Preliminary study on pollutant discharge from domestic wastewater and pollutant load in the river: a comparative study between Japan, Thailand and Bangladesh (original) (raw)

Flooding control and water pollution abatement have been major problems in the surface water in the Asian countries including Thailand and Bangladesh. We have conducted field surveys and secondary data collection to clarify the relationships between domestic wastewater discharge and pollutant load in the river from October to December in 2006. This paper reports summary data which will be a part of basic data sets for the estimation of pollutant discharge per capita (PDC) and pollutant load per capita flowing into the water body (PLCwb). For the estimation of the pollutant load in the river, river flow fluctuation derived from the tidal level fluctuation was important to be considered in regards to both water quantity and quality, because the river bed in these areas are rather flat.
