DownloadButtonThe LabDELTA® Concentrated pH adjustment system is a skid-mounted system designed for neutralizing smallvolumes of concentrated laboratory wastewater. This system includes holding tanks for storing both acidic and caustic wastewater. The wastes are alternately added in small increments to a reaction tank containing a heel of water. Once level is made in the reaction tank and the wastewater is neutralized it is discharged to the sewer. If a waste is depleted during a treatment cycle, the system automatically switches to using chemical reagents for pH neutralization.
