Na de hogy ker\u00fcl a Liquid3 (Liquid tree = foly\u00e9kony fa) \u00c9rd f\u0151ter\u00e9re, \u00e9s mi is az pontosan? Err\u0151l besz\u00e9lgettem Krausz Krisztin\u00e1val, az eszk\u00f6zt forgalmaz\u00f3 Ecogarden Kft. tulajdonos\u00e1val \u00e9s Koltai Eszterrel, a c\u00e9g \u00fcgyvezet\u0151j\u00e9vel.<\/p>\n

Krausz Krisztina elmondta, az eszk\u00f6z nem helyettes\u00edti a f\u00e1kat. Kifejezetten olyan v\u00e1rosi helyekre sz\u00e1nj\u00e1k, ahol valamilyen okb\u00f3l nincs lehet\u0151s\u00e9g elegend\u0151 f\u00e1t, f\u00fcvet vagy m\u00e1s n\u00f6v\u00e9nyzetet telep\u00edteni. Vagyis nem a hagyom\u00e1nyos z\u00f6ld infrastrukt\u00fara versenyt\u00e1rsa, hanem annak kieg\u00e9sz\u00edt\u0151je.<\/p>\n

A m\u0171k\u00f6d\u00e9s alapja meglep\u0151en egyszer\u0171. A szerkezet egy leveg\u0151pump\u00e1val besz\u00edvja a k\u00f6rnyezet szennyezett leveg\u0151j\u00e9t, majd azt a tart\u00e1lyban \u00e9l\u0151 alg\u00e1kon vezeti kereszt\u00fcl. A fotoszint\u00e9zis sor\u00e1n az alg\u00e1k sz\u00e9n-dioxidot k\u00f6tnek meg \u00e9s oxig\u00e9nt termelnek, a rendszer pedig a forgalmaz\u00f3 elmond\u00e1sa szerint a sz\u00e1ll\u00f3 por \u00e9s bizonyos neh\u00e9zf\u00e9mek kisz\u0171r\u00e9s\u00e9re is k\u00e9pes.<\/p>\n

A tart\u00e1lyban nagyj\u00e1b\u00f3l egy h\u00f3nap alatt jelent\u0151s mennyis\u00e9g\u0171 algabiomassza keletkezik. Ekkor a mintegy 600 literes folyad\u00e9kot lecser\u00e9lik, a rendszert friss v\u00edzzel t\u00f6ltik fel, \u00e9s indulhat el\u00f6lr\u0151l a folyamat. Az elhaszn\u00e1lt alg\u00e1s v\u00edz pedig nem hullad\u00e9k, a tervek szerint a k\u00f6rnyez\u0151 z\u00f6ldfel\u00fcleteken haszn\u00e1lj\u00e1k majd fel tr\u00e1gyak\u00e9nt.<\/p>\n

A forgalmaz\u00f3 szerint egy Liquid3 nagyj\u00e1b\u00f3l egy kifejlett fa l\u00e9gtiszt\u00edt\u00f3 teljes\u00edtm\u00e9ny\u00e9vel vethet\u0151 \u00f6ssze, havonta kb. 4000 k\u00f6bm\u00e9ter leveg\u0151t sz\u0171r \u00e9s tiszt\u00edt meg. A technol\u00f3gia mellett sz\u00f3l, hogy t\u00e9len is m\u0171k\u00f6dik, amikor a lombhullat\u00f3 f\u00e1k m\u00e1r elvesz\u00edtett\u00e9k leveleiket, \u00e9ppen abban az id\u0151szakban, amikor a k\u00f6d\u00f6s, p\u00e1r\u00e1s id\u0151 \u00e9s a f\u0171t\u00e9si szezon miatt a v\u00e1rosi leveg\u0151 k\u00fcl\u00f6n\u00f6sen rossz.<\/p>\n

A tiszt\u00edt\u00e1s \u00e9s sz\u0171r\u00e9s mellett van m\u00e9g egy nagyon hasznos k\u00e9pess\u00e9ge: adatokat szolg\u00e1ltat.
\nA tervek szerint ugyanis az algabiomassz\u00e1b\u00f3l havonta mint\u00e1t vesznek, amelyet akkredit\u00e1lt laborat\u00f3riumban vizsg\u00e1lnak meg.

Ez k\u00fcl\u00f6n\u00f6sen \u00e9rz\u00e9keny pont lehet egy olyan t\u00e9rs\u00e9gben, ahol a lakoss\u00e1got id\u0151r\u0151l id\u0151re aggasztja az ipari eredet\u0171 l\u00e9gszennyez\u00e9s.<\/p>\n
