The LabDELTA® Batch is a skid-mounted pH adjustment system that is designed for neutralizing small-volume laboratory process wastewater. This batch system includes a 20 gallon holding tank that stores wastewater before being transferred to a 10 gallon reaction tank. Batch systems use one active treatment stage to ensure that the wastewater will be neutralized to the required discharge pH level before entering the sewer line.

LabDELTA® laboratory waste treatment units are quiet, sealed to eliminate vapors, and designed to be vented to building systems. Acid waste, and most lab liquid wastes are handled automatically. The units can be monitored locally with alarm lights, or remotely on a PC using Ethernet-based communications.
