    Abstract: 本研究於板新淨水場設過濾模型廠,以新型濾料種類、濾料厚度與濾速為操作變數,檢討其對新型濾料過濾去除濁度及粒徑分佈之影響,並評估新型濾料過謹、取代化學沈澱池或過濾池之可行性。研究結果顯示中空圓筒型濾料去除濁度之效果優於其他兩種浮體濾料,當膠凝水為過濾、進流水,濁度範圍10-60 NTU,濾速於50-75 m/ 日以下且濾料厚度180 cm之條件,濾程48小時內過濾出流水濁度平均值低於3NTU,顯示中空圓筒型濾料過濾可作為預濾,取代傳統化學混提沈澱池。相對地,沈澱水濁度l.45-11.8NTU時為過濾進流水,濾料厚度180cm且濾速大於100m/日時,由於過濾能力較傳統雙層港料(石英砂與無煙煤)不佳,故中宣圓筒型濾料過濾、不過取代傳統過。此外,過濾水之粒徑分佈顯示粒徑2-5μm以下之顆粒數佔總顆粒數約80%以上,當濁度大於0.5 NTU時,總顆粒數與濁度具良好相關性(R2 =0. 98) ;但濁度低於0.5NTU時則相關性較差。
