1. Distribuição e biodisponibilidade do níquel aplicado ao solo como NiCl2 e Biossólido. / Distribution and bioavailability of nickel applied to soil as nicl2 and biossólid.
The role of Nickel in soils under the application of biossolids is still not very well known. The objectives of this study were to investigate the influence of total Nickel and organic carbon content, and soil pH, in the Nickel distribution among soil fractions and the bioavailability of the metal to lettuce. Three incubation pot trials were carried out in g

2. Thermal drying of wastewater sludge: determination of equilibrium moisture. / Secagem térmica de lodos de esgoto: determinação da umidade de equilíbrio.
The study presents the main aspects of a thermal drying operation of the sludge produced by wastewater treatment plants, the types of equipment likely to be used for this purpose and the sorption behavior of the water contents by the dry material when in contact with the air. The thermal drying operation is an alternative to reduce the weight and volume of t

3. A situação brasileira dos biossolidos
The wastewater treatment process generate several subproducts, one of them is the sewage sludge, which has a higher operational cost of treatment, transportation and final disposal.Biosolids is a new word assigned to the stabilized sludge generated in the wastewater treatment plants, in order to be recyc1ed, having a more useful final disposal, such as apply
