Anionic polymers such as sodium carboxymethyl cellulose (CMC) are commonly used for treating dairy wastewater, after the pH is adjusted to 4.2–4.5, however, this process consumes both acid and base while the process stability is highly dependent on the pH. In this study, a novel coagulant, chitosan, was tested in dairy wastewater.
