LabDELTA™ Extreme
Laboratory Waste Treatment
for Strong Acids & Caustics


Wastech's popular LabDELTA™ series of laboratory waste treatment systems has been augmented with a new compact package for extreme acid applications. When laboratory waste includes concentrated acid, strong acid or super acids with a pH between 0 and 2, this special design is required to manage heat and assure safety for technicians.

Wastech's new LabDELTA EXTREME™ design includes a collection tank and a transfer pump to safely and slowly inject the acid waste into the reaction chamber. Automated controls are provided by a PLC and special packaged software by Wastech. An integral discharge pump transfers the treated waste to the sink or sewer.

These are normally smaller, totally enclosed systems, and standard models are available for 2, 4 or 6 gallon batches. A waste fitting is accessed through the bolted cover. The discharge and water inlet lines are easily accessible. Installation does not require a contractor or electrician. Installation is easy with threaded fittings and 110V, single phase power provided by a 6-foot electrical power cord. The chemical supply, usually caustic soda (50% NaOH), is filled from the front without removing the cover. A remote control panel is available as an option.

This units will fit under the sink in existing lab cabinets or casework. For installations where an under-the-sink installation is not possible, Wastech now offers the new LabDELTA WASTE RECEIVER. This is a new countertop waste station that becomes a receiving station for acid waste, which it feeds directly to the treatment system using PVDF piping.

The Wastech LabDELTA EXTREME solution improves laboratory safety and makes automated laboratory waste treatment a reality even for the strongest acids.
