Method and plant for thickening sludge derived from water treatment by flocculation-decantation withballasted floc |
摘要 |
<p>A method is provided for thickening sludge produced through a ballasted flocculation process. The sludge and granular material from the ballasted flocculation process are directed to a sludge separator where the sludge is separated from the granular material. Thereafter the separated sludge is sent to a degassing area and the sludge is degassed. A flocculating agent is mixed or injected into the sludge. The sludge is directed to a sludge thickener with a load at a sill calculated on the surface of the thickener greater than 200 kgMIS/m<SUP>2</SUP>/day. This process produces a thickened sludge having a concentration greater than 10 gm/l.</p> |
