Improved algal harvesting using suspended air flotation.
Current methods to remove algae from a liquid medium are energy intensive and expensive. This study characterized algae contained within a wastewater oxidation pond and sought to identify a more efficient harvesting technique. Analysis of oxidation pond wastewater revealed that algae, consisting primarily of Chlorella and Scenedesmus, composed approximately 80% of the solids inventory during th...
متن کاملCritical evaluation and modeling of algal harvesting using dissolved air flotation.
In this study, Chlorella zofingiensis harvesting by dissolved air flotation (DAF) was critically evaluated with regard to algal concentration, culture conditions, type and dosage of coagulants, and recycle ratio. Harvesting efficiency increased with coagulant dosage and leveled off at 81%, 86%, 91%, and 87% when chitosan, Al(3+) , Fe(3+) , and cetyl trimethylammonium bromide (CTAB) were used at...
متن کاملThe Effect of Superficial Feed Velocity on the Column Flotation Recovery in Comparison with the Conventional Flotation Cells
Flotation is the most important process for concentrating mineral ores. This process may occur in any vessel such as column flotation, which has been used widely during the last decade and the conventional flotation cells. The effect of superficial feed velocity on the copper recovery was investigated using pilot-scale column flotation of "Sarcheshmeh Capper Complex". The results were compa...
متن کاملFoam consolidation and drainage.
A theoretical model of foam as a consolidating continuum is proposed. The general model is applied to foam in a gravity settler. It is predicted that liquid drainage from foam in a gravity settler begins with a slow drainage stage. Next, a stage with faster drainage occurs where the drainage rate doubles compared to the initial stage. The experiments conducted within the framework of this work ...
متن کاملHarvesting of algae by froth flotation.
A highly efficient froth flotation procedure has been developed for harvesting algae from dilute suspensions. The method does not depend upon the addition of flotants. Harvesting is carried out in a long column containing the feed solution which is aerated from below. A stable column of foam is produced and harvested from a side arm near the top of the column. The cell concentration of the harv...
