Effect of operating conditions on the chemical phosphorus removal using ferric chloride by evaluating orthophosphate precipitation and sedimentation of formed precipitates in batch and continuous systems
(Elsevier Science, 2012-10-15)
Chemical phosphate removal by Fe(III) involves the precipitation of ferric phosphate and subsequent sedimentation of Fe-P particles. Physical-chemical factors that affect the phosphorus (P) precipitation are well known; ...
Factors affecting the degradation of Biphenol A by activated sludge
(Lambert Academic Publishing, 2016)
Bisphenol A (BPA) has been described as a estrogenic compound.However, it is used in the production of polycarbonate, epoxy resins and otherplastics. Mixed microbial cultures, such as activated sludge, have been proposed ...
Effect of sewage sludge ash on mechanical and microstructural properties of geopolymers based on metakaolin
(2019-04-10)
This paper explored the effect of sewage sludge ash (SSA) on the mechanical and microstructural properties of geopolymers based on metakaolin (MK) involving two different SiO 2 /Na 2 O molar ratios (0.8 and 1.6), two ...

Biodegradation of bisphenol A and its metabolic intermediates by activated sludge: Stoichiometry and kinetics analysis
(Elsevier, 2016-01)
Bisphenol A (BPA) has been described as a estrogenic compound. However, it is used in the production of polycarbonate, epoxy resins and other plastics. Mixed microbial cultures, such as activated sludge, have been proposed ...
Fertilization using sewage sludge in unfertile tropical soils increased wood production in Eucalyptus plantations
(Elsevier B.V., 2017-12-01)
Fertilization of Eucalyptus plantations using sewage sludge on unfertile tropical soils represents an alternative to using mineral N and P fertilizers. A 44-month field experiment was conducted to study the effects of ...
Tratamento de borra de petróleo com sistemas microemulsionados
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2013-07-25)
During the storage of oil, sludge is formed in the bottoms of tanks, due to
decantation, since the sludge is composed of a large quantity of oil (heavy petroleum
fractions), water and solids. The oil sludge is a complex ...
Biodegradation of bisphenol-A (BPA) in activated sludge batch reactors: Analysis of the acclimation process
(Elsevier, 2013-11-28)
In this work the effect of (a) the sludge age (SA) and the acclimation strategy on the acclimation process of activated sludge (AS) to bisphenol A (BPA), (b) the presence of biogenic substrates on the degradation of BPA, ...
