摘要

Abstract

The impact of harmful algal blooms (HABs) on public health and related economics have been increasing in many coastal regions of the world. Sedimentation of algal cells through flocculation with clay particles is a promising strategy for controlling HABs. Previous studies found that removal efficiency (RE) was influenced by many factors

including clay type and concentration

algal growth stage

and physiological aspects of HAB cells. To estimate the effect of morphological characteristics of the aggregates on HAB cell removal

fractal dimensions were measured and the RE of three species of HAB organism

Heterosigma akashiwo

Alexandrium tamarense

and Skeletonema costatum

by original clay and modified clay

was determined. For all HAB species

the modified clay had a higher RE than original clay. For the original clay

the two-dimensional fractal dimension (D 2) was 1.92 and three-dimensional fractal dimension (D 3) 2.81

while for the modified clay

D 2 was 1.84 and D 3 was 2.50. The addition of polyaluminum chloride (PACl) lead to a decrease of the repulsive barrier between clay particles

and resulted in lower D 2 and D 3. Due to the decrease of D 3

and the increase of the effective sticking coefficient

the flocculation rate between modified clay particles and HAB organisms increased

and thus resulted in a high RE. The fractal dimensions of flocs differed in HAB species with different cell morphologies. For example

Alexandrium tamarense cells are ellipsoidal

and the D 3 and D 2 of flocs were the highest

while for Skeletonema costatum

which has filamentous cells

the D 3 and D 2 of flocs were the lowest.
