Abstract

A waste water treatment system consists of a mixing chamber in which chemicals, e.g. flocculants can be injected, and a tubular clarifier with a worm conveyor. The final stage takes place in a filter tank contng. a filtering medium. This saves much time and capital investment compared with a setting basin system. The clarification reaches a high enough standard to make the effluent fit for human consumption.
