1. A methodology for optimising the removal of cyanobacteria cells from a brazilian eutrophic water
This work is concerned with optimizing the performance of the coagulation process in terms of the removal of intact cyanobacteria cells and saxitoxins (STX). The evaluation has been carried out through bench-scale jar tests to construct coagulation diagrams for aluminium sulphate, polyaluminium chloride (PACl) and ferric chloride. The test water was taken fr

2. Remoção de saxitoxinas por meio de oxidação com cloro / Remoção de saxitoxinas por meio de oxidação com cloro
A eutrofização artificial de reservatórios pode ter como consequência a ocorrência de florações de cianobactérias tóxicas e, no Brasil, é crescente o número de relatos de florações da espécie Cylindrospermopsis raciborskii produtora de saxitoxinas. O tratamento constituído por coagulação, floculação, sedimentação e filtração não remov

3. Removal of the organic contaminants β-estradiol and saxitoxins (STX, Neo-STX and dc-STX) by nanofiltration : bench scale / Remoção dos contaminantes orgânicos B-estradiol e saxitoxinas (STX, Neo-STX e dc-STX) por meiom de nanofiltração : avaliação em escala de bancada
The aim of work was to investigate the removal of β-estradiol and saxitoxins (STX, dc- STX and Neo-STX) by nanofiltration. These contaminants were selected due to its growing detection in drinking water reservoirs and their potential risk to human health, even at low concentrations. According to the literature, these substances are only poorly removed b

4. Dinâmica de populações de cianobactérias em reservatório eutrofizado no semi-árido nordestino brasileiro.
The Armando Ribeiro Gonçalves reservoir, located in the semi-arid of the Rio Grande do Norte (06o08 S ; 37o 07 W), in Northeast Brazil, represents 68% of the total surface water accumulated in the state. The reservoir, with maximum volumetric capacity of 2.4 x 109, provides 400 thousands habitants and also is destined to irrigation, leisure and fishing. It
