Abstract
The present invention provides a concentration type aggregation reaction apparatus having a concentration screen, which enables an aggregation reaction to be conducted in sludge and the sludge to be concentrated by separation of a liquid by means of a single apparatus. The concentration screen is in a cylindrical form and includes slits having horizontal openings. A decelerating device is connected to an upper portion of a shaft for an agitator for agitation in the tank and brushes are connected to the decelerating device. The brushes are adapted to revolve along opposite surfaces (on a primary side and a secondary side) of the screen. By use of these brushes, aggregates adhered to the screen are continuously removed.
