O2FIX® 21 to 50 EH
Biological treatment plant
Biological treatment of domestic wastewater
Avantages :
- Conformity: complies with the most stringent French (ministerial order of 21 July 2015) and European (EN 12566-3) standards and regulations. Model tested according to the performance tests of CE marking and assessed for the variations in load and intermittent nature.
- Decennial warranty via insurance supplemented by an Epers
- Light and inert materials to domestic wastewater
- Versatility: possibility to reinforce in the presence of a water table
- Performance and reliability: double primary settling (better primary settling and grease retention, buffering of peak flow rates, more active anaerobic digestion of primary sludge) and biological reactor with fluidised bed (purification performance, clog-free media, low energy consumption, low production of biological sludge, high-yield air distributors)
- Easy installation: low encumbrance on the ground and model suited for installation in all conditions on the terrain (reduced plots, terraced or sloped terrain, presence of groundwater, under road surface, above ground...)
- Economic model: delivered ready-to-install, simple model with reliable operation, model easy to relocate
- Compact installation: buried installation, partially buried or above ground with long installation, as an L or as a U
Taille :
21 to 50 EH
Application :
The O2FIX® compact biological treatment plant is intended for treating domestic and industrial wastewater:
- from small collective units, villages or hamlets
- of housing developments, public buildings
- hotels, bed and breakfast and camp grounds
- commercial and industrial sites
- for living set-ups, sites and camps
Conception :
- Polyethylene tank with ribbed structure with reinforcements
- Maximum backfill height above the tank (under green spaces): 0,38 m
- Biological reactor with fluidised bed with high-performance media support (biological specific surface: 850 m²/m³)
- Gravity and modular design with 4 tanks according to installation constraints
- Connections using pipes
- 1 access well per tank with cover Ø 600 made of A15 combined with an access hatch
- Control panel for wall installation and installation in a building. Idem for the compressor.
Fonctionnement :
The O2FIX® biological treatment plant is comprised of:
- double tank primary settler: run-of-river pretreatment, settling of TTS, grease retention, optimisation of anaerobic digestion of sludge (primary and biological with surplus storage) aiming to reduce the volume of sludge to be extracted.
- biological reactor with fluidised bed: design validated by hydraulic control combined with the properties of the biological support and with the performance of the air distributors supplied by a compressor with high reliability.
- secondary settler: separation of biological sludge before discharge; excess sludge is then withdrawn and transferred to the primary settler. The treated water can be discharged into the surface environment or via infiltration into the ground or be re-used after a post-treatment.
