Method and apparatus for improving liquid flow

摘要

Especially for use in disinfecting water by bubbling in a gas such as ozone, novel apparatus having an inlet and an outlet for liquid and which defines a flow path therebetween, the path including, in succession, a downward flow zone and an upward flow zone, the zones being separated by a wall beneath which there is a gap for the flow between the zones, wherein the upward flow zone includes a perforate baffle, adjacent to the gap, such that there is substantially laminar flow throughout that zone.
