6. Lystek Technology – Overview
• Low Temperature Physical Chemical Hydrolysis Technology
- A back-end solution, installed after dewatering
• Produces a multi-purpose, hydrolysed product for:
- Anaerobic Digester Enhancement
• Improve biogas yields by >30%
• Reduce biosolids volumes by >20%
- BNR System Enhancement – a cost effective, alternative carbon
source
- Liquid biofertilizer – CFIA registered (Canada) / Enhanced treated
(UK)/ Class A EQ (USA) – high organic matter & NPK – interest and
demand from farm sector is exceptionally high
7. Technical/Scientific Basis
• Cell disintegration & hydrolysis of complex organic molecules into
simpler compounds
• Process makes the residual recalcitrant volatile solids in digested
biosolids more amenable to further biodegradation when re-fed to
anaerobic digester = “LysteMize”
• Hydrolyzed product provides readily available organics for AD and BNR
system + nutrients for soil/plants
• Product contains >40% of the TCOD as SCOD
• Product contains 10-fold higher VFA as compared to standard, biosolids
cake
8. Lystek vs. Typical Thermal Hydrolysis
Items Typical Thermal Hydrolysis Lystek Hyrdrolysis
Technology High temperature, high pressure
hydrolysis
Low temperature, high shear,
physical-chemical hydrolysis
Process
condition
160-170oC for 20 - 60 min @
100 - 130 psi, multiple steps
70-75oC, 45 min, pH 9.5–10.0, high
shear, atm. Press., one step
Heat source High pressure steam boiler Low pressure steam boiler or CHP
Installation Prior to anaerobic digestion,
interferes with existing WWTP
processes
After anaerobic digestion and
dewatering, no interference with
existing WWTP processes
Side stream /
residues
High N centrate from first stage
dewatering - extensive
treatment
None
Dewatering Two stage: pre- and post-AD One stage conventional after AD
Footprint Large Small

23. Digester and BNR System Enhancement
• Improved biogas yields in Anaerobic digester
- Independent lab studies at Canadian and the US Universities and
onsite pilot tests have shown potential of re-feeding Lystek biosolids
to anaerobic digester
- Lystek processed biosolids are 50-60% further biodegradable
- 30-50% more biogas potential with Lystek product
• Carbon source Enhanced BNR system
- Independent lab studied have indicated potential of Lystek biosolids
as carbon source in BNR system
- Lystek biosolids shows equal or higher specific denitrification rates
(SDNR) (mg NOx-N/mg VSS) compared to conventional glycerol,
methanol or acetic acid
