Thermax offers integrated water management solutions including sewage treatment. Their fluidized aerobic biofilm (FAB) reactor uses floating media to support biomass growth, treating sewage in an attached film with advantages over conventional activated sludge processes. The modular FAB system can achieve over 90% reductions in both BOD and COD using two reactors in series with countercurrent air-wastewater flow.
