Description

About Fitec

We specialize in the design and engineering of self-cleaning digesters in North America. Our systems allow for the treatment of industrial, commercial and institutional food waste (IC&I), packaged and expired foods, organic waste from single and multi-family dwellings, source-separated organics (SSO) and manure from livestock.

Our systems ensure the efficient separation of non-digestible fractions of organic waste, including sand, both during pretreatment as well as in the process. Reference projects in Ontario and Nova Scotia verify the high efficiency of our process and components. Our special components are tested and manufactured at our own commercially operated biogas plant in Germany.

We are able to help with all stages of building a plant, from planning and design to project management and construction supervision. We will oversee the provision and installation of our system components, including our custom-made automation technology, provide support during commissioning and operational support thereafter to ensure the optimal functioning of our system.

The Fitec Process in Detail

 

Complete removal of contaminants in two stages

 

Stage I: Preliminary Treatment

Shredded waste with a total solids content of up to 25% are separated by a hydraulic press called the BioSqueeze. This removes 80% of the contaminants. To increase the separating capacity, the contaminant fraction is heated up to 70°C and passed through a second BioSqueeze press. The non-digestible (solid) fraction can then be composted, dried or directly disposed of. The digestible (liquid) fraction is pasteurized with a double-tube heat exchanger and then one or more digesters fed. In the digesters, biogas is generated from the digestible fractions and the biogas is used for the production of heat and power at a combined heat and power plant.
 

Stage II: Precision Treatment

The second stage of the separation of contaminants takes place continuously and directly within the digester.

Non-digestible solids (e.g. pieces of eggshells, glass, bone splinters, etc.) settle at the digester bottom. A floor grit cleaner removes these sinking contaminants. Floating contaminants like plastic or cork pieces are captured by a lightweight skimmer and discharged from the fermenter. This eliminates the periodic need to clean the digester tanks and allows for continuous and reliable operation of the plant.

The remaining digestate can be used as a liquid fertilizer. Alternatively, a solid-liquid separation step can produce a solid digestate (compostable) and a centrate. The centrate can be further purified by water treatment (e.g. SBR technology).
