Treatment of dairy effluents by electrocoagulation using aluminium electrodes

Cetylpyridinium removal using phosphate-assisted electrocoagulation, electroreduction and adsorption on electrogenerated sorbents

“…2 and look like the titration curve of an acid by a base showing a pseudo equivalent point at about 250 min. Analogous pH variation has been already observed during EC of H 3 PO 4 solutions [24]. In this case, the equivalence point corresponds to the total transformation of phosphoric acid into aluminum phosphate.…”

<bold>The efficiency of electrocoagulation using aluminum electrodes</bold>i<bold>n treating wastewater from a dairy industry</bold>

“…The EC showed low removal efficiency of TS, VTS, FTS and FSS, on average 35.1; 39.3; 14.5 and 47.6% respectively. COD reduction was found to be significantly lower than previously reported by Tchamango et al (2010) and KUSHWAHA et al (2010) that used artificial wastewater l. It was obtained a removal efficiency of 57% of COD in this study, in contrast to the high value, 98%, obtained by SENGIL & OZACAR (2006) where the suspended solid content in effluent was high. In the study presented here, the effluent had a high concentration of dissolved solids, representing 80% of total solids.…”

Remediation of Feedlot Nutrients Runoff by Electrocoagulation Process

“…In the past, limited studies on the use of electrocoagulation were performed on livestock wastewater including swine (Bejan et al, 2007;Cho et al, 2010;Laridi et al, 2005;Rahman and Borhan, 2014), dairy (Bensadok et al, 2011;Şengil, 2006;Tchamango et al, 2010;Yavuz et al, 2011), slaughter house wastewater (Bazrafshan et al, 2012), industrial effluents (Ali and Yaakob, 2012;Basha et al, 2008), pharmaceutical wastewater (Yi-zhong et al, 2002), agroindustry and textile dye wastewater (Merzouk et al, 2009). However, until today, electrocoagulation was not use to treat feedlot runoff.…”
