ENHANCE DIGESTER & BNR SYSTEMS

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.”

One System Multiple Benefits for Biosolids & Organics Management

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.
