Continuous Flow EDS

The Bio-Response Continuous Flow EDS is the ultimate system for your energy recovery needs. This EDS allows a constant flow for high capacity and is available in many sizes and configurations. We utilize a tube in tube heat exchanger for increased solids handling and reliability, yet achieve a 90% energy recovery. The system shown at the left operates at 15 liters per minute and features a 27,000 liter collection tank and redundant processing skids. The system is able to run one skid, automatically switch to the other, or run both depending on the rate at which it is receiving biowaste water from the lab. The skids are specifically designed to hold the effluent at full temperature for the desired time period and any effluent that is measured below temperature during heatup is automatically sent back through to be treated once more.

Low Temperature Continuous Flow Pros/Cons

Advantages (Pros) Operates at 85°C+ / 185°F+
Continuous operation
Operates with no backpressure devices
Low energy consumption
No cooling necessary
Ideal for Level 1 and Level 2 organisms
Can treat pathogenic spores (species, contact, and temperature dependent)
Could be used with a chemical catalyst (thermochemical)
Variety of heating methods available
Up to 90% energy recovery
 
Disadvantages (Cons) Solids intolerant (minimal solids controlled with strainer baskets)
Higher cost system
Requires substantial space (for service accessibility)
Requires a pump (reliability)
Requires a flow measurement system (reliability)
Requires an incoming filtration system
Requires periodic acid and base washes to remove protein buildup and scale
How long did the material remain in the hold tubes? We oversize them for proper hold time, but it is a question regardless of who builds the system
 
General Discussion Energy recovery (low energy consumption, no cooling water consumption) is the only reason to consider continuous flow technology. These systems tend to be high maintenance in comparison to continuous batch systems. Price is comparable to continuous batch systems. They are heated by indirect steam (heat exchanger) or by direct steam injection. Commonly used for Level 1 and Level 2 organisms.

 

High Temperature Continuous Flow Pros/Cons

Advantages (Pros) Operates up to 150°C / 302°F
Continuous operation
Low energy consumption
No cooling necessary
Can sterilize thermostable spores including Geobacillus stearothermophilus due to the high temperature capability
Variety of heating methods available
Up to 90% energy recovery
 
Disadvantages (Cons) Solids intolerant (minimal solids controlled with strainer baskets)
Higher cost system
Requires substantial space (for service accessibility)
Requires a pump (reliability)
Requires a flow measurement system (reliability)
May require an incoming and outgoing filtration system due to solids (service)
Requires a backpressure device (reliability, potential for failure, and flashing release)
Requires periodic acid and base washes to remove protein buildup and scale
How long did the material remain in the hold tubes? We oversize them for proper hold time, but it is a question regardless of who builds the system
 
General Discussion Energy recovery (low energy consumption, no cooling water consumption) is the only reason to consider continuous flow technology. These systems tend to be high maintenance in comparison to continuous batch systems. Price is comparable to continuous batch systems. They are heated by indirect steam (heat exchanger) or by direct steam injection. Primarily used for Level 3 organisms.
