Batch pH neutralization systems

Controlled batch-by-batch pH adjustment for intermittent effluent flows

ACTINI BNS systems deliver automated batch pH adjustment for liquid effluents from decontamination systems and other process wastewater sources. Engineered specifically for intermittent effluent flows, these systems ensure that facilities control discharge conditions safely and reliably.

What is a Batch pH neutralization system?

A Batch pH Neutralization System (BNS) is an automated effluent treatment equipment designed to treat wastewater in distinct, isolated volumes rather than through continuous flow. Non-neutralized liquid effluent is directed into a heavy-duty Polyethylene (PE) tank where dedicated acid and caustic chemical dosing pumps adjust the pH under active monitoring.

Once the precise target pH is achieved, the high-flow centrifugal pump discharges the safe, neutralized effluent through the outlet, providing complete control over discharge conditions.

Key applications for BNS equipment

The BNS series is engineered specifically to handle non-neutralized liquid waste streams across critical industrial and research environments, including:

  • Decontamination system effluents: Automated pH correction for biological wastewater discharged from liquid biowaste treatment units.

  • Intermittent industrial processes: Ideal for facilities with variable, non-continuous effluent release or batch-based production cycles.

  • High-temperature waste streams: Treatment of high-temperature discharges with the addition of an optional plate heat exchanger for liquid effluents exceeding 140°F (60°C).

Operational advantages of Batch neutralization

  • Absolute Discharge Safety: Effluent is retained in the neutralization tank until automated pH monitoring confirms the liquid meets exact discharge requirements.

  • Chemical Dosing Precision: Controlled addition of acid and caustic reagents prevents chemical over-dosing and optimizes chemical consumption.

  • Chemical Resistance: Heavy-duty Polyethylene (PE) tanks and dedicated chemical storage ensure long-term durability against aggressive acidic or alkaline waste streams.

  • Flexible Automation & Control: Fully automatic operation available with a dedicated electrical cabinet and HMI for real-time monitoring and seamless site integration.
