How to treat the sludge of air flotation machine

The dissolved air floater will produce scum and sludge during its operation. The scum will be hung into the scum tank by the scraper, and then flows into the sludge tank by the scum tank. The sludge produced by the air floater is generally in the sedimentation area or the reaction area. The sludge openings in these two areas are at the bottom of the equipment, and are generally discharged into the sludge tank for storage by the pressure of water.

The sludge in the sludge tank of the air flotation machine is pumped into the screw stacker or plate and frame filter press by screw pump for sludge drying. The dried sludge can be transported outside or used for greening and fertilization.

We can connect the filter press with the pipe inside, and then operate it inside, so that we can treat the internal sludge, but we must ensure their proportion in the process of treatment, to ensure that its solid content of sludge is about 2%, and then we add the polyacrylamide in the equipment, which is more thorough and less costly, The sludge inside the air flotation machine can be completely treated.
