Enhanced coagulation or enhanced softening or GAC10*, with chlorine as the primary and residual disinfectant.Control of treatment processes to reduce disinfectant demand and control of disinfection treatment processes to reduce disinfectant levels.Control of ozone treatment process to reduce production of bromate.* GAC10 means granular activated carbon with an empty bed contact time of 10 minutes and reactivation frequency for GAC of no more than six months.
The development hereby permitted shall not be carried out otherwise than in accordance with the following approved plans: GA_C_BL, GA_C_00 Rev C, GA_C_01, GA_C_02, GA_C_03, GA_C_04, GA_C_05, GA_C_06, GA_C_07, GA_C_08, GA_C_09, GA_C_10, GA_C_11, GA_C_12, GA_C_RL, EL_NW Rev A, EL_SW Rev B, EL_SE Rev B, EL_NE Rev B, EL_NW_SE Rev B, S_AA Rev A, S_BB Rev A, D_01, D_02, D_03, D_04, D_05, EL_ST Rev A.
SWAT executes the “GAC10” step as follows:• All chlorine and ammonia doses contributing to CT are removed.• Any existing GAC unit processes are removed.• SWAT sets the reactivation interval at 360 days for the GAC10 system to be added.
The “GAC20 + Raw Water Ozone” step applies to all plants with initial technology level less than or equal to “GAC20 + Raw Water Ozone,” except for:• Softening plants• Small systemsThis step is implemented in the same manner as the “GAC10 + Raw Water Ozone” step, except a GAC20 system is added instead of a GAC10 system.
