The Horizontal flow is used for higher solids wastewater such as polishing wastewater from disc manufacturer. This Clarifier is a standalone system and is normally used for high flow rate application in range of 100 to 120 GPM.
The up-flow clarifier as a standalone system up to 1000 GPM can also be incorporated into the treatment system.
As a polishing step, Ion Exchange Technology is used to remove trace metals from the effluent of precipitation process. However, the selection of this ion exchange resin is quite important, as for such application the ion exchange system should be designed only to remove the specific metal in question. Therefore, rather than using generic Cation Ion Exchange resin, which will remove all Cations, a selective ion exchange should be employed to avoid frequent regeneration.
The effluent from the precipitation process is normally directed to a Neutralization or to what is normally referred to as AWN.
