Abstract
【解決手段】液体の処理のための装置は、少なくとも一つの内表面を有するチャンバーを有している。チャンバーは、少なくとも80パーセントが閉塞されている。装置はまた、紫外線(UV)透過性管を有しており、UV透過性管は、チャンバー内に配置され、それを通る液体の通路に適合されている。装置はUVランプをさらに有し、UVランプはUV透過性管内に配置されている。チャンバーと透過性管の間に反射性物質が散在されている。反射性物質は、UVランプによって発せられる光の少なくとも一部を反射するように適合されている。加えて、反射性物質は、少なくとも80パーセント反射性である。
Description
以下は、発明を実施するためにいま考慮されたベストモードを含む説明である。この説明は、限定する意味に取られるべきではなく、発明の一般的な原理を単に説明するために成されている。発明の要旨は、提出された請求の範囲を基準にして把握されるべきである。
I=I0e−αx
によって決定される。ここで、I0は初期強度、xは吸収媒体を通って伝わる距離、eは自然対数(e=2.718282)の底、αは媒体の特性によって決まる減衰定数である。媒体とその寸法が、光のかなりの小部分だけが媒体を通る単一経路の後に吸収されるようであるならば、図6〜8に示された効果が生じる。
