20 m³/day Integrated Domestic Sewage Treatment System In Guangdong
This Guangdong project uses an above-ground integrated system to treat domestic sewage generated at an industrial site. The 20 m³/day equipment combines activated-sludge aeration, biological conversion, solids separation, sludge return and PLC-based control in a compact equipment body.
Integrated equipment installed above ground
The enclosed treatment body includes service doors, ventilation details and visible site pipe connections.

Why An Integrated Activated-Sludge System Was Used For This Project
The 20 m³/day capacity, domestic sewage source and compact installed equipment form suit a decentralized biological-treatment duty rather than a large conventional plant layout.
Small Decentralized Flow
At 20 m³/day, an integrated package system keeps the main treatment functions together for a site that does not require a large municipal-style plant.
Biodegradable Domestic Load
Activated sludge uses suspended biomass to reduce biodegradable organic matter. Final sizing still depends on COD, BOD₅, TSS, ammonia, temperature and peak-flow data.
Accessible Above-Ground Layout
The installed enclosure keeps doors, valves, pipe connections and equipment access visible above ground, which supports inspection and routine service planning.
Biological Treatment And Control In One Equipment Body
Four connected functions define the activated-sludge system: oxygen supply, biological conversion, solids separation with sludge return, and automated control.
Oxygen Supply For Active Biomass
Aeration transfers oxygen into the biological zone so aerobic microorganisms can metabolize biodegradable organic matter.
Activated-Sludge Conversion
Suspended biomass adsorbs and degrades organic pollutants, converting part of the load into biomass, carbon dioxide and water.
Sedimentation And Sludge Return
Gravity separation removes biological solids from the water. Returning part of the settled sludge helps maintain active biomass in the treatment system.
PLC-Based Equipment Control
PLC-based control supports automated equipment sequencing and routine status management. Exact instruments, alarms and control points are defined for each proposal.
Installed Pipework And Service Access At The Guangdong Site
At the installed unit, the integrated body meets the concrete foundation while external pipes, valves, vents and access doors remain accessible around the equipment.
Equipment Interfaces Visible For Site Coordination
The installed view gives buyers a practical reference for the interfaces that must be coordinated between equipment supply and site construction.
Treatment Functions In The 20 m³/day System
These are the main functions named for the Guangdong equipment and the engineering role each function performs in an activated-sludge treatment system.
| Treatment Area | Project Configuration | Engineering Role |
|---|---|---|
| Biological Aeration | Activated-sludge aeration with oxygen supply | Supports aerobic biomass activity and the reduction of biodegradable organic matter. |
| Organic Conversion | Biomass adsorption and biological degradation | Converts biodegradable pollutants into additional biomass, carbon dioxide and water. |
| Solids Separation | Gravity sedimentation after biological treatment | Separates biological solids from clarified water so biomass can be retained or removed. |
| Sludge Return | A portion of settled activated sludge returned to the biological stage | Maintains an active biomass inventory. Return rate and excess-sludge handling are project design values. |
| Automation | PLC-based equipment control | Supports sequencing and operating-status management; exact I/O, alarms and remote functions are defined separately. |
For a new site, Motiva confirms the complete route from actual water data and outlet limits. Pretreatment, disinfection, sludge handling, tank sizing and the final control scope are selected during project design.

Prepare Design InputsAnswers For Buyers Evaluating A Similar System
These answers separate the visible project facts from the water data and design decisions required for a new domestic sewage treatment system.
What is the capacity and wastewater source for this project?
The treatment capacity is 20 m³/day. The equipment was supplied for domestic sewage generated at an industrial site in Guangdong Province, China; it should not be interpreted as a treatment reference for the site's industrial process wastewater.
Which biological process is used in the Guangdong system?
The Guangdong system uses an activated-sludge process. Its main functions include aeration, biological adsorption and degradation, gravity sedimentation and return of part of the settled sludge.
What does the integrated equipment combine?
The case confirms the core biological-treatment and control functions in an enclosed equipment body. A new supply list must separately confirm pretreatment, disinfection, sludge handling, pumps, blowers, instruments and installation services.
Is the system installed above ground or underground?
The Guangdong project photographs show an above-ground installation on a concrete foundation. Integrated systems can be configured differently for another site after access, civil works, groundwater, ventilation and maintenance requirements are reviewed.
Did the project meet the DB44/26-2001 Class I standard?
The Guangdong system was specified around a DB44/26-2001 Class I outlet objective. Compliance should be evaluated against the applicable current limits and verified commissioning or operating data before discharge or reuse decisions are made.
What data is needed for a similar 20 m³/day project?
Send the wastewater source, average and peak flow, COD, BOD₅, TSS, ammonia and other available analysis, the current outlet target, site dimensions, utilities, access conditions and the required equipment, installation and commissioning scope.
