★Ọrụ nke asịd organic na ngwaahịa mmiri

1. Belata nsị nke ọla dị arọ, gbanwee amonia molekul na mmiri aquaculture, ma belata nsị nke amonia na-egbu egbu.

2. Asịd organic nwere ọrụ iwepụ mmetọ mmanụ. E nwere ihe mkpuchi mmanụ n'ime ọdọ mmiri ahụ, yabụ enwere ike iji acid organic.

3. Asịd organic nwere ike ịchịkwa pH nke mmiri ma mee ka ọrụ mmiri dị mma.

4. Ọ nwere ike ibelata oke mmiri, mebie ihe ndị dị ndụ site na mmiri na-agbaze na mgbagwoju anya, ma melite nrụgide elu mmiri.

5. Asịd organic nwere ọtụtụ ihe ndị na-eme ka ihe dị arọ sie ike, nke nwere ike ime ka ígwè dị arọ dị mgbagwoju anya, mee ka ha dị ọcha ngwa ngwa, belata nrụgide elu mmiri, gbazee oxygen dị n'ikuku ka ọ ghọọ mmiri ngwa ngwa, melite ikike ikuku oxygen na-abawanye na mmiri, ma chịkwaa isi mmiri na-ese n'elu mmiri.

★Mmejọ n'iji asịd organic eme ihe

1. Mgbe nitrite dị n'ọdọ mmiri gafere ọkọlọtọ, ojiji nke organic acids ga-ebelata pH ma mee ka nsí nke nitrite dịkwuo elu.

2. A gaghị eji ya na sodium thiosulfate. Sodium thiosulfate na-emeghachi omume na acid iji mepụta sulfur dioxide na elemental sulfur, nke ga-emerụ ụdị ọmụmụ.

3. Agaghị eji ya na sodium humate. Sodium humate adịghị mma nke ukwuu, mmetụta ya ga-ebelata nke ukwuu ma ọ bụrụ na ejiri ha abụọ.

1. Ọnụọgụ ọgwụ: mgbe etinyere otu asịd organic ahụ na nri anụmanụ mmiri, mana oke ya dị iche, mmetụta ya dịkwa iche. E nwere ọdịiche dị na oke ibu, oke uto, oke ojiji nri na arụmọrụ protein; N'ime oke mgbakwunye asịd organic, site na mmụba nke mgbakwunye asịd organic, a ga-akwalite uto nke ụdị osisi a kụrụ, mana mgbe ọ gafere oke ụfọdụ, oke ma ọ bụ obere mgbakwunye asịd organic ga-egbochi uto nke ụdị osisi a kụrụ ma belata ojiji nke nri, mgbakwunye asịd organic kacha mma maka anụmanụ mmiri dị iche iche ga-adị iche.

2. Oge mgbakwunye: mmetụta nke itinye asịd organic n'ọkwa uto dị iche iche nke anụmanụ mmiri dị iche.
