WebFlocculation has been chosen as an optimized method for harvesting microalgae at a low cost, and different flocculation technologies are also developed. Flocculation is a … WebFlocculation is the process where multiple particles are bridged together to form flocs or flakes. Flocculants added to stormwater runoff during flocculation the process enhance the binding effect of multiple particles …
WebFlocculation is further influenced by factors such as salinity and pH of the water. When flocs grow, they not only capture smaller flocs that settle more slowly, but also other suspended sediments, such as detritus, silt and fine sand. Frequent encounters between sediment particles are important for floc growth.
