What is an EDS?
An effluent decontamination system (EDS), or biokill system, is a carefully designed system that sterilizes and neutralizes liquid waste from facilities dealing with potentially contaminated effluents.
We are here to share what we know.
We’ll walk you through the entire process
What is the source of the wastewater?
Do you know the expected volume or flow?
Do you need solids handling?
Which technology is the right fit?
Thermal, chemical or both?
Batch or continuous flow?
Redundant or non-redundant?

I was shocked that in one phone call, I knew we wanted a continuous chemical system, the ballpark cost, and that Bio-Response could provide it within our project’s lead time.
Thermal Batch
- Most common type of EDS.
- Meets the 121°C Standard (250°F); custom temperatures available.
- Available with or without significant agitation and solids handling.
- Can be built from duplex or super-austenitic grade stainless steels for extreme corrosion resistance.
- Many configurations available.
- Standard designs available to decrease engineering costs.
- Redundancy options available.
Thermal Continuous Flow
- Approximately the same cost as a thermal batch system.
- Up to 95% energy recovery.
- Operates on small fraction of the energy requirement of a thermal batch system.
- Can achieve very high treatment temperature (up to 150°C / 302°F).
- Cooling by regeneration eliminates the need for other cooling means (i.e. the need for cold water, tower water, or chilled water is eliminated).
- Can be designed to work in the presence of significant solids.
- Available in steam or electrically heated models.
- Can be built from duplex or super-austenitic grade stainless steels for extreme corrosion resistance.
- Many configurations available, from 4LPM to 250LMP (1-66 gpm) capacities.
- Gold standard for Thermal EDS efficiency.
- The future thermal technology for an energy conscious society.
- Standard designs available to decrease engineering costs.
- Redundancy options available.
Chemical Batch
- Less costly than thermal systems.
- Lowest energy consumption; no cooling required.
- Significant agitation is a standard feature.
- Works with a variety of chemicals; sodium hypochlorite is the standard.
- Very rapid sterilization; two turns per hour.
- Small systems, small footprint, large performance.
- Many configurations available.
- Exceptional EDS reliability.
- Standard designs available to decrease engineering costs.
- Neutralization and pH control available.
- Redundancy options available.
Chemical Continuous Flow
- Lowest cost of all systems.
- Lowest energy consumption; no cooling required.
- Works with a variety of chemicals; sodium hypochlorite is the standard.
- Flow and contact time are variable.
- Basic systems are relay logic for simplicity; PLC-operated versions available.
- Developed primarily for container labs and developing country applications.
- We build the best OEM solutions for developing country and modular applications.
- Standard designs available to decrease engineering costs.
- Neutralization and pH control available.
- Redundancy options available.
Thermochemical
- Lowest temperature – below 98 C.
- Lower energy use, lower cooling requirement.
- Lower cost of operation.
- Longer life and reduced maintenance.
- Chemicals are compatible with EDS materials and temperature.
- Can achieve sterility with or without heat, and with or without chemical.
- Automatic flexible redundancy available: System will recognize if heat or chemical source is out of order, and automatically modify cycle to achieve sterility.
- Can be built from duplex or super-austenitic grade stainless steels for extreme corrosion resistance.
- Has been validated at 93 C in BSL-4 facility.
- Many configurations available.
- Standard designs available to decrease engineering costs.
- Redundancy options available.
