This study investigated the sludge drying from a facultative pond in a dryer that employs two dehydration methods: thermal drying by infrared lamps and convective drying. For the tests, three thicknesses of sludge were ...

The Instituto Costarricense de Acueductos y Alcantarillados has a wastewater treatment plant for “Las Lomas” urbanization in Buenos Aires, Puntarenas. This plant is a single facultative pond which presents microalgae ...

The study of benthic metabolism is an interesting tool to understand the process that occurs in bottom water at wastewater stabilization ponds. Here, rates of benthic oxygen consumption and nutrient exchange across the ...

To investigate the characteristics and degradation process in sludge profile, three sampling sessions were made in three different places inside the primary facultative pond of Puerto Madryn city, which was located in a ...

Our knowledge on the algal community structure in waste stabilisation ponds is limited and it is unclear how physical-chemical changes affect the algal community structure and the treatment performance of waste stabilisation ...

Dissolved oxygen is an essential controlling factor in the performance of facultative and maturation ponds since both take many advantages of algal photosynthetic oxygenation. The rate of this photosynthesis strongly depends ...

Abstract Imitating natural lakes, pond treatment systems inherit a high complexity with interconnected web of biochemical reactions and complex hydraulic processes. As such, its simulation requires a large and integrated ...
