destacat en la fixaci\u00f3 del f\u00f2sfor. En condicions favorables, les plantes dominen i impedeixen el creixement fort d'algues; en condicions desfavorables, dominen les algues. Tot i aix\u00f2, les plantes subaqu\u00e0tiques requereixen un cert nivell de nutrients en el rang mesotr\u00f2fic a oligotr\u00f2fic, ra\u00f3 per la qual s'utilitzen en estanys de nataci\u00f3 de categoria 1-3.
\n**CREC QUE FALT\u00c0RIA UNA DEFINICI\u00d3 DE LES DIFERENTS CATEGORIES DE PISCINES
\nSi la transpar\u00e8ncia \u00f2ptima de l'aigua (piscina natural, categoria 4-5) \u00e9s l'objectiu de planificaci\u00f3, s'utilitzen filtres biol\u00f2gics r\u00e0pids. El biofilm, una colorida comunitat de microorganismes que assumeix el paper de zoopl\u00e0ncton i plantes aqu\u00e0tiques, creix en superf\u00edcies exposades a forts corrents. La biopel\u00b7l\u00edcula filtra les algues i els bacteris de l'aigua i fixa els nutrients. Els filtres han d'estar equipats amb un dispositiu de neteja per poder recol\u00b7lectar el biofilm i retirar aix\u00ed els nutrients emmagatzemats del sistema tancat de la piscina natural.<\/p>\n

Les fulles i el pol\u00b7len transportats pel vent, aix\u00ed com els organismes morts, s'enfonsen fins al fons i hi formen un sediment org\u00e0nic. Aix\u00f2 \u00e9s descompost i mineralitzat per altres petites criatures, per la qual cosa els nutrients s'alliberen novament i tornen al cicle de l'aigua. En succionar el sediment, que s'utilitza com a fertilitzant natural a les lleres, es retiren del cicle grans quantitats de nutrients.<\/p><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"
