Batch Neutralization: Optimize Your Effluents with Actini Group

Actini Group designs batch neutralization systems that safely treat effluents on a per-batch basis. Each batch goes into a dedicated tank, where sensors and advanced automation precisely control the pH. This approach ensures complete chemical reactions, optimizes reagent use, and reduces human intervention while maintaining discharge compliance with environmental standards. Compact and modular, these units integrate easily into existing facilities.

Model: Batch Neutralization (BNS)
Capacity: 1,000 to 16,000 liters per day

Precision & Flexibility for Your Effluents

The ACTINI Batch Neutralization System (BNS) specifically targets pH adjustment for effluents coming from batch decontaminators, delivering precise and reliable treatment for each batch. Its modular design and multiple options allow the BNS to handle different types of wastewater, whether they come from industrial processes, washings, or occasional discharges. This flexibility makes integration into existing facilities easier while ensuring accurate pH control and full compliance with environmental standards.

Simplicity & Optimized Control

The BNS features an intuitive human-machine interface (HMI) that allows operators to easily monitor and adjust the neutralization process. Separate tanks for chemical solutions and the mixing pump provide optimal agitation and ensure sufficient contact time for a complete reaction. This setup delivers reliable neutralization while simplifying maintenance and reducing risks associated with human intervention.

Product highlights

Fonctions

Main functions : • Caustic and acid injection • Dilute, mix and adjust pH to correct value

Composition

• Polyethylene neutralization tank • Pumping skid with high-flow centrifugal pump

Automated effluent neutralization with precise pH control & safe discharge

Automatic injection of caustic soda and acid is used to neutralize the effluent pH.
The tank volume ensures a sufficient contact time (30 minutes) to complete the neutralization chemical reaction without any residual reaction after pH control.
pH adjustment in the tank is automatically managed by the pH probe located in the recirculation loop, which controls the acid and caustic injection pump.

The mixing pump ensures complete agitation of the tank volume with an hourly flow rate greater than five times the tank volume, allowing optimal dilution and mixing of the injected concentrated chemical solutions.
Once the effluent pH adjustment is completed, a high-flow pump empties the tank and measures the pH.
If the pH is within the correct range, the effluents are discharged. If the pH is outside the range, the effluent volume is returned to the neutralization tank for a second treatment.

Customizable Options: Total Performance & Flexibility

The BNS system can be equipped with a plate heat exchanger for effluents with temperatures above 60 °C.

A second neutralization tank can be added to ensure redundancy. An inlet allows direct connection to the client’s wastewater, while a dedicated electrical cabinet with a human-machine interface (HMI) facilitates control and supervision.

Separate tanks are also provided for the chemical solutions used in the process.
