Symbiona SA products

In this system, clean water is separated from waste sludge by membranes (on a cellular level). We use high quality submerged modules (AeroMem™-SUB, which can be installed either in the aeration tank or in a separate membrane tank, with MLSS up to 16g/l) or external membrane systems for very high MLSS concentrations (AeroMem™-X, up to 25g/l).

The use of high surface carriers (>650m2/m3) floating in the biological reactor results in controlled growth of biofilm bacteria in the aerobic reactor. The system can be used for biological filtration (MBBR, MBBR-BNR) or coupled with activated sludge (IFAS), where additional denitrification is required. These systems offer high stability for toxic compounds and changing flows, with a very small surface required to remove high COD loads. In case of high effluent discharge limit, a membrane system can be included to remove the solids in a hybrid MBBR-AeroMem™ system.

Wastewater flows through biological reactor in continuous plug-flow system ended with a clarifier for waste biological sludge and effluent separation. In case of our flotation biological reactors (FloFBR™) traditional clarifier is replaced by sludge flotation as activated sludge clarifier. It makes the system more compact, due to a higher concentration of MLSS in the aeration tank.

Well known process operating in single tank or multiple tanks. All processes required to clean wastewater are used in one one tank or series of tanks with nitrification, and nitrogen removal. Process could be simplified or in full automation.

For old type oxidation ditches we supply our own aerating brush rotors. They are usually coupled with automated weirs and oxygen control to provide cost-effective organic load removal.

Top of the top, with to 99% of COD removal, own proprietary anaerobic reactor combinig the best from two worlds – flocullent sludge and memrbane technology as separator. Best for very high COD effluents (up to over 200.000mg/l) that contains lot of TSS up to over 50.000mg/l. Suitable also for treatment of mixes of wastewater and slurries or organic factory waste (ie. flotation sludge, chocloate scrap).

High-rate methane fermentation reactors AnoxyBed combbines high COD removal performance with minimal footprint. Symbiona AnoxyBed™-EGSB/UASB/DAG anaerobic systems proven as robust and flexible for industrial effluents. depending on TSS levels and temperatures we propose either AnoxyBed™-EGSB (expanded Granular Sludge Bed) reactors with high capacity settlers or our AnoxyBEd™-DAG (downflow attached growth) anaerobic carrier system. AnoxyBed™-D is used especialy for repowering existing aerobic plants into anaerobic ones. We also offer services of renovation of exiting plants in EGSB, UASB, IC technologies.

Compact units for fats and TSS removal. Could be delivered as stainless steel units, as well as concrete build for high flows.
Designed in The Netherlands for top quality.Flotation unit for activated sludge – FBR: Designed for aerobic activated sludge. Used in flotation aerobic reactors or in sludge thickening/recovery.

Patent pending, high rate clarifiers for activated sludge: especially for efficient clarification of anaerobic slurries or MBBR sludge with low viscosity and specific gravity.

High speed systems for surface water treatment, both for industrial and municipal use. Typically delivered as stainless steel or concrete build for high flows.
