3. Contents of macronutrients and growth of ‘BRS Marataoã’ cowpea fertigated with yellow water and cassava wastewater
Resumo O uso agrícola de águas amarelas associadas à manipueira é uma técnica sustentável, uma vez que possibilita a redução de custos com a aquisição de fertilizantes industrializados e minimiza a poluição ambiental ocasionada pela destinação final inadequada desses efluentes. Neste contexto, objetivou-se com este trabalho avaliar os teores de

4. Optimization of parameters technological to process tucupi and study of product stability
Abstract Tucupi is a product obtained from the fermentation and cooking of cassava root wastewater which is widely used in the popular cuisine of the North region of Brazil. This study employed an experimental design to select tucupi processing (fermentation and cooking times) as a function of residual cyanidric acid content and assess the stability of the

5. METHANE PRODUCTION FROM CASSAVA STARCH WASTEWATER IN PACKED-BED REACTOR AND CONTINUOUS FLOW
ABSTRACT The aim of this study was to evaluate the behavior of an anaerobic reactor of packed-bed and continuous flow, in relation to the biogas and methane production and the removal of organic load, from the wastewater of cassava starch extraction. For this purpose, were tested, in a reactor with a useful volume of 2.82 L and support mean of polypropylene

6. OPTIMIZATION OF ANAEROBIC TREATMENT OF CASSAVA PROCESSING WASTEWATER
ABSTRACT The main contribution of this research is to optimize the operating conditions of an anaerobic reactor applied to the treatment of wastewater from cassava starch production. A 20-L anaerobic reactor was used, operating in a batch system, with temperature control. Temperature and inoculum total volatile solids (TVSi) were controlled for evaluation of

7. HYDROGEN PRODUCTION AND PERFORMANCE OF ANAEROBIC FIXED-BED REACTORS USING THREE SUPPORT ARRANGEMENTS FROM CASSAVA STARCH WASTEWATER
ABSTRACT Fixed-bed reactors have been considered promise alternatives for hydrogen production due to their simple construction and increase in the biomass retention. The purpose of this study was to investigate the biological production of hydrogen in anaerobic fixed-bed reactors with cassava starch wastewater used as substrate. Different support materials a

8. Cassava processing wastewater as a platform for third generation biodiesel production
ABSTRACT This study aimed to evaluate third generation biodiesel production by microalgae Phormidium autumnale using cassava processing wastewater as a platform. Experiments were performed in a heterotrophic bubble column bioreactor. The study focused on the evaluation of the bioreactor (batch and fed-batch) of different operational modes and the analysis of

9. Aerobic cyanide degradation by bacterial isolates from cassava factory wastewater
Ten bacterial strains that utilize cyanide (CN) as a nitrogen source were isolated from cassava factory wastewater after enrichment in a liquid media containing sodium cyanide (1 mM) and glucose (0.2% w/v). The strains could tolerate and grow in cyanide concentrations of up to 5 mM. Increased cyanide levels in the media caused an extension of lag phase in

10. Biohydrogen production from cassava wastewater in an anaerobic fluidized bed reactor
The effect of hydraulic retention time (HRT) and organic loading rate (OLR) on biological hydrogen production was assessed using an anaerobic fluidized bed reactor fed with cassava wastewater. The HRT of this reactor ranged from 8 to 1 h (28 to 161 kg COD/m³-d). The inoculum was obtained from a facultative pond sludge derived from swine wastewater treatment

11. Tratamento de efluente de fecularia em reator anaerÃbio tubular horizontal piloto com meio suporte e agitaÃÃo / Treatment of cassava starch extraction effluent in a one phase Tubular horizontal reactor with support medium and agitation
As fecularias produzem diariamente um grande volume de manipueira, que, estabilizada em lagoas, desperdiÃa a energia do biogÃs e polui a atmosfera. Para contribuir com a reversÃo dessa realidade, desenvolveu-se esta pesquisa de tratamento de manipueira em reator anaerÃbio horizontal piloto com alimentaÃÃo contÃnua. O reator foi implantado numa fecular

12. Tratamento de Ãgua residuÃria de fecularia em reator anaerÃbio com leito fixo de pedras de calcÃrio dolomÃtico / Starch wastewater treatment in anaerobic reactor containing Dolomitic limestone
The cassava processing for starch or flour production generates some wastewater (manipueira) with high organic load and toxic compounds, which cause environmental degradation. In the western Paranà region, there are several starch factories, so its waste generation is a concern for the correct treatment and disposal. Thus, anaerobic reactors are a cost-effe
