Colloidal organic fibrils in surface waters [electronic resource] : electron-optical characteristics, activities and chemical estimates of abundance / Gary G. Leppard. Burlington, Ont. : National Water Research Institute, [1996]. 25, [4] p. : ill. NWRI contribution ; 96-151 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "This invited review paper presents suggestions for engineering applications of colloidal organic fibrils, discovered by NWRI scientists in 1977 to be an abundant component of surface waters. These are the same fibrils shown recently by NWRI scientists to be an important component of suspended flocs in engineered water treatment facilities. The fibrils are defined chemically and morphologically in this review, accompanied by the current knowledge of their activities in natural waters. Means to isolate and characterize the fibrils are presented, along with techniques for quantifying them. Suggestions for engineered manipulations are offered for the purpose of producing flocs which might have optimal properties in water decontamination systems"-- Management perspective.
