Effluent Decontamination Systems (EDS) - Introduction

Effluent Decontamination Systems (EDS) are required to treat all laboratory wastewater/effluent produced within high level bio-containment boundaries. This effluent typically originates from the laboratory sinks, showers, floor drains, and autoclaves. EDS are recommended, and/or required by law, across the world for facilities classified as Bio-safety Level 3 and Level 4 (BSL-3 and 4). Effluent Decontamination Systems use a combination of heat and pressure to ensure that any potentially dangerous microbiological agents in the effluent are destroyed before release to the public sewer. Typically these systems are located in sub-contained basement areas directly below the laboratories which they serve. This allows for a gravity flow into the system which minimizes any further intermediate equipment. In some cases, where it is not possible to gravity feed the system, a collection tank is incorporated. Effluent Decontamination Systems can operate as continuous or as a continuous-batch process, the latter of which is the chosen standard for WR2 systems due to the inherent safety control and containment advantages.

WR2 Effluent Decontamination Systems offer our customers the best available standard in bio-safety. From the initial system configuration to the individual components and control systems used, the equipment is designed specifically to operate safely and continuously, even in emergency situations in a high bio-containment environment. We offer a wide selection of configurations and capacities from small under-the-sink units to systems designed to treat thousands of gallons per day.

Our highly experienced team of engineers and bio-safety experts ensure that the WR2 EDS are not plagued by the problematic issues such as sedimentation and solids handling and the formation of “cold spots”. In addition, individual system components such as HEPA filters, pumps, and all plumbing are fitted with decontamination ports as standard equipment to allow for isolation and steam sterilization in the event of routine or emergency maintenance.

WR2 is also able to offer a unique “prion cycle” feature, incorporating patented WR2 Alkaline Hydrolysis technology, for the safe disposal of potentially TSE infected effluent.
