Helping nature do its job, just faster and better

The Organica cascade is a continuous-flow treatment process through a series of connected biological reactors.  In the reactors, a fixed biofilm is maintained in every stage of the cascade so that the biodegradation takes place primarily with the help of fixed biological cultures.

Plant roots are used as the main biofilm carriers, and artificial media are used in the reactors as additional biofilm carriers. Hence, the common acronym use for Organica’s technology – Fixed-Bed Biofilm Activated Sludge (FBAS)

In each reactor, anaerobic or aerobic conditions are created, allowing the propagation of organisms that drive the key reactions for wastewater contaminant transformation and removal.

The flow of the water
In the cascade, the wastewater flows through a series of reactors that are configured and operated to allow the development of distinct ecosystems arranged to form a complex network. After passing through the reactors, the water enters the final clarifier and the effluent is discharged to the recipient.  The sludge treatment method depends on the project. In most cases, the supernatant of the sludge flows back into the equalization basin via internal recirculation lines in order to maintain a robust microbial population for treating the wastewater.

Odor free
There are very few steps in a treatment process that generate odor, and these steps are carefully isolated. First, the air is captured in a closed system and then is biologically filtered to remove the odorous compounds. The result is an odor-free greenhouse garden.

Change of biomass, reduction of waste
There is a large amount of biomass at the beginning of the aerobic cascade due to the abundant supply of organically decomposable materials. At the end of the cascade, however, biomass is reduced dramatically. This reduction is due to the presence of food chains in the complex ecosystems. In these evolved food chain networks, the microbes and associated biomass are consumed by predators, significantly reducing sludge and its associated processing costs.
