Lystek International Inc. (Lystek) was founded in 2000 at the University
of Waterloo, Ontario to commercialize the treatment of biosolids and other
organic “waste”. The Lystek system was developed on the principles of cost
efficiency and long-term, environmental sustainability.
The result is an innovative, patented, low cost solution with multiple
benefits for converting wastewater treatment plants (WWTP’s) into
Resource Recovery Centres.
Lystek’s unique; hydrolysis process is award-winning and commercially
proven with multiple deployments.
High speed shearing, alkali and low pressure steam are simultaneously
applied in an enclosed reactor to transform raw sludge or digested biosolids
into a unique, multi-purpose material. The end result is a liquid product that
is rich in nutrients and organic matter but that also remains fully pumpable
with conventional handling and application equipment.
The system has a small foot print and is simple, modular and flexible. It can be
easily integrated into existing WWTP’s. Capital and operating costs are low
and it can be deployed as an on-site or off-site (regional service) solution.
Lystek is a financially strong company and our customers benefit from
ongoing investments in R & D and business growth.
“The addition of the state-of the-art, Lystek solution
to our WWTP operations is playing a vital role in
contributing to our goal of being a progressive, industry
leader in biosolids management.”

2. Lystek can be installed as an on-site, post anaerobic
digestion (AD), post dewatering solution. It does not
interfere with other WWTP processes. The process disintegrates
microbial cell walls and hydrolyses complex macromolecules into
simpler compounds.
This makes the residual volatile solids in digested biosolids more amenable
to further biodegradation when re-fed to AD and biological nutrient
removal (BNR) systems.
This is referred to as LysteMizing™.
LysteMized™ biosolids contain 40-50% of the total chemical oxygen
demand (COD) as soluble COD and significantly higher volatile fatty
acids, than standard biosolids. Therefore, they provide readily available
organics for AD and BNR systems.
In the AD process, recycling the hydrolysed product enhances
biodegradation of volatile solids. This can result in increased biogas
yields of 30%, or more and reduced output volumes of 20%, or more.
In BNR systems, the LysteMized™ product can be utilized as an alternative
carbon source, replacing costly, conventional products like methanol and
glycerol. Specific denitrification rates (SDNR) in LysteMized™ material
can be significantly higher than these commercial products.
Lystek can also accept raw sludge directly, producing a high quality
product without digestion.
