Abstract
Description
この特許出願は、2019年5月21日に出願された米国特許出願62/851,002の利益を主張しており、当該内容は、この出願に引用されている他のすべての参考文献とともに参照により組み込まれている。
ステージ108では、砂、藻類、またはその他のろ過材で構成される第2ステージのフィルターを使用して、バクテリアなどの小さな汚染物質を除去する。
1.汚染された水は最初に活性炭フィルターに入る。
2.微生物を殺すのに使用される周波数は、約254ナノメートルの波長である。
水の前処理のいくつかの前提条件は、1ネフェロメ濁度単位(nephelometric turbidity unit: NTU)未満の濁度まはたヘイズ(haze)、1リットルあたり約10ミリグラム未満の浮遊物質、色なし、1リットルあたり約0.3ミリグラム未満の全鉄、1リットルあたり約0.05ミリグラム未満のマンガン、ガロンあたり約7グレイン(grain)未満の硬度を含む。石英ガラススリーブは、華氏約104度の温度を維持するように設計されている。
1.インドでは、人口の6%しかきれいな水を利用できず、7,580万人が安全な飲料水を利用できない。
1.約14体積パーセントの酸化銅粉末と約2.5重量パーセントのポリビニルアルコール(polyvinyl alcohol: PVA)結合剤からなる銅粉末スラリーは、約30ミリリットルの脱イオン水と混合することによって作り出した。
3.次に、冷却した銅棒の上に置いたシリコーン型にスラリーを注いだ。銅棒の上部の温度は、液体窒素を使用して摂氏約-30度に固定し、コントローラーを使用してその温度に維持した。
接続1116は、上述の接続1105と同様であり、水フィルターから発泡金属フィルター材料に水を移動させる物理的接続または技術であり得る。発泡金属フィルターは、水ろ過の第2段階である。
