Abstract
Low-cost ceramic membrane was evaluated on a bench scale, in the separation process of blue methylene dye. Raw materials were characterized by XRD and XRF. The ceramic membrane was produced by dry uniaxial compaction and characterized by XRD, porosity and permeability with pure water. The membrane contains a composition of 65.00 % chocobofe clay, 5.00 % corn starch kaolin, 20.00 % magnesite concentrate and 5.00 % corn starch and sintering temperature of 650 °C. The initial blue methylene dye concentration was 50 mg/L, pressure 2 bar, 25 °C. The low-cost ceramic membrane was effective in separating blue methylene dye, with porosity of 53 % and average pore size of 0.48 µm, as well as pure water flow of 520 L/m2.h. The blue methylene dye rejection was 100.00 %. The membrane reuse demonstrated good performance after 15 cycles. A preliminary costs analysis of the production for low-cost membrane was carried out and the value found was 233.55 $/m2.
