BIOdek
Features:
BIOdek's crossflow design offers performance Advantages not Found in other synthetic media.
- BIOdek is often used as a direct replacement for rock media for increasing bopth the degree treatment and capacity of existing trickling filters.
- BIOdek's uniform and continuous crossflow provides superior air and water distribution throughout the media, eliminating the need for forced air ventilation even in large diameter trickling filters.
- BIOdek greatly increases the contact time of the wastewater within the media, resulting in high efficiency with minimum recirculation.
- Large depths, 6 meters or above, even without intermediate supports, allow considerable saving of land and also increased retention time. This combined with efficient geometry, can offer a very compact plant.
- Due to continuous redistribution of water flow, the media a very high resistance to plugging.
- Settling effluent Total Suspended Solids (TSS) is much lower.
- No elaborate peripheral walls are required because modules are self supporting. Only lading suffices.
- Shallow media depths and minimum recirculation rates reduce pumping costs and make BIOdek the most cost-effective media available.
- BIOdek has proven effective in removing BOD at hydraulic wetting rates below 0.6m 3 /m 2 /hr to over 7m3 /m 2 /hr.
Applications:
BIOdek biological treatment media has numerous applications in wastewater treatment. The shape of the media has a significant influence on application and must be considered along specific surface area and void ratio. Applications are as follows
- Upgrading existing rock trickling filters.
- BOD Reduction in Trickling Filters
- Complete Secondary Treatment.
- Trickling Filters/Solids Contact (TF/SC)
- Roughing of pre-treatment.
- Nitrification.
- Denitrification.
- Odour Scrubbing.
- Anaerobic Treatment
ANAEROBIC DIGESTOR - SAFF or submerged aerobic fixed film reactors.
