浮選砂-
The effects of potassium permanganate, chorine and ozone were compared and the results showed that although all of them could enhance coagulation and then reduce the turbidity of the water after subsequent treatment units, potassium permanganate and ozone were more effective to ensure the quality of the water after air - flotation and sand - filtration
對高錳酸鉀、氯和臭氧三種氧化劑進行分析比較，結果表明三種氧化劑均能提高混凝效果，但高錳酸鉀預氧化和預臭氧化在提高氣浮和過濾出水水質保障率方面均優于預氯化。 -
Suspended solids including fine particles and colloids cannot be removed efficiently with gravitation sedimentation ; they are removed using centrifuge, dissolved air flotation, diatomaceous earth filtration, coagulation sedimentation plus rapid sand filtration while dissolved solids are removed with ion exchange, ultrafiltration, activated carbon adsorption and chemical oxidation
懸浮固體之去除包括微顆粒及膠體物，無法以重力沉澱之物質，可採用離心分離機、空氣浮除法、矽藻土過濾法、混凝沉澱加快濾池等去除之。而溶解性固體去除則採用離子交換法、微細孔濾膜過濾、活性碳吸附以及化學氧化等去除之。
