Codsiyada
Soo saarista biyaha macdanta, biyaha guga, ama dareeraha kale ee nadiifka ah.
Daawaynta cabitaanka biyaha qasabada, biyaha dusha sare, biyaha ceelka iyo biyaha webiga.
Daaweynta RO.
Daaweynta, dib u warshadaynta iyo dib u isticmaalka biyaha wasakhda warshadaha.
Waxqabadka Sifeynta
Alaabtan waxaa la caddeeyey in ay hoos ku leedahay saamaynta shaandhaynta iyadoo loo eegayo shuruudaha adeegga ilaha biyaha ee kala duwan:
Walaxda | Saamaynta |
SS, Qaybaha> 1μm | Heerka saarista ≥ 99% |
SDI | ≤ 3 |
Bakteeriyada, Fayrasyada | > 4 log |
Turbidity | <0. 1NTU |
TOC | Heerka saarista: 0-25% |
* Xogta sare waxaa lagu helay shuruud ah in qulqulka biyaha quudinta ay tahay <15NTU. Alaabtani waxay u qalantaa alaabada la xidhiidha biyaha la cabbo.
