Arti nilai turbidity dari hasil analisa laboratorium maksudnya apa sich ? Dibilang turbidity kecil itu nilainya berapa, kalau besar juga berapa. Sebagai tambahan aza, turbidity dalam bahasa Indonesia adalah kekeruhan. Ini hasil dari baca dibuku :

Turbidity < 0.1 NTU is required for effective disinfection.

Turbidity ~ 5 NTU in drinking water is visible but generally acceptable to consumers.

Turbidity < 10 NTU is generally regarded as low turbidity

Turbidity > 10 NTU is generally regarded as turbid

Turbidity > 50 NTU is generally regarded as high turbidity
