ABSTRACT:
The present invention provides methods of treating or clarifying a turbid wastewater containing at least one contaminant selected from the group consisting of proteinaceous materials, fats, oils, and other biological contaminants. The methods of the present invention include the steps of (a) contacting turbid wastewater to cellulose ester fibrets under conditions sufficient to flocculate the contaminant to form a treatment suspension, and then (b) separating the flocculants from the treatment suspension to provide a clarified wastewater.
