Study into a new carrier used moving bed biofilm reactor (MBBR) from waste glasses for domestic wastewater treatment

Abstract

Moving bed biofilm reactor (MBBR) was highly appreciated for wastewater treatment in recent years. In Vietnam, most of carriers for MBBR which was imported had a high efficiency in treatment; however, their price and durability in extreme weather was the great concern. Glass-based pumice was studied as a MBBR carrier, and the resulting material had the specific weight of 9.9 kN/m3 , porosity of 96%, large surface area of 0.35-0.66 m2 /g (the result obtained by BET method). These characteristics of glass-based pumice could be an interesting option for biofilm reactor for wastewater treatment plant.
