... Optimal pH, and ORP (oxidation-reduction potential) are required for the correct operation of the biological process. This is achieved through the controlled injection of process air (depending on the raw water ORP), which increases the ORP. For some applications, a pH adjustment is necessary to obt ...

... rate and bacteria transport. Filters were manufactured by combining clay-rich soil with water, grog (previously fired clay), and flour, pressing them into cylinders, and firing them at 900 °C for 8 h. The pore-size distribution of the resulting ceramic filters was quantified by mercury porosimetry. ...

... Upflow submerged filters have the water flow from bottom to top, while downflow submerged filters have the water flow from the top toward the bottom. The oxygen supply for the bacteria in a submerged filter must be supplied from the water, a factor that often sets the flow rate through the filter at ...
