Abstract

Багатоступінчаста аераційна установка включає в себе щонайменше два вертикально орієнтовані аераційні блоки. Кожний аераційний блок утворює вертикально видовжену камеру аерації, яка містить верхній впуск і нижній випуск. Нижній випуск кожного зі згаданих аераційних блоків подає потік текучого середовища, який містить рідину, і газ, у верхній впуск, розташований нижче одного із згаданих аераційних блоків. Кожний аераційний блок містить аераційну головку, з'єднану зі згаданим верхнім впуском так, що потік текучого середовища, який проходить через верхній впуск в камеру аерації, повинен пройти через згадану аераційну головку, причому згадана аераційна головка аерує рідину з газом в потоці текучого середовища.
