Airflow rates measured with high-MERV filters installed in the upflow
and downflow system were 7% and 11% lower, respectively, than that with low-MERV filters installed.
(1987) ' and were extended to show that ' in contrast to the bubbly upflow
results ' void concentration near the pipe's centerline occurred for turbulent bubbly two-phase air/water downflow in a pipe.
Use of upflow
sludge blanket (USB) reactor concept for biological wastewater treatment.
Dunn included UV sterilizers and upflow
biofilters placed in the floor.
A year ago, in unpublished research, Angenent combined the "upflow
" system used in methane digesters with the MFC technology to eliminate the need for mechanical pumping and mixing.
Louis (WUSTL) recently reported that university researchers have developed a variant of a microbial fuel cell, dubbed an "upflow
microbial fuel cell," which they believe could eventually be used as a local power source.
STORMWATER TREATMENT AT CRITICAL SOURCE AREAS USING UPFLOW
The salts brought into soils of the Subdivision by capillary upflow
through irrigation, and rainfall during cropping season would be 122.85 and 202.30 thousand tons for both the scenarios, SCN1 and SCN2 respectively.
We conducted a laboratory scale feasibility study on the anaerobic treatment of spent pulping liquor effluent in upflow
anaerobic sludge bed reactors.
The leachate is also a function of the upflow
of groundwater or perched water in different parts of the landscape.
The paper examines the use of upflow
anaerobic sludge blanket (UASB) reactor in the treatment of high strength wastewater containing tetrachloroethylene or perchloroethylene (PCE).
