The Batch Effluent Decontamination System typically features a sterilizing tank and one or more holding tanks, although a single tank solution is available by request.

Astell manufactures a wide range of aqueous liquid Effluent Decontamination Systems (EDS) to service BSL-3 category facilities. EDS are particularly suited to enclosed containment or high risk research laboratories dealing with dangerous biological agents. As no two EDS projects are likely to be the same, Astell Scientific offers comprehensive advice and project management to guide you through the consultancy stage. All units are built to order and as such are highly configurable.

One of the most commonly used methods, the AstellBio batch EDS system consists of two or more tanks, 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 two is full and begins sterilization. In this way, collection of effluent is not delayed whilst sterilization is being performed in one of the tanks.
