Dissolved natural and manufactured organics, a high concentration of suspended particles (mainly faeces), and a diverse range of pathogenic and non-pathogenic organisms define residential wastewater.
Domestic wastewater has been treated using a variety of methods.
However, all of the processes have drawbacks, such as a large footprint, the emission of foul gases, the generation of foam, and the production of a large volume of sludge.
Enviro Janitors introduce a novel technology that has the following characteristics:
- Low foot print requirement.
- Low electrical energy consumption.
- Low operation and maintenance cost.
- Complete recyclability of the treated wastewater.
- No odour emission.
- No Sludge Generation.
Raw Water SOAT FICCO – CAACO
Treated Sewage for Discharge
Benefits from the stp after commissioning
- The treated wastewater would satisfy the discharging standards
- The treated wastewater can be used for greenery development in the community centre
- The treated wastewater can be used for flush outs.
- The treated wastewater can be used for aqua culture
- The solid waste production from the STP will be very minimum. It will be only the coarse / floating solids
- The STP would cater for more than 25 years without any alteration and replacement of materials.
The STP can be run only when the wastewater is generated .The STP need not be operated during holiday periods and on non functioning days.
Expected water quality parameters after treatment by our technology shown below
| Parameters | Parameters | Values |
|---|---|---|
| Unit operations required | Screening-grit chamber- equalisa-tion- oil &grease removal- Activat-ed Sludge process- Sand filtration – Activated Carbon filtration –Disinfection | Screening-grit chamber- equalisation- SOAR – FICCO-CAACO–Disinfection |
| Foot Print requirement | 1m2/m3 | 0.67 m2/m3 |
| Electrical Energy consumption | 550 units /day | 330 units /day |
| Sludge production | Dry sludge :0.3 kg/ m3Wet Sludge : 0.52 kg/ m3 Disposal only after treatment | Dry sludge :0.004 kg/ m3Wet Sludge : 0.0068 kg/ m3 Directly can be disposed |
| Operation cost | Rs. 16/m3 | Rs. 9/m3 |
| Odour emission | High | Trace |
| Future expansion | High | Trace |
| Foam Generation | Straw Yellow colour | Colourless like potable water |
| Colour of the treated waste water | Replacement of entire Unit opera-tions | Additional modules for the expand-ed volume |
| Replacement of materials | Replacement of sand and activat-ed carbon once in 6 months Plastic media once in 4 years | Replacement of catalyst once in 25 years |
| Treated water characteristics | COD: 80-100 mg/L, BOD : 20-30 mg/L Suspended Solids : 80-100 mg/L | COD: 30-40 mg/L, BOD : 5-10 mg/L Suspended Solids : 5-10 mg/L |
FICCO and CAACO technology can treat wastewater discharged from kitchens, toilets, and floor washings. The daily sludge production from wastewater is 0.0068kg/m3.
The purified water may be utilised at the community centre to create a green belt, flush the toilets, and raise the ground water table.
