An acid neutralization system treats acidic or alkaline wastewater, adjusting its pH to a safe range before the water is discharged to drain. The system monitors the pH of the incoming stream, doses a neutralizing reagent to bring it within the required limits, and releases the water only once it meets discharge requirements. This keeps a facility compliant with wastewater regulations and protects drains and municipal systems from corrosive discharge.
Systems that provide pH neutralization operate as either continuous-flow or batch neutralizers. A continuous flow system treats wastewater as it arrives, while a batch system collects and treats a fixed volume at a time. The right choice depends on the facility’s flow rate and how steady that flow is.
Modutek builds acid neutralization systems for industrial and semiconductor facilities, sized from 5 to 500 gpm. Every system is self-contained, can be installed indoors or outdoors, and is designed, assembled, and tested in-house in San Jose, California.
Modutek offers a full range of chemical handling equipment and systems and can customize products to meet your specific manufacturing requirements. modutek Corporation designs and manufactures a complete line of self-contained Acid Neutralization System products that are compact, easy to install and inexpensive to operate. Continuous flow or batch acid neutralizers are available. These unique designs can be modified to fit the specific dimensional requirements of virtually any operation environment. The Acid Neutralization System throughput capacity can also be tailored to meet the needs of industrial production facilities of all sizes.





Sized from 5 to 500 gpm. Compact design with double containment and an on-board reagent tank option.
The system can be installed indoors or outdoors for ease of plumbing connection and electrical hookup.
The pH neutailization system treats acidic or alkaline wastewater streams in fully automatic operation, with no operator intervention required for routine treatment.
Two-stage systems handle normal applications. Three-stage systems are used for the most demanding plant conditions, where a single neutralization pass is not enough to reach the required pH.
Systems from 5 to 100 gpm use unitized construction with half-inch-thick thermo-welded polypropylene. Larger systems are designed with skid-mounted construction in polyethylene, fiberglass, or lined steel.
Microprocessor pH control provides high accuracy, ease of calibration, and reliable operation. A digital chart recorder continuously monitors and records the pH levels of the discharge, so the facility has a record that acid waste neutralization requirements are met.
The system includes high- and low-pH neutralization monitoring in the final chamber, a liquid sensor in the double containment, low-level reagent storage tank alarms, and remote alarms that can be tied to relays in the control panel.

It adjusts the pH of acidic or alkaline wastewater to a safe, neutral range before that water is discharged. The system acts as a neutralizing reagent and releases water only once it is within the facility’s limits, ensuring wastewater discharge remains compliant with regulations.
A continuous-flow pH neutralization system treats wastewater as it arrives and is suited to facilities with steady, ongoing flow. A batch system collects a fixed volume, treats it, then discharges it, which suits lower or less predictable flow. The choice depends on a facility’s flow rate and its consistency.
A two-stage system handles normal wastewater applications. A three-stage system is used for the most demanding plant conditions, where the incoming stream cannot be brought within pH limits in a single neutralization pass and needs an additional treatment stage.
A digital chart recorder continuously monitors and records the pH of the discharge. This provides the facility with an ongoing record showing that treated water met neutralization requirements before release.
Yes. The system is self-contained and can be installed indoors or outdoors. Indoor installation is preferred in colder climates. Outdoor installation makes plumbing connections and electrical hookups easier, and placement is confirmed during the design stage.
