Hacking biofilm developed in a structured-bed reactor (SBRRIA) with integrated processes of nitrogen and organic matter removal
(2021-01-01)
Biomass samples from a structured-bed reactor subjected to recirculation and intermittent aeration (SBRRIA) were analyzed to investigate the bacterial community shift along with the changes in the C/N ratio. The C/N ratios ...
A new device to select carriers for biomass immobilization and application in an aerobic/anaerobic fixed-bed sequencing batch biofilm reactor for nitrogen removal
(2016-12-01)
This study proposes a new approach to selecting a biofilm carrier for immobilization using dissolved oxygen (DO) microsensors to measure the thickness of aerobic and anaerobic layers in biofilm. The biofilm carriers tested ...
Rates of CO2 removal by a Aphanothece microscopica Nageli in tubular photobioreactors

Tratamento de efluente de restaurante universitário por wetland construído de fluxo vertical com leito parcialmente saturado
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia AmbientalUTFPR, 2016-12-01)
Vertical flow constructed wetlands are an attractive alternative for wastewater treatment due to its potencial in descentralization systems, low implantantion, operation and maintenance costs. This study aimed to evaluate ...
Biological Cr(VI) removal coupled with biomass growth, biomass decay, and multiple substrate limitation
(Pergamon-Elsevier Science Ltd, 2011-05)
In this work, a mathematical model for the biological reduction of Cr(VI), carbon and nitrogen sources consumption, and biomass growth under fully aerobic conditions was developed. The model comprises three types of aerobic ...
Nitrogen removal in a sequencing batch biofilm reactor with liquid circulation: Effect of feed strategy and carbon source in the denitrifying step
(ASOC QUIMICOS, 2010)
Ammonium nitrogen removal from a synthetic wastewater by nitrification and denitrification processes were performed in a sequencing batch biofilm reactor containing immobilized biomass on polyurethane foam with circulation ...
