Batch Process Systems
















AstellBio batch Effluent Decontamination Systems can be designed to operate as either gravity fed or pump driven, or a combination. Where it is possible to locate the EDS beneath the structure of the research facility, gravity can be harnessed to draw the waste water to the sterilizing tank(s). Pump fed Effluent Decontamination Systems become applicable where the tanks aren't sited below ground or in a basement location. Pumps are used to control the flow of effluent to the collection tanks. Whilst adding a little complexity, it does offer potential benefits to site location and is a highly configurable solution ideal for overcoming space limitations and layout challenges. Both feed types are capable of handling liquids and liquid/solid mixtures. A batch EDS system operates on a run-standby basis when more than one tank is specified.
Designed to your requirements
Features
- Colour touchscreen controllers showing permanent cycle status, pressures, temperatures, stage and cycle times, liquid levels
- Data archive, all cycles stored in memory and can be downloaded via ethernet and or captured via a printer (optional extra)
- Analogue and digital pressure displays
- Double valving on effluent input to protect incoming source
- Ability to manually override the whole system (password protected)
- Jacket heating and cooling on the sterilization pressure vessels
- Sterilization tank agitation to help heating and cooling times and stop solids from settling on the pressure vessels bottom
- Stainless steel pressure vessels
- Integral or external steam / heating supply
- Fully demountable for easy shipping and install
- Radar level controlling – for accurate tank level monitoring
- Steam sterilizable bacterial vent filters
- Inspection hatch
- Stainless steel pipework to first valve pipework, or all stainless steel pipework
- All connections are on the top of the pressure vessel to reduce liquid leaks on to the floor or the need to empty a pressure vessel to repair leaks. Connections can be flanged or Tri-clamp
- Clean in place (CIP) points to allow contaminated pipwork to be steamed for maintenance
- Pumped systems use magnetically driven pumps to reduce the likelihood of leaks
Options and Upgrades

Agitation to provide better heat distribution and distribute solids

Holding tank

Higher grade vessel material for special applications

Internal heating and cooling coil – to improve cycle times

Double valving on all valves

Hygienic instrumentation, valves, gauges and transducers

Cooling water recirculation – to reduce water consumption

Connection to a chilled water supply or a flow and return system to reduce water usage

Valve position monitoring

Full orbitally welded stainless steel pipework with tri-clamp connections

Fully insulated sterilization pressure vessels

Steam generators can be fitted to the plant to add redundancy for the site supply or be the main heating source

Automatic de-scaling system. An option to allow the system to be automatically de-scaled. This option does need some manual intervention

Sampling point to allow samples to be taken for sterility testing

Stainless steel frame made in sections to allow the plant to be stripped for shipping and easy installation
