Apparatus for purifying water, comprising an upflow reactor with an influent distributing system to be connected to a central water supply system.

摘要

An apparatus comprising an upflow reactor (10) in which, while maintaining a sludge blanket, water to be purified can be contacted with one or more agents bringing the dissolved and/or dispersed material into a condition in which it can be separated from the water. …The influent distributing system includes a plurality of tube members assembled to form one or more strings (1-9). The strings have outlet openings obliquely directed downwards and through which the water to be purified can be introduced into the reactor space at a plurality of spaced locations. …For cleaning the ends of the strings they are provided with T-pieces closed by ball valves (14) disposed outside the reactor space and closed during operation.
