1. Additions and Corrections
The degradation of a pharmaceutical mixture (gemfibrozil, hydrochlorothiazide and naproxen) by TiO2/UV-A in different aqueous matrices was evaluated. The matrix components affected the operational conditions, rate constants, and removal efficiency of the pharmaceuticals, as well as toxicity. For sewage treatment plant effluent, a TiO2 concentration three-fol

3. Use of Coffee Capsules as Support Material in Upflow Anaerobic Fixed Bed Reactors
Abstract The aim of this work is to evaluate the performance of upflow anaerobic fixed bed reactors filled with espresso coffee capsules to treat sanitary sewage. Three reactors (R1, R2 and R3) were constructed in blue PVC pipes measuring 30 cm height and 150 mm diameter and filled with coffee capsules made of aluminum and plastic. The sewage from the pre-tr

4. Remoção de algas em um sistema de biofiltros submersos
RESUMO Esta pesquisa propôs o desenvolvimento de um sistema de biofiltros submersos (SBS), modificados com base na configuração de filtros de pedra, visando ao pós-tratamento do efluente de lagoas de estabilização, inicialmente para a remoção de algas. Foram implantados 2 conjuntos de biofiltros submersos para captar esgoto tratado de duas diferentes

6. Ozonation improves physical attributes in domestic sewage effluent
Resumo O Sistema de Zona de Raízes (SRZ) é uma opção natural de tratamento de efluentes amplamente estudado em todo o mundo, sendo uma tecnologia baseada em processos físicos, químicos e biológicos. No entanto, existem alguns atributos no efluente que ocasionalmente não são eliminados pelo SZR. Nesse contexto, o uso do ozônio pode contribuir para a

7. Use of chitosan in the remediation of water from purification of biodiesel
Abstract This article evaluates the efficiency of the degradation of pollutants present in water from the purification of biodiesel, characterized by high content of chemical oxygen demand (COD), suspended solids (SS), oils and greases, methanol, soap, and glycerol. The treatment process proposed was of the photo-Fenton type using iron immobilized in chitos

8. Dissolved Air Flotation for Fiber Removal from Clear Water
ABSTRACT We investigated the use of dissolved air flotation (DAF) to treat clear water effluent from the paper industry in order to remove fibers. The dosage of polyaluminium chloride (PAC) was varied in the following concentrations: 0, 75, 100, 125, 150 and 175 mg/L; as well as bubble rise velocity of 18 and 9 cm/min for two types of paper wastewater: print

9. SUPPLEMENTATION OF NUTRIENTS FOR TABLE BEETS BY IRRIGATION WITH TREATED DAIRY EFFLUENT
ABSTRACT: This study was conducted to evaluate the nutritional status of table beet plants cultivated in a greenhouse irrigated with treated dairy effluent at different irrigation depths. The experimental design used was a randomized block in a 3 x 3 + 1 factorial arrangement with four replications and conducted in a greenhouse. The treatments consisted of t

10. 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

11. Tratamento de esgoto sanitário pelo sistema zona de raízes utilizando plantas de bambu / Sewage treatment by root zone system using bamboo plants.
This study aimed to evaluate the efficiency of three species of bamboo (Guadua angustifolia, Phyllostachys aurea and Phyllostachys bambusoides) in the sanitary sewage treatment, with a vertically downward sub-surface flow root zone system, in Goiânia, GO, Brazil. Sewage from a university was applied to asbestos cement water tanks with 1,000 liters volume ca
