STP Plants
In INDION FMR, raw sewage enters from the top of the tank. In the aeration zone, air is introduced at the bottom of the tank through fine bubble diffusers. The media gets suspended due to the turbulence created by the air. Bacteria required for oxidation of the organic matter get attached to the media and some are suspended in the tank. After oxidation, the bacteria grow in number and need to be separated from the aeration tank liquor.
The lamella section inside the setting zone helps for clarification and separation of biomass (sludge) and clear water overflow into the chlorine contact tank.
Lamella plates help in increasing the setting area and removing the particles effectively in a smaller plant area. In the chlorine contact tank, sodium hypochlorite (NaOCI) is added to disinfect the clarified sewage.
Baffle plates are provided to increase contact time of treated sewage with chlorine.
Valves are used for sludge removal as well as MLSS (mother liquor suspended solids) adjustment.
The chlorinated, treated sewage then flows out of INDION FMR either for further treatment or for disposal.
Features
- Single tank design
- 1/3 space of conventional sewage treatment plant
- Uses high porosity moving media for bacteria to grow
- Useful for modification/ capacity extension of existing sewage treatment plant
Advantage
- Minimum land usage
- Minimum power & chemical requirement
- Low operating cost
Application
IINDION FMR deliver treated water to meet local discharge norms and be used as decentralized compact sewage treatment plant for housing complexes, hotels commercial complexes, industries and rural communities. The treated water can be used for gardening, toilet flushing and other law end application
Treated water quality (Domestic Effluent)
| Sample | After INDION FMR | After Tertiary Treatment |
| BOD | 30ppm | 5ppm |
| COD | 100ppm | 20ppm |
| Total suspended solid | <30ppm | <5ppm |
| Oil & grease | <10 | <10 |
The INDION FMR is also suitable for industries effluent piloting may be required to establish sizing and to obtained the treated water characteristics
