Integrated Sewage Treatment And DAF Equipment For Hohhot Urban Wastewater
Motiva supplied an integrated sewage treatment unit together with dissolved air flotation equipment for an urban wastewater management project in Hohhot. The project record identifies pretreatment, biological treatment and advanced purification functions, while factory photographs show the equipment prepared for dispatch.

Two Equipment Packages For One Urban Wastewater Project
The case combines an enclosed integrated sewage treatment unit with a separate dissolved air flotation system. Together they address staged wastewater treatment and the separation of floatable or hard-to-settle material.
Project At A Glance
| Location | Hohhot, Inner Mongolia, China |
|---|---|
| Wastewater context | Urban domestic sewage management |
| Integrated equipment | Enclosed sewage treatment unit with pretreatment, biological treatment and advanced purification functions identified in the source |
| Companion equipment | Dissolved air flotation system for separation of suspended solids, oils and other floatable impurities |
| Control approach | Automated operation stated for the integrated system |
| Project stage | Equipment supplied; source record reports on-site installation underway |
What This Case Confirms
The source confirms the project location, urban sewage application, integrated treatment unit, DAF equipment and reported installation stage. It does not provide capacity, water-quality values, a final process flow diagram or commissioning results.
Why Integrated Treatment And DAF Were Combined For This Project
The supplied equipment separates two engineering roles: an integrated unit concentrates the main treatment functions in a factory-built enclosure, while DAF adds a physical-chemical separation step for fine, light or floatable material.
Compact Process Integration
Prefabricating the main equipment package consolidates multiple treatment functions, mechanical interfaces and control requirements before site installation.
Targeted Solids Separation
DAF uses fine air bubbles to attach to light particles and floatable matter so they can be collected at the surface instead of relying only on gravity settling.
Project-Specific Coordination
The DAF location, coagulant strategy, biological load and downstream polishing must be coordinated as one system from the actual influent and discharge target.
Integrated Sewage Treatment Unit And DAF System
The project record identifies two principal equipment packages. The internal process details remain project-specific, but each package has a clear treatment role and a visible factory-delivery form.
Integrated Treatment Enclosure
The enclosed unit is identified as combining pretreatment, biological treatment and advanced purification functions within the supplied system.
Dissolved Air Flotation Equipment
The separate DAF unit is intended to remove suspended solids, oils and other floatable impurities through microbubble-assisted flotation.
Automated Equipment Operation
Automated operation is stated for the system. The final control cabinet, instruments, alarms and remote-access scope should be confirmed for each new project.
Both Equipment Packages Prepared For Project Dispatch
The second factory view shows the enclosed integrated unit and the DAF equipment on the same transport vehicle, providing direct visual evidence of the combined project supply.

The photograph distinguishes the large enclosed treatment body from the DAF equipment, piping and electrical-control components staged for transport.
How The Supplied Equipment Fits A Project-Specific Treatment Route
This is a functional equipment map, not a complete process flow diagram. The final sequence, tank volumes, chemical program and control points must be set from the Hohhot project design or recalculated for a new site.
| Treatment Area | Confirmed Project Equipment Or Function | Engineering Role And New-Project Inputs |
|---|---|---|
| Integrated Pretreatment | Pretreatment is named as a function inside the integrated treatment system | Define screening, flow equalization and any upstream solids control from peak flow, debris, grit, oil and suspended-solids loading. |
| Biological Treatment | Biological treatment using microbial degradation is identified in the source | Select the biological process, aeration, recycle, sludge age and zone volumes from COD, BOD₅, ammonia, TN, TP, temperature and outlet limits. |
| Dissolved Air Flotation | Separate DAF equipment supplied with the integrated unit | Size hydraulic loading, recycle pressure, air-to-solids ratio, coagulation and skimming from TSS, oil, colloids and treatability testing. Its final position in the route must be confirmed. |
| Advanced Purification | Advanced purification is named as a system function; the individual stage is not specified | Confirm clarification, filtration, disinfection or other polishing only after the discharge or reuse target is defined. |
| Automation And Site Interface | Automated operation is stated; control components are visible with the shipment | Define PLC/HMI scope, instruments, alarms, remote access, foundation, piping, power, crane plan and installation responsibilities for the new project. |
A similar system should be selected only after average and peak flow, influent water quality, required outlet limits, site layout, climate, utilities and operating responsibilities are confirmed.
Equipment Supplied For Hohhot; Installation Reported Underway
The project source states that Motiva supplied the integrated treatment and DAF equipment and that on-site installation was underway. The available photographs document factory dispatch preparation; commissioning and measured operating results are not included.

Prepare Design InputsQuestions About The Hohhot Integrated Treatment And DAF Project
The answers separate confirmed project facts from the engineering decisions that still have to be made for a new urban sewage treatment system.
What equipment was supplied for the Hohhot project?
The project record identifies an integrated sewage treatment unit and a dissolved air flotation system as the main supplied equipment packages.
What role does the DAF system perform?
Dissolved air flotation uses microbubbles to lift suspended solids, oils and other floatable impurities to the surface for removal. Its sizing and chemical program depend on the actual wastewater.
Was DAF installed before or after biological treatment?
The available project record does not identify the final DAF position. For a new project, its location is selected from influent solids and oil loading, biological-process protection needs and the required outlet quality.
Which biological process is inside the integrated unit?
The source confirms biological treatment using microbial degradation but does not name the process family or internal zone arrangement. These details should be confirmed in the final process design.
Is the Hohhot system operating?
The source reports that equipment was supplied and on-site installation was underway. No commissioning report or measured operating data is included in the available record.
Can the same integrated treatment and DAF combination be used for another city?
The equipment combination can be evaluated, but it is not a universal template. Capacity, process sequence, DAF chemistry, biological loading and polishing stages must be recalculated from the new wastewater and outlet target.
What data is needed for a similar urban sewage project?
Send average and peak flow, COD, BOD₅, TSS, oil and grease, ammonia, TN, TP, pH, temperature, discharge or reuse target, site layout, utilities and required supply scope.
Request An Integrated Treatment And DAF Review
Send one set of project inputs through the shared Motiva RFQ / Water Data Form so the integrated equipment, DAF role, biological route, control scope and site interfaces can be reviewed together.
