Actini Group neutralization systems automatically adjust the pH of industrial effluents before discharge or further treatment. Designed for the pharmaceutical and biotechnology industries, research laboratories, production facilities and decontamination installations, our solutions provide reliable neutralization of acidic or alkaline wastewater while meeting the most stringent environmental and regulatory requirements.
Our systems are available in both batch and continuous configurations to suit every process, flow rate and plant layout.
Effluent neutralization is a physicochemical process used to automatically adjust the pH of industrial wastewater, making it suitable for discharge or downstream treatment processes.
Wastewater generated from production, cleaning, decontamination and laboratory activities may be acidic or alkaline. Uncontrolled pH levels can create risks for the environment, sewer networks, wastewater treatment facilities and industrial equipment.
To ensure compliant discharge, neutralization systems continuously monitor pH and automatically inject the required reagents to reach the target range. This regulation ensures reliable, safe and repeatable neutralization while minimizing operator intervention.
Today, neutralization is widely used in pharmaceutical manufacturing, biotechnology facilities, research laboratories, chemical industries and biological effluent decontamination installations.
pH (potential of hydrogen) is a measurement used to determine the acidity or alkalinity of a liquid on a scale generally ranging from 0 to 14.
In industrial wastewater treatment, pH control is essential to ensure compatibility with collection networks, treatment facilities and environmental discharge requirements.
Insufficiently neutralized effluents may cause:
Industrial wastewater can exhibit pH values that are incompatible with discharge requirements.
Without proper treatment, these effluents may:
Neutralization helps to:
Neutralization is used in a wide range of applications.
Wastewater containing acids, alkalis or chemicals generated by industrial processes.
Wash water, cleaning solutions, production discharges and wastewater generated from GMP manufacturing processes.
Effluents generated from fermentation, cell culture and bioproduction activities.
Wastewater generated during Clean-In-Place (CIP) operations.
Wastewater generated by research laboratories, R&D facilities and contained environments.
Following biological or thermal treatment, effluents may require an additional neutralization step before discharge.
The principle is based on the controlled addition of chemical reagents to automatically adjust pH.
The process generally includes:
Thanks to automation, the system continuously adjusts reagent dosing to maintain the desired pH range
An industrial neutralization system generally consists of several pieces of equipment working together to ensure reliable pH adjustment:
The exact configuration depends on the type of effluent, flow rate and site requirements.
Several factors influence neutralization performance:
Proper system sizing must take all these parameters into account to ensure reliable operation and long-term compliance.
The choice mainly depends on the volume of wastewater to be treated and the operating mode of the facility.

An effluent neutralization system automatically adjusts wastewater pH before discharge to ensure environmental compliance.
Neutralization acts on pH, while decontamination aims to eliminate or inactivate biological agents or contaminants present in the effluent.
When effluents are generated in batches or intermittently.
Acceptable pH values depend on local regulations and the discharge destination. In many cases, wastewater must be neutralized before being discharged to a sewer network or treatment facility.
An acidic effluent has a pH below 7, while an alkaline effluent has a pH above 7. Both may require adjustment before discharge when outside authorized limits.
Yes. Systems can integrate various options depending on process constraints, treatment volumes, effluent temperature and operational requirements.
When effluents are generated continuously and require permanent pH control.
Chemical, pharmaceutical and biotechnological effluents, wash water, CIP discharges and wastewater from decontamination systems.
To protect networks, equipment and the environment while complying with applicable regulations.
Neutralization systems are used in pharmaceutical, biotechnology, chemical and food industries, as well as research laboratories and decontamination facilities.
An automatic system continuously measures pH and automatically adjusts reagent dosing. This improves treatment accuracy and reduces the risk of human error.
Depending on the wastewater characteristics, neutralization generally relies on the controlled injection of acid or caustic soda to bring pH back within the target range.
