In order to purge the floc blanket to keep the desired concentration of flocs in it we are designing a Floc Hopper whose objective is to trap floc and concentrate them so that when we purge, not much water is wasted. The postitioning of the floc hopper to accomplish this is yet to be determined.

Sludge Drain

The main innovation on the sludge drain is its cover. Initially the cover served also as a support for the slope, but now, as the slopes are built by a solid piece of concrete, this is not necesary any more.
One of the advantages of the new design is that it is much easier to clean, as the only removable parts will be the 6 inch PVC inlet manifold and the drain cover which was designed in sections to make it easy to remove. Also, the fact that the flocs will settle inside the sedimentation tank, which has a sludge drain specifically designed to purge all the sludge, will imply that after emptying the tanks the remaining sludge in the bottom of the sedimentation tank will be very little to none.
The idea of designing the sludge drain cover with small orifices is to create an even vacum along the entire length of the sedimentation tank to reduce dead spaces where sludge could be accumulated.
