gravel filter in layer (UGFL) is a pretreatment process that is being used in tropical countries in multi-stage filtration systems (MSF) which combines dynamic roughing filters (DRF) in combination with different forms of pre-treatment filters (upflow
, down flow and horizontal flow gravel filters) and slow sand filtration (SSF).
Mendez-Romero, Lopez-Lopez, Vallejo-Rodriguez, and Leon-Becerril (2011) concluded that the peak of initial concentration, followed by exponential decay of the tracer concentration is a typical behavior of upflow
anaerobic fixed bed reactors used in the treatment of slaughterhouse effluents.
Quality of brackish aquaculture Sludge and its suitability for anaerobic digestion and methane production in an upflow
anaerobic Sludge blanket (UASB) reactor.
The treated domestic wastewater was pumped after passing through the Upflow
Anaerobic Sludge Blanket (UASB) system, installed at the Academic Unit of Agricultural Engineering of the UFCG, and stored in a tank with capacity for 500 L.
anaerobic sludge blanket (UASB) technology, normally referred to as UASB reactor, is a form of anaerobic digester that is used for wastewater treatment.
The aim of this study was to evaluate the performance of RAS in rainbow trout fingerling cultivation to remove N and biofilter solids in fixed support and upflow
in which different inoculum were used.

This is more obvious in vertical upflow
by reason of smaller density of ice particles whose buoyancy can further promote the slurry motion.
