Abstract
The design and implementation of membrane bioreactor (MBR) pilot plant was performed in order to treat municipal wastewater derived from the Súria municipality (Catalonia, Spain) wastewater treatment plant. Two submerged membrane configurations (flat sheet and hollow fibre) in MBR pilot plant were used for this purpose. The influent and effluents were monitored and controlled in order to ensure the achievements of the highest quality determined by Spanish legislation for water reuse. The Remosa company interest was focused in pilot plants applications for the small urban areas. Taking into account that the level of control and maintenance of this small plant can be lower than recommended, the start-up was performed under less favourable conditions without any sludge seed. After 8-months of continuous operation, the physico-chemical and microbial parameters of both MBR configurations achieved the water quality specifications defined for urban service, agricultural and recreational uses. The flat sheet configuration reported easier operation and maintenance (chemical cleaning frequency) compared to the hollow fibre one.
