Formaldehyde and urea removal in a denitrifying granular sludge blanket reactor
(Elsevier, 2004-09)
Simultaneous formaldehyde biodegradation, urea hydrolysis and denitrification in anoxic batch assays and in a continuous laboratory anoxic reactor were investigated. In batch assays, the initial formaldehyde biodegradation ...
Fungal biocatalysts in the biofiltration of VOC-polluted air
(Elsevier, 2004-09-30)
Gas-phase biofilters used for the treatment of waste gases were originally packed with compost or other natural filter beds containing indigenous microorganisms. Over the past decade much effort has been made to develop ...
Formaldehyde biodegradation and its inhibitory effect on nitrification
(Wiley-Blackwell, 2004-05)
The simultaneous removal of formaldehyde and ammonium in aerobic cultures and the inhibitory effect of formaldehyde on ammonium oxidation were investigated. The influence of a co-substrate, methanol, on formaldehyde ...
Biofiltration of waste gases containing a mixture of formaldehyde and methanol
(Springer, 2004-04)
Several biofilters and biotrickling filters were used for the treatment of a mixture of formaldehyde and methanol; and their efficiencies were compared. Results obtained with three different inert filter bed materials (lava ...
Coliform concentration reduction and related performance evaluation of a down-flow anaerobic fixed bed reactor treating low-strength saline wastewater
(Elsevier Sciencie lted, 2004-09)
Low-strength saline wastewater may be generated by tourist facilities, industries and communities located in coastal areas. Sea salts, mostly chlorides, when present in wastewaters at high concentrations, can cause inhibition ...
Hydrodynamic behaviour and comparison of technologies for the removal of excess biomass in gas-phase biofilters
(Elsevier, 2004)
The hydrodynamic behaviour of a biofilter fed toluene and packed with an inert carrier was evaluated on start-up and after long-term operation, using both methane and styrene as tracers in Residence Time Distribution ...
