Acid Neutralization Features
that Add Value

Lower operating costs and automation are what process engineers and operators are looking for in an acid neutralization or caustic neutralization system. As engineering departments are reduced in size, the system must operate automatically with alarms communicated by email or cell phone. Performance must be reliable at all times, even in the presence of acid and caustic surges.

You will not find another waste neutralization system with better components or as many high-end features offered as standard as Wastech's OMEGA™ waste neutralization systems.

Double-contained chemical supply tanks are always provided by Wastech for safety and reliability. The tanks are normally custom fabricated of PP sheet, but can be modified with a carbon steel outer tank for NFPA non-flammable separation of dissimilar chemicals. Industrial, oversized, metering pumps allow systems to react rapidly to waste stream surges with slugs of strong acid or chemical dumps that would upset conventional designs and cause NOVs.

Seismic Zone 4 compliance is no problem for Wastech. As a California supplier, we understand seismic requirements and routinely deliver seismic designs and PE-stamped drawings. Seismic documentation does not delay our projects and can be presented with the submittal package. States other than California are increasingly requiring seismic compliance.

Quality control panels. As a CSIA Certified Control System Integrator, Wastech builds UL-labeled panels with CAD wiring diagrams, labeled and color coded wiring, and quality components. Our control panel workmanship is unequaled in the industry. Advanced software control. As an expert in neutralization, Wastech has developed a unique software program named Zeus™ for automated and predictable control of acid neutralization systems. Zeus™ includes pH probe and alarm management, and can handle multiple-stage operation. Nothing like it exists elsewhere on the market.

Platforms with tie-downs and welded system components maintain system integrity during mechanical stress, such as earthquakes. Special piping connections, such as flanged inlets and outlets, can be requested. Forklift access is standard.

Splash-guard double tubing over all fittings and supply lines provides operator safety in the event of a leak. Most other neutralization suppliers use unprotected tubing from the chemical metering pumps to the tanks, so that acid and caustic under pressure are continual operator risks.

Heavy-duty mixers, such as Lightnin, are the key to fast reactions and reliable neutralization operation. Wastech takes mixing very seriously, and mixer performance is monitored by software. Each mixer is specified for the tank shape and size for the application. Tank baffles may be included. Wastech refuses to user low-cost mixers or metering pumps.

Tank sizes and shapes are designed to assure that the discharge is within limits for all expected surges in the waste stream. Large tanks are reinforced with galvanized bolted uni-strut enclosed in PP channels to insure tank shape stability and long life without rusting. (This compares to the welded uncoated carbon steel angle iron used by most fabricators.)

Wastech uses only the most reliable industrial sensors, calibrates them, installs them correctly, and then monitors their life cycle with software. Since pH sensors can be the weakest links in the control system and can be consumed by the waste stream itself, some Wastech systems use three pH probes in each tank for redundancy. Quality components and fail-safe design result in operational savings and lower maintenance costs. When the system is automated, works reliably, and anticipate problems, the system discharge is always within limits and NOVs (notices of violation) are eliminated!
