Hospital effluent treatment system

for sterilizersfor autoclavesfor laboratory

Overview
High-temperature effluent treatment is essential in hospitals, laboratories and sterilization units. These medical or industrial wastewaters are often too hot for direct discharge and must be cooled to meet regulations and to protect sewer networks and equipment. The solution relies on buffer tanks and cooling systems that progressively lower temperature, enabling compliant and continuous effluent management.

Applications
Sterilization services, cart washers, hospital laundries, autoclaves and similar equipment

Principles and operation

• One or several buffer tank(s): effluents are collected and stored with continuous temperature monitoring.
• Gradual cooling: water is cooled by mixing with cold water or via dedicated heat exchangers.
• Safe discharge: when temperature and pH meet regulatory thresholds, effluents are discharged to the sewer.

Technical features and design options

• Volumes sized according to flow rates, up to 10,000 liters.
• On-line treatment with multiple custom tanks.
• Tank materials selected for high-temperature resistance.
• Custom manufacturing to fit site constraints (doors, corridors, access).
• Temperature monitoring and alarm system.
• Optional heat recovery via heat exchanger.

Advantages

• Regulatory compliance: meet required temperature and pH limits.
• Network protection: reduce risk of pipe damage and treatment disruption.
• Reliability and automation: sensors, alarms and remote supervision provide continuous control.
• Energy efficiency: optional recovery of thermal energy for reuse within the facility.

Additional information
Centrally managed alarms can be routed to the facility management system (BMS/BAS). Maintenance contracts are available for the complete process and system commissioning can be provided.

FAQ

• Why cool high-temperature hospital effluents? Hot discharges can damage piping, upset wastewater treatment plants and cause non-compliance with regulations.
• What is the maximum allowed discharge temperature? Regulations commonly require discharges below 30 °C with pH around 7.
• Which facilities are concerned? Hospitals, clinics, laboratories, sterilization units and certain industries producing hot effluents.
• Can heat from effluents be recovered? Yes, part of the thermal energy can be recovered using heat exchangers and reused locally.
