This indicates an optimum dosage range of alum for effective coagulation of algal cells, due to the conceivable isoelectric point between the alum and algal cells.

Coagulation is a chemical process that involves neutralization of charge whereas flocculation is a physical process and does not involve neutralization of charge. The coagulation-flocculation process can be used as a preliminary or intermediary step between other water or wastewater treatment processes like filtration and sedimentation. With the many treatment and water quality problems associated with algae, this study presents its findings on: coagulation conditions, the utility of on-line in-vivo fluorescence, dissolved oxygen and pH measurements; effectiveness of conventional treatment; and effects of potassium permanganate preoxidatiion. Recommendations and treatment strategies are presented as well. Effect of coagulation on nutrient and light limitation of an algal bloom George A. Jackson and Steve E. Lochmann Department of Oceanography, Texas A&M University, College Station Abstract Coagulation is the formation of large particles ‘from multiple collisions of smaller ones. BecauseCited by: Its removal effects on algal cells and dissolved organics in water were studied. After mixing, coagulation, and magnetic separation, the flocs obtained from the magnet surface were examined by SEM. Treated samples were withdrawn for the content determination of chlorophyll-a, turbidity, chemical oxygen demand (COD), total nitrogen, and total Cited by:

  This research investigated the feasibility of changing waste into useful materials for water treatment and proposed a coagulation–magnetic separation technique. This technique was rapid and highly effective for clearing up harmful algal blooms in freshwater and mitigating lake eutrophication. A magnetic coagulant was synthesized by compounding acid-modified fly ash with magnetite (Fe3O4).Cited by: The results show two effects of coagulation on the growth model. Loss of dividing cells to coagulating particles can occur when algal cells are growing at a fairly constant rate, placing a cap on the concentrations that algae can achieve. The second effect is enhancement of vertical particle flux from the surface mixed layer in by: Using alum as an element of a comprehensive watershed and lake management program will often be needed to achieve meaningful results in a timely and cost-effective manner. Considering that alum applications may be effective for 5 to 15 years (Welch and Cooke ), as well as the fact that watershed phosphorus control seldom goes far enough.   The effects of ozone and chlorine on algae were examined with respect to cell surface characteristics, lysis and coagulation ability. Two algae were studied: a green alga (Scenedesmus quadricauda) and a diatom (Cyclotella sp.).Cell properties were characterized using scanning electron micrographs, particle size distributions and electrophoretic mobility by:
