Title: Flocculation reactor with fixed bridge - with rotating internal structure for pptn treatment of industrial wastes
Inventor: HOEKE BERT ING GRAD
IPC: B01D21/00
Filed: 1975-11-19
Abstract: Flocculaton reaction is in the form of a circular concrete or sheet steel tank, it is surmounted by a fixed bridge to which the internal structure is secured, so that it can rotate. This structure consists of an external cylinder and an internal cylinder and is suspended from the bridge by an annular bearing, supporting arms for hte sludge evacuation blades are mounted on the lower edge of the cylinder. Under the action of the rotating pump impeller, the raw water entering through the pipe is brought into circulation in the directions shown by the arrows. This brings it into contact with a layer of sludge, already present and it also receives chemical prods. fed from the bridge. The microfloccules initially present are turned into macro-floccules, these, because of their wt. descend through the ring and are deposited on the lower part of the decantation chamber. They are transported into the cone by the blades, which rotate with the rest of the internal structure, adn are pumped to a dehydrating plant. The clarified water, free from floccules, flows out through the channel to the evacuation pipe for the treated water. The reactor is simple and clarification is attached without turbulence. It forms the final stage in pptn. plants for treating industrial waste water. The rotation of the internal structures under a fixed bridge is simpler, from the constructional point of view, than the use of a rotating bridge.
