1. 氧化劑置入後約 1.5 分鐘，顆粒粒徑將成長至最大值，倘若持續以相同 攪拌強度進行攪拌則粒徑將開始破碎。
2. 顆粒粒徑與施予之攪拌強度及鐵錳濃度比值有關，當攪拌強度越弱則顆
粒粒徑越大，反之則粒徑越小；鐵錳濃度比值越大，粒徑越大。然而影 響粒徑之關鍵在於攪拌強度。
3. 攪拌強度越弱則碎形維度值越小、顆粒結構較為鬆散、濾餅比阻抗較
大，過膜通量較小；反之則碎形維度值越大、顆粒結構較為緊實、濾餅 比阻抗越小，過膜通量較大。
4. 薄膜濁度去除率與攪拌強度成反比關係。當攪拌強度較弱時，顆粒粒徑
較大且結構較鬆散，較容易被壓縮，使得顆粒不容易受擠壓而貫穿薄 膜；反之則易因擠壓而貫穿薄膜，導致濁度去除率較低。
5. 水體中鐵錳濃度比值較高者所生成之鐵、錳氧化物較為疏水，當其吸附 於薄膜孔洞內，會使薄膜較為疏水，增加薄膜內孔洞阻塞之阻抗；當其 累積於薄膜表面形成濾餅時，將使得濾餅阻抗增加，降低薄膜之過濾效 能。
5.2 建議
本研究所探討之顆粒特性包含顆粒粒徑、碎形維度及界達電位，雖然 證明鐵錳氧化物顆粒聚集是在電中性條件下藉由碰撞及吸附作用所形成，
由於並無探討所形成顆粒之顆粒強度所以無法直接證明顆粒於過濾過程中 會因擠壓而產生形變，故後續可針對前氧化攪拌強度對於顆粒之強度作更 深入之探討。此外，本研究所選用之過膜壓力太高，導致過濾後薄膜之濁 度去除率較低，故可探討過膜壓力對於薄膜過濾後濁度去除率之差異。
