pH Adjustment Systems

pH Neutralization / pH Adjustment Systems for industrial wastewatertreatment 


Wastech-BioKill-System-Left Wastech-BioKill-System-Right

Biological waste, or "biowaste", produced by laboratories and the pharmaceutical and gene therapy industries is considered hazardous to human health and therefore requires inactivation before it can be safely discharged to the sewer. Common methods for performing this biowaste inactivation utilize either heat, which elevates and holds temperature to destroy any existing living microorganisms, or chemicals, which are injected and held at specific concentrations required to eliminate biological waste. Following inactivation, wastewater will typically need additional pH adjustment prior to final monitoring and discharge to the city sewer.

Wastech’s pre-packaged Biological Waste Inactivation Systems are available in multiple sizes and configurations, and compliment its line of skid mounted pH adjustment systems. Integrating these systems ultimately saves the client money and physical space by combining what are normally considered two separate and expensive systems. Since the combined, or "Composite" system is manufactured as a single unit there are no compatibility, interface, or communication issues commonly found in setups involving two separate systems. Cost savings can also be enjoyed through a reduction in field installation requirements and operator manpower.

The ProDELTA Thermal BioKill System is a skid-mounted thermal biowaste inactivation system that uses heat to elevate and hold a high temperature to "kill" living microorganisms, biological waste and cell waste. Cooling water is used to cool the waste stream prior to discharging from the skid. Instrumentation installed on the discharge piping monitors and records the effluent temperature, hold time, and flow of the waste being discharged. Optional validation features enable users to routinely verify system functionality.  If for any reason the wastewater does not meet dischargeable specifications the control system automatically recirculates it back to the holding tank for re-treatment.

Biological wastes are inactivated by injecting chemicals into a reaction tank in order to achieve the desired chemical concentration. The waste is held at the required concentration to achieve decontamination. Following decontamination the waste is neutralized to the required discharge pH before entering the sewer line.
