thickener to remove precipitate

Heavy Metals Removal Industrial Wastewater

The sludge from this process typically goes to a conventional thickener and filter press for dewatering prior to disposal. Dewatering produces an average 20:1 reduction in sludge volumes. The water from the dewatering system is returned for processing. Variations of this process can be used to precipitate

Two-stage precipitation process of iron and arsenic

01-12-2008  The target is to remove at least 90% of the iron in the first stage. The net production of precipitate is discharged from thickener No.1. The overflow from the first thickener is diverted to the first reactor of the secondary precipitation stage.

REMOVAL OF HARDNESS BY PRECIPITATION

for the removal of Ca. 2) Excess lime process i. The source water has high Ca and Mg hardness. ii. There is no non-carbonate hardness. In other words, alkalinity is enough for the removal of Ca and Mg hardness. iii. High Mg hardness requires excess lime to increase pH to 12-13 so that reaction kinetics is fast (super saturated solution).
