Study on Invalidation and Regeneration of TGV Manganese Sand Filter

Abstract:

Because the manganese removal ability of TGV manganese sand filter decreases a lot in A water plant, in this study full-scale experiment and electron microscopy analysis were conducted to evaluate the actual manganese removal ability and explore a method for regeneration in production. The results showed that the manganese sand had lost the manganese removal ability, and the principle of manganese removal was physical adsorption. The maximum adsorptive capacity was measured to be 7.2 (mg manganese ions)/ (g manganese sand) through bench scale experiments, that meant the sand filter could work effectively for 7-8 months, and then the manganese sand would become invalidate. It was recommended to dip 1 litre manganese sand in 500 ml sodium hypochlorite with 0.35% effective chlorine to achieve regeneration, and the cost was acceptable.
