Title
The Characteristics of The BAC process using the down Stream of Nak-Dong river Water
강용태Yong Tae Kang
Abstract
Recently, the down stream of the Nak-Dong river, which is Pusan`s main water source, has been rapidly contaminated by the inflow of inadequately treated domestic sewage and by the industrial waste water from middle and upper reaches of the river. The main pollutants are composed of NH₄-N, ABS, color, THM precusors, UV absorbent materials, KMnO₄ consumption, iron, manganese and so on. The government is spending money building more BAC beds without improving the facilities of the pre treatment and conventional system in order to remove these pollutants. This can cause the BAC bed to be over loaded, which may shorten it`s life. The system itself may turn out to be in effective in removing the contaminants. Therefore, we need further research on the pre and conventional rapid filtration facilities.
