1. Treatment of pulp and paper bleaching effluents by means of ozone advanced oxidation processes / Tratamento de efluentes do branqueamento da polpa celulósica por processos oxidativos avançados baseados em ozônio
The impact of ozone oxidation in transforming high molecular weight (HMW) organic compounds in order to improve the biodegradability of pulp and paper effluents was investigated under different ozone doses. The experiments were conducted uppon a primary treated effluent and an alkaline bleach plant effluent taken from two pulp mills. The effluents were inves

2. Rhizospheric microorganisms and arbuscular mycorrhiza in soil from a petrochemical waste landfarming system. / Microbiota RizosfÃrica e Micorriza Arbuscular em Solo de "Landfarming" de ResÃduos PetroquÃmicos.
In the petroleum industrialization a great volume of different toxic residues is generated. Because of these waste environmental hazards they need to be adequately treated before final disposition in the environment. These wastes are usually treated by landfarming systems, but this technique has only relative success, since it doesn t completely remove all c
