Required area for constructing an STP is very less when compared with other treatment methods. Even your Septic tank will be converted into to STP. No other process tanks required
No chemicals required for the plant operation, even disinfection is managed by Ozone
Electrical load to run the STP is very minimum, when compared with the other treatment methods. Since its On-off system there is no need to run the plant for 24 hours. The power required by equipment is very low
There is no chemical required. Power consumption is also very less, On-off system and the footprint to construct a plant also very minimum, hence the CAPEX and OPEX reduced
There is no foul smell found around the STP area. Since the treatment method do not produce any obnoxious gases in the process
The quality of treated wastewater is very good, and meets the norms of standards prescribed by PCB. And moreover the water quality will not change while operation. It can handle shock loads also, hence the quality maintained constantly
This method of treatment can be easily understood by the plant operators even they are raw hands. The equipment is commonly available and there is no complicated monitoring process
