Title: Corrosion investigations on secondary treated paper mill effluents

Abstract: Purpose – This paper aims to report on corrosivity of secondary-stage paper mill effluent and corrosion performance of stainless steels. Design/methodology/approach – For this purpose, immersion test and electrochemical polarization tests were conducted in mill and synthetic effluent to evaluate the uniform and localized corrosion. Findings – Corrosivity of mill effluent has been compared with synthetic and primary-stage effluent of the same mill. It is observed that anions present in them, viz. SO<inf>4</inf> ¯, PO<inf>3</inf>4¯, NO<inf>2</inf> ¯ and NO<inf>3</inf> ¯, impart inhibition, whereas Cl¯ and chlorophenols enhance the corrosivity of the effluent. The overall effect of various components was reduction in corrosivity of secondary mill effluent. Originality/value – These observations can be useful for material selection and helpful in corrosion mitigation in paper mill effluent treatment plants. © 2015, Emerald Group Publishing Limited.
