Flocculation - an overview | ScienceDirect Topics

Flocculation. Flocculation is cheap, simple, and feasible to harvest large volume of microalgae culture [44,67,68,69]. There are several flocculation types such as physical, chemical, and biological methods. Generally, flocculation is applied as a preconcentration step for harvesting of microalgal cells.

Biopolymer-based flocculants: a review of recent technologies

Organic flocculation is the most common secondary concentration method when a protein solution such as beef extract or skimmed milk is used as the eluant. This method was first described by Katzenelson et al. 85 and involves lowering the pH of the eluant to 3.5 in order to produce protein precipitates. The virus-containing floc can subsequently

Flocculation Harvesting Techniques for Microalgae: A Review

There is a sigmoidal relationship between increase in cultural pH and flocculation efficiency for the freshwater alga Ettlia sp. YC001. The harvesting efficiency is very low at ~11% in the pH range of 6.5–8.5, while it dramatically increases to 83% and 94% with increase in pH to 10.5 and 12.5, respectively [ 37 ].

Flocculation - Wikipedia

Flocculation is synonymous with agglomeration and coagulation / coalescence. Basically, coagulation is a process of addition of coagulant to destabilize a stabilized charged particle. Meanwhile, flocculation is a mixing technique that promotes agglomeration and assists in the settling of particles.

Coagulation and Flocculation in Water and Wastewater

Material for this article was largely taken from reference 1. Coagulation and flocculation are essential processes in various disciplines. In potable water treatment, clarification of water using coagulating agents has been practiced from ancient times. As early as 2000 BC the Egyptians used almonds smeared around vessels to clarify river water.

Flocculation : types, uses and treatment - Unacademy

What is flocculation? Flocculation is the chemical process in which the colloidal particles come out of suspension to sediment down in flake or floc spontaneously or by adding clarifying agents. This process is different from precipitation as in a liquid, the colloidal particles in flocculation are suspended.
