Abstract |
The objective of this report is to develop an approach for comparing the health effects of land treatment and conventional treatment and discharge systems. An example assessment between activated sludge and slow rate land treatment of wastewater was presented based on the following assumptions: Flow of 3 Mgal/d of domestic wastewater. Activated sludge flowsheet with (1) disinfection and (2) surface water discharge. Slow rate land treatment flowsheet with (1) aerated lagoon preapplication treatment, (2) storage, (3) no disinfection, and, (4) percolate water recovery by underdrains and surface water discharge. The qualitative results indicate that both conventional and land treatment systems, which are well maintained and have good operating conditions, provide a large measure of safety for public health. Land treatment systems that involve slow infiltration offer greater protection against parasites and viruses, trace metals, nitrate, trace organics, and halogenated organics. |
