EXPERIMENTAL FLOW The pilot plant, which consisted of an ozonation facUity, an ozone-resistant MF module, and a granular activated carbon (GAC) tower, had a capacity of treating about 35 m /day of water. The experimental flow, as shown in Figure 5.8, had two trains in which ozone was injected before the MF module using an ejector (process A) and a diffuser (process B). The raw water taken from the Edo River through a raw water receiving tank was treated by an automatic strainer with a mesh size of 100 p,m. Equipment specifications of treatment units are shown in Table 5.4.
