<p>A multi-chamber assembly for treating sewage in a small processing plant, has a primary clarifying chamber (18,20) and a main clarifying chamber (16) separated by a dividing wall (12). A pump (36) in the primary chamber passes soiled water into the main chamber with its lower end fitted with a catch bowl (40). An aerator (32) in the main clarifying chamber forms a water/air mixture under the bowl. <??>A multi-chamber assembly for treating sewage in a small processing plant, has a primary clarifying chamber (18,20) and a main clarifying chamber (16) separated by a dividing wall (12). A pump (36) in the primary chamber passes the soiled water into the main chamber through a channel over the dividing wall, with its lower end fitted with a catch bowl (40) open downwards. An aerator (32) in the main clarifying chamber forms a water/air mixture under the bowl. <??>The small multi-chamber sewage processing assembly has a control system which switches the aerator on for a given time span at a set time gap after the pump has been switched off.</p> |
