Liquid Chlorination

Liquid_chlorinatorLiquid chlorinators typically use liquid chlorine bleach that is dosed into the wastewater prior to distribution.

These systems generally use an aspirator to draw chlorine from a reservoir. The chlorine is discharged into the pump tank to react with the wastewater. The aspirator requires that the pump be operating to develop the vacuum to draw a chlorine dose into the pump tank.

Factors affecting the performance of liquid chlorine disinfection include: mixing, contact time, dosage, and chlorine residual control. With proper system calibration, monitoring, and operation and maintenance, liquid chlorination can be a very effective means of disinfection for onsite wastewater treatment systems.
