What Is an Integrated Sewage Treatment Plant?
An integrated STP combines screening, biological treatment, sedimentation, and disinfection into a single factory-assembled unit. No need for multiple separate tanks — everything arrives ready to connect. Just pipe in the wastewater and connect power.
How It Works
Four-Stage Treatment Process
Screening
Remove large solids and debris from incoming wastewater
Biological Treatment
A/O process breaks down organic matter using activated sludge
Sedimentation
Settle and separate activated sludge from treated water
Disinfection
UV or chlorine treatment for final pathogen removal
Key Advantages
Why Choose an Integrated STP?
Compact Footprint
Saves 50% space compared to traditional multi-tank systems
Fast Installation
Up and running in 2-3 days — just connect pipes and power
Low Operating Cost
Fully automated control system reduces labor and energy use
No Odor
Sealed design prevents odor escape — safe for nearby buildings
Mobile & Transportable
Containerized design allows relocation to new sites
Meets Discharge Standards
Standard models meet GB 18918-2002 Level 1B; MBR upgrade meets Level 1A

FAQ
Frequently Asked Questions
How long does installation take?
Most integrated STPs can be installed and commissioned in 2-3 days. The unit arrives fully assembled — you just need to connect inlet/outlet pipes and the power supply.
Does it need a separate building?
No. The unit is designed for outdoor installation with a sealed, weatherproof enclosure. For underground installation, we provide reinforced models.
What discharge standard does it meet?
Standard models meet Chinese GB 18918-2002 Level 1B. With the MBR option, it meets Level 1A or reuse standards. We can adjust the process to meet your local standards.
What maintenance is required?
Routine maintenance includes checking pump operation, cleaning the screen every 1-2 weeks, and periodic sludge wasting. The fully automated control system monitors key parameters 24/7 and alarms when attention is needed. We provide a detailed operation manual and remote technical support.
Product Overview
What Is Integrated Sewage Treatment Equipment?
Integrated Sewage Treatment Equipment (also known as packaged STP or compact wastewater treatment plant) is a factory-assembled, all-in-one system that combines multiple treatment processes into a single unit. It integrates screening, biological degradation, sedimentation, and disinfection — all inside a compact tank or container.
Unlike traditional wastewater treatment plants that require building multiple separate concrete tanks, an integrated STP arrives on site fully assembled and tested. You simply connect the inlet pipe, outlet pipe, and power supply, and the system is ready to run. This plug-and-play design dramatically reduces installation time and civil work costs.
Integrated STPs are ideal for small to medium flow rates (5-500 m³/day) where space is limited or where a fast deployment is needed. They are widely used in residential communities, hotels, schools, hospitals, construction sites, and small industrial facilities.
Key Benefits
Why Choose Our Integrated STP?
Four core advantages that make our integrated sewage treatment equipment the smart choice for small and medium wastewater projects.
01
Space-Saving Compact Design
Combines all treatment stages into one unit, saving up to 60% of floor space compared to traditional multi-tank systems. Perfect for sites with limited land area.
02
Fast Installation & Commissioning
Factory-assembled and tested before shipping. On-site installation takes only 2-3 days — just connect pipes and power. No complicated civil engineering required.
03
Fully Automated Operation
Equipped with an intelligent PLC control system that runs 24/7 without constant manual supervision. Alerts are sent automatically if any parameter goes out of range.
04
Low Operating & Maintenance Cost
Efficient pump and aeration design reduces energy consumption. Sealed structure prevents odor escape. Simple maintenance with only periodic checks and sludge removal.
Product Types
Three Types of Integrated STP
Choose the right model based on your wastewater characteristics, effluent requirements, and installation conditions.
MBR Integrated
MBR Integrated STP
Combines A/O biological process with MBR membrane filtration for the highest effluent quality.
- Effluent meets GB 18918-2002 Level 1A
- SS < 5 mg/L, suitable for water reuse
- Smaller footprint, higher MLSS
- Ideal for strict discharge standards
A/O Integrated
A/O Integrated STP
Classic anaerobic/oxic + sedimentation process, the most cost-effective choice for standard requirements.
- Effluent meets GB 18918-2002 Level 1B
- Lower investment and operating cost
- Simple and reliable operation
- Best for general domestic sewage
Buried Type
Buried Integrated STP
Underground installation model with reinforced structure, completely hidden below ground level.
- No impact on surface landscape
- Good thermal insulation for cold climates
- Reinforced tank for soil pressure
- Top can be used for greening or parking
