Abstract
Песчаное фильтрующее устройство для обработки воды, включающее одинарный фильтрующий слой, или просто фильтр, который делает возможным получение отлично очищенной воды и имеет высокую эксплуатационную долговечность с высокими скоростями фильтрования. По преимущественному варианту соответствующее экспериментально полученное соотношение между высотой фильтрующего слоя, размером зерна примененного песка и скоростью фильтрации делает возможным определение размеров фильтрующего слоя с целью обеспечения оптимальных условий фильтрования. Дополнительно устройство, по данному изобретению, обеспечивает повышение эффективности обратной промывки фильтра, обеспечивающей восстановление эффективности фильтрации.
