Evaluation of Organic Load Measurement Techniques in a Sewage and Waste Stabilisation Pond
A Demanda Bioquímica de Oxigênio (DBO) e a Demanda Química de Oxigênio (DQO) são os principais indicadores rotineiramente utilizados para avaliação de carga orgânica em matrizes de interesse ambiental. Nesse contexto, avaliações da possibilidade de substituição das testes de DBO e DQO por medidas de Carbono Orgânico Dissolvido (COD) são apresentadas para diferentes águas residuárias. Para eflue...
متن کاملMicrobial Phosphorus Removal in Waste Stabilisation Pond Wastewater Treatment Systems
Waste Stabilisation Ponds (WSPs) are characterised by low phosphorus (P) removal capacity. Heterotrophic bacteria are principal microbial agents in WSPs in addition to algae. As treatment proceeds in WSPs, algal growth increases and pH rises, this has lead to believe that P removal is mainly through sedimentation as organic P algal biomass and precipitation as inorganic P. In activated sludge t...
متن کاملPhysical and hydrodynamic characteristics of a dairy shed waste stabilisation pond system.
Waste stabilization pond systems are widely used to treat animal wastes under highly variable hydraulic loading regimes. These systems have received limited research attention with regard to their hydrodynamic behaviour and the potential impact of shock hydraulic loading on their performance. In this study a two-stage dairy shed waste stabilisation pond system was topographically surveyed to de...
متن کاملOperation and recovery of a seasonally-loaded UK waste stabilisation pond system.
An intermittent discharge waste stabilisation pond system was trialled for treatment of a seasonal wastewater load from a campsite. The system showed rapid acclimatisation to incoming load, with chlorophyll-a exceeding 700 mg l(-1) within 2 weeks and filtered and unfiltered effluent biochemical oxygen demand below 20 and 30 mg l(-1) respectively. Good performance continued for some weeks, after...
متن کاملDynamic variation of supernatant quality in a dairy shed waste stabilisation pond system.
An intensive monitoring program of a standard two-stage dairy shed waste stabilisation pond system was undertaken to determine the incidence and extent of spatial and temporal variation of basic physio-chemical parameters, and to shed light on the longer term dynamic nature of in-pond conditions. The anaerobic-facultative pond system, located in a remote rural area, treats wastewater from the h...
