The effect of major operating parameters in spray drying sorber(=SDS) for automatic control for the simultaneous removal of acidic and organic gaseous pollutants from solid waste incinerator was performed. The field experiment was carried out in pilot scale test for the quantification of major operating parameters of hydrophilic and the hydrophobic pollutants. The removal efficiencies of SO2 and HCI in the 5wt% slurry condition were being increased with the increase of the stoichiometric ratio which is the molecular ratio of lime to the pollutant concentration, and with the decrease of inflow flue gas temperature in the pilot SDS reactor. The removal efficiency along the height of spray drying sorber was closely related to the temperature profile, and more than 90% of total removal efficiency was achieved in an absorption region. For the removal of acidic gas the optimum operating condition considering the economics and a stable operation is the 5wt% of slurry concentration, 1.2 of stoichiometric ratio and 250℃ of inflow flue gas temperature. For the organic gases of benzene and toluene the removal efficiencies were 20 - 60% which is much lower than that of acidic gas. The best removal efficiency was obtained at 1.5 of stoichiometric ratio and 250℃ of inflow flue gas temperature. The organic's removal efficiency along the height of spray drying sorber was quite different from that of acidic gas, that is, more than 60% of the total removal efficiency for benzene and 90% of the total removal for toluene were achieved in the dried adsorption region, which was formed at the lower or exit part of the reactor.

동일한 원수에 대하여 탁도제거 지배인자를 변화시켜가며 임펠러 형태별 탁도제거효율을 비교함으로써 관습적으로 설계 운영해오던 혼화과정의 문제점과 정수장의 최적 혼화저건을 만족시킬 수 있는 혼화기의 임펠러 타입 및 체류시간에 대한 운전기준을 제시하고자 하였다. 실험결과 혼화기의 종류는 탁도제거 효율을 물론 정수장의 경제적 운영을 위한 전력비 절감에도 효과가 있는 것으로 판명되었다. 또한 혼화지와 혼화기 설계기준에 일반적으로 활용되어 오던 속도구매 G이외에도
