Study of coagulation/flocculation of water with moderate turbidity in sedimentation and floating by dissolved air
(Assoc Brasileira Engenharia Sanitaria Ambiental, 2020-07-01)
The processes of formation, growth, rupture, and rearrangement of flocs, which occur during coagulation/flocculation, significantly influence the removal efficiency of the aggregates in water treatment. Therefore, it is ...
The influence of floc size and hydraulic detention time on the performance of a dissolved air flotation (DAF) pilot unit in the light of a mathematical model
(Springer, 2014-12-01)
The influence of floc size and hydraulic detention time on the performance of a dissolved air flotation (DAF) pilot unit was investigated in the light of a known mathematical model. The following design and operational ...
Dissolved air flotation as potential new mechanism for intestinal parasite diagnosis in feces
(2021-12-01)
The parasitological examination of feces is recommended for the laboratory diagnosis of intestinal parasites due to its practicality, low-cost, and moderate diagnostic sensitivity. Dissolved Air Flotation (DAF) is an ...
Municipal waste-water treatment by lime ferrous sulfate and dissolved air flotation
(IWA PUBLISHING, 1995)
In this work a chemical treatment system for municipal wastewater using copper cementation effluent and lime as coagulants in combination with dissolved air flotation, was investigated. Copper cementation effluent (CCE) ...
Effect of dissolved oxygen concentration on red pigment and citrinin production by Monascus purpureus ATCC 36928
(Brazilian Society of Chemical Engineering, 2008)
The present study investigated the effects of agitation speed, N (200, 500, 600 or 700 rpm), and dissolved oxygen concentration, C (120, >70, 70, 60, 10 or < 10%), on red pigment and citrinin production by Monascus purpureus ...
