Abstract:

A escassez das fontes de fósforo e o alto consumo de energia associado à produção de fertilizantes nitrogenados serão problemas que deverão ser enfrentados no futuro. A recuperação de nutrientes das águas residuárias na forma de estruvita tem sido considerada como uma alternativa para atenuar estes problemas. Na América Latina, a produção de estruvita a partir de esgoto ainda não é uma tecnologia bem conhecida e, portanto, a finalidade deste trabalho é contribuir com uma melhor compreensão dos fenômenos envolvidos. Para isso, a pesquisa foi dividida em três etapas: 1) produção de estruvita a p

Abstract:

Nutrients present in digested animal waste can be utilized for algae cultivation under suitable conditions. Algal growth, however, depends on the chemical forms and speciation of these nutrients. In this study a chemical equilibrium model was first used to describe nutrient speciation and predict conditions that enhance the solubility of nutrients in anaerobic digester effluent. Dilution with water and separation of large particulates greatly improved nutrient availability and light penetration - conditions favorable for algal cultivation. Algae growth was tested using three strains - Scenede

Abstract:

Current abattoir wastewater treatment options involving aerobic and anaerobic digestion systems are relatively inefficient in reducing the inorganic nutrient load (i.e. ammonium and phosphate) of the effluent. With anaerobic lagoons favoured in Australia resulting in large land footprint, loss of environmental and economic value in the form of water and nutrient recovery. The cultivation of microalgae on undiluted anaerobic digestion abattoir effluent (ADAE) offers many potential benefits such as the bioremediation of waste nutrients typically found in the effluent and simultaneous production

Thesis (MSc)--Stellenbosch University, 2000.<br>ENGLISH ABSTRACT: A severely polluted industrial effluent is generated by the local gelatinmanufacturing industry. Due to increasingly stringent restrictions on discharge qualities enforced by the National Water Act of 1998 and National Environmental Management Act of 1998, as well as increasing trade-effluent charges implemented via the Local Municipal Bylaws, the industry is compelled to consider a system to pre-treat the polluted effluent. A study was undertaken to examine the viability of anaerobic treatment of the gelatin-manufacturin

Abstract:

Increasing charges by the private utilities for the treatment of industrial waste water are making on-site effluent treatment more attractive. On-site anaerobic digestion is increasingly being used by food processing factories as a cost effective solution to waste liquid waste disposal. Discharge of treated effluent to sewer or water course requires compliance to a maximum admissible concentration (MAC) value, therefore, there is a need for careful control of on-site waste water treatment. This research investigates the treatment of effluent from instant coffee production. This results in a li

Afin d’assurer un développement pérenne de la filière de méthanisation, il est donc nécessaire de comprendre d’abord tous ces phénomènes d’altération pour ensuite proposer des solutions durables pour les matériaux de construction des digesteurs.

Abstract:

Sustainability of resources such as energy, water and waste have become important drivers in our current economy. For large industries that are water and energy intensive like pulp and paper (P&P) mills, this is a specifically relevant issue. The large and heterogenous volumes of effluents in P&P mills make it a difficult task to properly treat before discharge. Anaerobic digestion is an efficient wastewater technology that cleans the effluent, reduces wasted sludge and simultaneously produces methane that can be further used as energy.

Abstract:

Este trabalho foi desenvolvido no município de Nova Redenção, localizado na região da Chapada Diamantina no estado da Bahia, nordeste brasileiro. Nesse município é grave o quadro de saneamento ambiental, assim como em outros do interior do Brasil. A falta de recursos financeiros e humanos é fator que dificulta a resolução desse problema. Acredita-se que estudos e aprimoramentos de tecnologias simplificadas de coleta e tratamento de esgoto doméstico que superem essas dificuldades estão em consonância com as peculiaridades dessas localidades e são, atualmente, tópicos importantes para pesquisa.

Anaerobic digestion is a treatment process applied to organic solid waste and wastewater carried out by microorganisms under anaerobic conditions (without oxygen). In addition to treating wastewater, this process’s main product is biogas, a mixture of methane and carbon dioxide. On this assumption, it is easy to understand how this biological process can be an asset in the fight against climate change, as it not only produces renewable energy, but also contributes to reducing the negative impacts resulting from the discharge of organic waste into the environment.
