Depending on the application, a 500 KLD STP can be designed using technologies such as MBBR, SBR, MBR and other suitable biological treatment processes.
What Is a 500 KLD Sewage Treatment Plant?
KLD stands for Kilo Litres per Day.
Therefore:
500 KLD = 500,000 litres per day = 5 lakh litres per day
A 500 KLD sewage treatment plant is designed to handle approximately 500,000 litres of domestic wastewater each day under its specified design conditions.
The sewage may originate from:
- Residential buildings
- Apartments
- Toilets and bathrooms
- Hotels and resorts
- Hospitals
- Schools and colleges
- Office buildings
- Commercial facilities
- Institutional campuses
The wastewater passes through multiple treatment stages before the treated water is directed toward an appropriate reuse or approved discharge arrangement.

- More structured wastewater management
500 KLD Sewage Treatment Plant Process
The treatment process for a 500 KLD STP depends on the selected technology and project requirements.
A typical system can include the following stages.
1. Screening
Raw sewage first enters the screening system.
Screens remove larger materials such as:
- Plastic
- Paper
- Cloth
- Sanitary waste
- Floating debris
This preliminary treatment helps protect pumps, pipelines and downstream equipment.
2. Grit Removal
Where required, a grit-removal system can be provided to separate heavier inorganic particles.
Removing grit helps minimize unwanted accumulation and can protect mechanical equipment.
3. Equalization
The equalization tank helps balance variations in wastewater flow throughout the day.
Since sewage generation changes according to occupancy and facility usage, equalization can provide a more consistent feed to the biological treatment stage.
4. Biological Treatment
Biological treatment is the core stage of many sewage treatment plants.
Microorganisms consume biodegradable organic matter present in sewage.
Depending on the project, the biological process may use:
- MBBR
- SBR
- MBR
- Activated sludge process
- Other suitable biological configurations
5. Secondary Clarification
After biological treatment, biomass and suspended solids are separated from the treated wastewater through clarification or another suitable solids-separation process.
This prepares the water for further filtration and disinfection.
6. Tertiary Filtration
Tertiary treatment may be incorporated to further polish the treated wastewater.
Typical equipment can include:
- Pressure sand filter
- Activated carbon filter
- Micron filter
- Other filtration systems
The exact configuration depends on the required treated-water quality.
7. Disinfection
Disinfection helps reduce microorganisms in the treated water.
Depending on the project, suitable disinfection methods can include:
- Chlorination
- UV disinfection
- Other appropriate systems
8. Treated Water Storage
After treatment and quality verification, treated water can be transferred to a storage tank.
It may then be used for approved non-potable applications or routed to an appropriate discharge arrangement.
