... inhibitor), 15 ppm diethylene triamine penta (methylene phosphonic acid) (DTPMPA) (scale inhibitor), 50 ppm THPS, and 150 ppm D-mix were injected into the vials at the same time to treat the biofilms in a new 7-day incubation period at 37oC. The test matrix is shown in Table 1. After the additional 7-day...
