摘要: VILLEGAS-MENDOZA, I. E., MARTIN-DOMINGUEZ, A., PEREZ-CASTREJoN, S. & GELOVER-SANTIAGO, S.L. Electrocoagulation to Remove Silica from Cooling Towers Water. Water Technology and Sciences (in Spanish). Vol. V, No. 3, May-June, 2014, pp. 41-50. This paper presents the results of a study carried out about effect water quality on removal dissolved silica using an electrocoagulation process with aluminum electrodes. is found in replacement (RW), usually known as make up water, cooling tower blowdown (CTBW). Tests were conducted small pilot scale (~2 lmin-1) continuous flow device. The treatment train consisted (EC), flocculation, sedimentation sand filtration. Two distinct RW two CTBW different physicochemical characteristics studied. response variables analyzed were: efficiency remove (ratio mgl-1 dosed Al3+/mgl-1 SiO 2 removed), Al3+, hydraulic head loss throughout electrochemical reactor voltage. cost for four types discussed. ratio Al3+ /mgl-1 removed ranged 1.09 ± 0.06 1.33 0.05 when treating 0.85 0.1 CTBW. consumption costs energy, chemicals electrodes US$ 0.52 0.74 m-3, was approximately US$0.53 m-3
