Cavitation - Purifying Water with Ultrasound | Tomorrow Today
Antibiotics, psychoactive drugs, hormones and many other substances enter the water cycle and the food chain without people being aware of it. Sewage treatment plants do not completely break down these biologically active substances. Now scientists have developed a way to purify water without resorting to chemicals. Ultrasound and high pressure combine to create thousands of tiny cavities in the water. They decay spontaneously, generating enough energy to break down the impurities. This method, known as cavitation, has been demonstrated successfully in the laboratory. Soon it is to be tested on a large scale.
氣蝕 - 超聲今日|明日淨水
抗生素，精神藥物，激素和其他許多物質進入水的循環和食物鏈，沒有人意識到這一點。污水處理廠不完全分解這些生物活性物質。現在，科學家已經開發出一種方法來淨化水，而不訴諸化學品。超聲和高壓水相結合，創造數以千計的微小腔。他們自發地衰變，產生足夠的能量來打破的雜質。 ，作為蝕已知，這種方法已被證明成功地在實驗室裡。很快，這是進行大規模測試
