Precontrol of algae-induced black blooms through sediment dredging at appropriate depth in a typical eutrophic shallow lake

Effects of sediment dredging on internal phosphorus: A comparative field study focused on iron and phosphorus forms in sediments

“…Previously, many dredging projects generated positive effects on nutrient control in lake systems in short term, but negative effects were observed in a long run (Ruley and Rusch, 2002;Zhong and Fan, 2007;MACTEC, 2008). Additionally, effects of dredging can be affected by the dredging depth (Liu et al, 2015). The mechanisms underlying the observed effects on nutrients cycling remained puzzling.…”

In situ enclosure experiments on the occurrence, development and decline of black bloom and the dynamics of its associated taste and odor compounds

“…Moreover, DMS, DMTS and ␤-cyclocitral simultaneously reached extremely high levels, with maxima of 62.33, 12.41 and 1.37 g L −1 , respectively. Liu et al (2015) suggested that sediment dredging at an appropriate depth could suppress the occurrence of black bloom but could not suppress the offensive odor. Feng et al (2014) suggested that sulfide-reducing bacteria (SRB) and protein are the principal biological and organic factors, respectively, that contribute to the occurrence of black bloom.…”

Effectiveness and Mode of Action of Calcium Nitrate and Phoslock® in Phosphorus Control in Contaminated Sediment, a Microcosm Study

“…Sediment dredging is a simple way to remove internal nutrients but the outcomes were found controversial (Jing et al 2013;Liu et al 2015;Zhang et al 2010). In addition, high cost and problems associated with the treatment and disposal of the dredged sediment prevent the wide application of sediment dredging (Murphy et al 1999).…”
