He mea nui te ariā o te horoi i roto i ngā mahi horoi kakahu, inā koa i roto i ngā whare nui pēnei i ngā hōtēra. I roto i te whai kia tutuki ai ngā paerewa horoi teitei me te pupuri tonu i te whai huatanga, kua tino whanake te hoahoa o ngā mīhini horoi kauhanga. Ko tētahi o ngā auahatanga matua i tēnei wāhanga ko te hanganga horoi rere-whakamuri. He rerekē ki te hoahoa tuku iho "kotahi te tomokanga me te kotahi te putanga", he maha ngā painga o te horoi rere-whakamuri, inā koa i roto i te penapena wai me te pūngao.
Te Mārama ki te Hoahoa o te Tomokanga Kotahi me te Hoahoa o te Putanga Kotahi
He māmā noa te hoahoa o te putanga kotahi me te putanga kotahi. He putanga motuhake tō ia wāhanga horoi i roto i te mīhini horoi kauhanga mō te wai. Ahakoa mā tēnei tikanga ka whiwhi wai māori ia wāhanga, ka nui te wai e pau ana. I te mea kua aro nui ki te oranga tonutanga, kāore i te tino manakohia tēnei hoahoa nā te koretake o te whakamahinga wai. I tēnei ao e noho nei te tiaki taiao hei kaupapa matua, kāore tēnei hoahoa i te tutuki i ngā paerewa o ēnei rā.
Te Whakatakirere whakamuriHanganga Horoi
Ko te horoi rere-whakamuri he huarahi matatau ake. I roto i tēnei hanganga, ka whakaurua he wai hou, he ma ki te wāhanga horoi whakamutunga, ka rere ki te wāhanga tuatahi, i te ritenga kē atu o te nekehanga o te rinena. Mā tēnei tikanga ka whakanuia te whakamahinga o te wai ma, ka whakaitihia hoki te para. Ko te tikanga, i a te rinena e neke whakamua ana, ka tūtaki ki te wai ma haere tonu, kia tino horoia, kia teitei hoki te ma.
Me pēheaCrere-whakamuriNgā Mahi Horoi
I roto i tētahi mīhini horoi kauhanga 16-wāhanga, kei reira ngā wāhanga 11 ki te 14 kua tohua hei horoi, ko te horoi rere-whakamuri ko te whakauru i te wai ma ki roto i te wāhanga 14 me te tuku atu i te wāhanga 11. Mā tēnei rere-whakamuri ka whakarite kia pai te whakamahinga o te wai, ka whakarei ake i te whai huatanga o te tukanga horoi. Heoi, i roto i te ao o te horoi rere-whakamuri, e rua ngā hoahoa hanganga matua: te tohanga ā-roto me te tohanga ā-waho.
Hanganga Tohanga ā-Roto
Ko te hanganga tohanga ā-roto ko te poka i ngā pakitara o te wāhanga kia taea ai e te wai te tohanga i roto i ngā wāhanga horoi e toru, e whā rānei. Ahakoa ko te whāinga o tēnei hoahoa he whakahaere i te nekehanga o te wai me te whakapai ake i te horoinga, he maha ngā wā ka uru te wai mai i ngā wāhanga rerekē i te wā e huri ana te mīhini horoi. Ka taea e tēnei whakaranu te whakaiti i te ma o te wai horoi, ka whakaiti nui i te pānga horoi whānui. Nō reira, ka kiia tēnei hoahoa ko te "hanganga horoi pseudo-counter-flow" nā ōna herenga ki te pupuri i te parakore o te wai.
Hanganga Tohanga o Waho
I tētahi atu taha, he otinga whai hua ake te hanganga tohanga o waho. I roto i tēnei hoahoa, ka honoa e te paipa o waho te raro o ia wāhanga horoi, kia taea ai te pēhi i te wai mai i te wāhanga horoi whakamutunga ki runga i ia wāhanga. Mā tēnei hanganga ka noho ma te wai i roto i ia wāhanga horoi, ka ārai i te rere whakamuri o te wai paru ki roto i ngā wāhanga ma. Mā te whakarite kia pa noa te rinena e neke whakamua ana ki te wai ma, ka mau tonu te kounga horoi me te ma whānui o te horoinga i tēnei hoahoa.
Heoi anō, me whai hoahoa rua-wāhanga te hanganga tohanga o waho. Ko te tikanga ka wehea ia wāhanga horoi kia rua ngā wāhanga motuhake, me nui ake ngā takirere me ngā wāhanga. Ahakoa ka piki ake te utu katoa, ko ngā painga o te horoi me te whai huatanga ka whakamana i te haumitanga. He mea nui te hoahoa rua-wāhanga ki te pupuri i te pono o te tukanga horoi rere-whakamuri, me te whakarite kia horoia pai ia wahi rinena ki te wai ma.
Te Whakatika i te Pahuka me ngā Parapara e Mānu ana
I te wā e horoi ana, ka puta he pahuka me ngā paru e mānu ana i te whakamahinga o ngā hopi horoi. Ki te kore e tangohia wawetia ēnei hua taha, ka pā kino te kounga o te horoinga, ka whakapoto hoki i te roa o te ora o te rinena. Hei whakatika i tēnei, me whai pū kōhao waipuke ngā wāhanga horoi tuatahi e rua. Ko te mahi matua o ēnei pū kōhao waipuke ehara i te mea ko te tuku wai nui anake, engari ko te tango atu hoki i te pahuka me ngā paru e mānu ana i puta mai i te whiunga tonu o te rinena i roto i te pahu.
Mā te noho mai o ngā kōhao waipuke ka noho kore poke te wai horoi, ka pai ake te whai huatanga o te tukanga horoi. Heoi, ki te kore te hoahoa e hanga i tētahi hanganga wāhanga-rua katoa, ka uaua te whakatinana i te tukanga waipuke, ka whakararu i te kounga o te horoi. Nō reira, he mea nui te hoahoa wāhanga-rua, me ngā kōhao waipuke, kia tutuki ai ngā hua horoi tino pai.
Whakamutunga
Hei whakamutunga, ko te hanganga horoi rere-whakamuri he whanaketanga nui i roto i te hoahoa horoi kauhanga, e aro ana ki ngā herenga o te hoahoa tuku iho kotahi te tomokanga me te putanga kotahi. Mā te whakanui ake i te whai huatanga o te wai me te whakarite i te kounga horoi teitei, ka hangai te hanganga horoi rere-whakamuri ki te arotahi hou ki te pumau me te ma. I roto i ngā hoahoa matua e rua, ko te hanganga tohanga o waho e tu ke ana mō tōna whai huatanga ki te pupuri i te rere o te wai ma me te aukati i te rere whakamuri, kia pai ai te kounga horoi.
I te whanaketanga tonu o ngā mahi horoi kākahu, he mea nui te whakamahi i ngā hoahoa matatau pēnei i te hanganga horoi rere-whakamuri. Mā te whakaurunga o ngā āhuatanga pēnei i te hoahoa rua-wāhanga me ngā kōhao waipuke ka whai hua ake te tukanga horoi, kia noho ma tonu ai te kākahu, kia tiakina pai ai hoki.
