Effluent treatment system for the pharmaceutical industry BNS series

for laboratoriesmodular

The ACTINI Batch Neutralization System (BNS) has been specially designed to adjust the pH of effluent from batch decontaminators. Featuring a wide range of options, the system is modular and can perfectly handle wastewater from other sources. 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 Neutralization Automatic injection of caustic and acid to neutralize effluent pH The volume of the tank allows sufficient contact time (30 minutes) to generate the chemical neutralization reaction without any residual reaction after pH control. pH adjustment in the tank is managed automatically by the pH probe located in the recirculation loop, which controls the acid and caustic injection pump. The mixing pump stirs the tank volume with an hourly flow rate more than 5 times its volume, ensuring optimum dilution and mixing of the concentrated chemical solutions injected. Once the pH of the effluent has been adjusted, a high-flow pump empties the tank and measures the pH. If the pH is within the correct range, the effluent is discharged. If the pH is out of range, the effluent volume is returned to the neutralization tank for further treatment. Options Plate heat exchanger for effluents above 60°C Neutralization tank redundancy (2nd tank) Inlet for connection to customer’s wastewater Dedicated electrical cabinet with HMI Dedicated chemical solution tanks
