К физическим методам очистки воды относят:

процеживание;
отстаивание;
фильтрование (в том числе центробежное) - Очистка воды;
ультрафиолетовая обработка.

Процеживание представляет собой пропускание очищаемой воды через различные решетки и сита, на которых происходит задержание крупных загрязнителей. Этот метод относится к грубой очистке и часто выступает в качестве предварительной стадии. Его назначение – удалить из очищаемой воды легко отделяемые загрязнители для снижения нагрузки на очистные сооружения и обеспечить работоспособность последующих установок тонкой очистки, которые могут выйти из строя из-за попадания крупных механических включений.  




Выделяют ряд способов очистки, принципиально отличающихся по типу химического взаимодействия:

нейтрализация;
окисление;
восстановление.

Окисление и восстановление также используется для очистки воды от различных загрязняющих веществ, хотя на практике соотношение их использования сильно смещено в сторону окислителей. Несмотря на то, что в реакции нейтрализации также протекают параллельные процессы окисления и восстановления, данный метод отличается использованием значительно более сильных окислителей и восстановителей, так как целевые загрязнители просто не будут вступать в реакцию с веществами, используемыми в методе очистке нейтрализацией. С их помощью проводят обезвреживание различных токсичных веществ, и также веществ, трудно извлекаемых из воды иными способами. Осуществлением реакций окисления добиваются переведения токсичных загрязнителей в менее токсичные или нетоксичные формы. Также за счет использования сильных окислителей достигается гибель микроорганизмов, наступающая вследствие окисления их клеточных структур. В основном применяют хлорсодержащие окислители: газообразный хлор (CL2) а также различные хлор соединения, такие как диоксид хлора (CLO2), гипохлориды калия, натрия и кальция (KCLO; NaCLO; Ca(CLO)2). Помимо этого использую перекись водорода (H2O2), перманганат калия (KMnO4), озон (O3), кислород воздуха (O2), дихромат калия (K2Cr2O7) и т.д.
