pH Adjustment Systems

pH Neutralization / pH Adjustment Systems for industrial wastewater treatment 

Solves Laboratory Waste Treatment Problems


LabDELTA™ from Wastech automates laboratory liquid processes

from waste treatment to dispensing and chemical mixing.

LabDELTA™ from Wastech Controls solves laboratory waste treatment problems with small-volume, automated systems. These are ideal as school laboratory waste treatment systems. Complete packages are available in either 2, 4 or 6 gallon batch designs or 1, 2 or 3 gpm continuous designs with complete controls, including communication options for alarm reporting. Acid waste neutralization (AWN) including strong acid neutralization (0-2 pH) is typical. Other systems handle heavy metals, fluoride reduction, and pH adjustment for caustic fluids, automatically and without risk to lab personnel. Accidents from exothermic reactions, spills, burns and glass breakage are eliminated.

Using various system designs including two-stage neutralization, limestone pretreatment, or packaged chillers with PVDF or Telfon heat exchangers, Wastech Controls treats the waste safely and prepares it for dumping into the sewer. The units are small and compact, fabricated of polypropylene, with drip pans or double-containment as requested, and include all sensors and controllers.

Wastech Controls has been supplying waste treatment solutions since 1987, and brings this design experience into the lab with reliable designs and durable components such as pH sensors and pH controllers.

Wastech's LabDELTA™ laboratory waste treatment units are quiet, sealed to eliminate vapors, and designed to be vented to building systems. Solvent waste, acid waste, and most lab liquid wastes are handled automatically. Pump options incorporating high level alarms and automatic shut-offs are available to transfer untreatable waste to drums. The units can be monitored locally with alarm lights, or remotely on a PC using web-based TCP/IP communications or modem-to-modem dial-up.

LabDELTA units are small enough to be located in the laboratory itself. They can include collection tanks with pumps or be located near floor drains for gravity discharge into the sewer. The units can be located under counters or in cabinets. Control panels are normally located on the units, but can be remotely mounted anywhere in the lab.
