Abstract |
Electron micrographs of the colloidal fraction in the effluent from an activated sludge waste water-treatment plant show fragments of bacterial cell walls as the dominant material. Viruses, phage, flagella, and other cellular debris are present to a lesser degree. Clarification by membrane filtration, or by flocculation with lime or ferric chloride, removes most of the colloidal material of cellular origin. (Author) |
