The collection efficiency was found to decrease with increasing temperature; the total collection efficiency decreases strongly when the solid velocity increases.
32.
In Sana'a, the collection efficiency of water and sewer bills increased from 60 % to 97 % during the same period.
33.
In an ESP, where particle charging and discharging are key functions, resistivity is an important factor that significantly affects collection efficiency.
34.
However, these spray nozzles may use more power to form droplets than would a venturi operating at the same collection efficiency.
35.
The collection efficiency was found to decrease with increasing temperature; the total collection efficiency decreases strongly when the solid velocity increases.
36.
The instrument did not find much attention in the scientific community at the time due to the lack of light collection efficiency.
37.
In 2013-14 most Kenyan WSPs recorded good revenue collection efficiencies with an average of 93 %, up from 86 % in 2006-07.
38.
Higher collection efficiencies can be achieved by increasing the flue gas humidity ( i . e ., cooling using water spray ).
39.
At that time water revenues were extremely low, there was no functioning customer database, virtually no metering, and low bill collection efficiency.
40.
Fabric collectors are frequently used in minerals processing operations because they provide high collection efficiency and uninterrupted exhaust airflow between cleaning cycles.
