Proper Sampling Points
As with all wastewater treatment plants, SBR samples are collected and analyzed for both process control and compliance reporting. Sampling locations must be carefully considered. SBRs that utilize influent-equalization basins have more representative flowpaced composite samples because the discharge is consistent in volume. In other words, flow equalization and true batch reactions allow for easier composite sampling because the same volume is entering and exiting the basin during each cycle.
Twenty-four-hour effluent composite samples should be flow-paced and include samples collected at the beginning and end of each decant event.
