BSL3 Effluent Decontamination System
BSL3 Effluent Decontamination System: Custom Sizes, up to 2000 Litre

SANS 347 CERTIFIED

Astell manufacture a wide range of aqueous liquid Effluent Decontamination Systems (EDS) to service any BSL3 facility / laboratory. EDS are particularly suited for high containment facilities or high risk laboratories. As no two projects are likely to be the same, Astell Scientific offer comprehensive project management to guide you through the consultancy stage.
Rauserv c.c. in Johannesburg, South Africa can supply an Astell BSL3 Effluent Decontamination System to suit your application, Medical or Laboratory.

What can be treated?

Effluent types vary for each project, but typically treatable effluent sources will include:
  • Tap water from sinks and wash basins.
  • Water from washroom facilities within a containment area.
  • Sanitary installations such as toilets.
  • Water from showers and other cleaning facilities in the containment area.
  • Any exhaust/water from sterilizers used within the Category 3 or 4 area.

There are 2 types of sterilization processes that we offer when dealing with effluent decontamination systems. These are:

Batch Sterilization
This is one of the most commonly used methods. A system consisting of two or more tanks is installed, working on a run-standby system. When the first tank has reached a preset level, sterilization will begin and the second tank will switch to collecting any further waste. Upon sterilization completion, the first tank is emptied and will sit idle until tank 2 is full and begins sterilization. In this way, collection of effluent is not delayed whilst sterilization is being performed in one of the tanks.

Continuous Sterilization
This is similar to batch but often consisting of a holding tank. Contaminated waste is stored until a preset level is reached in the tank. This then triggers the start of the process. Once the process starts it will continue until the level of liquid in the tank is lowered to a shut down level or the flow of contaminated effluent from the facility stops.
